RESUMO
Microbial dysbiosis is increasingly understood to influence allergic sensitization and skin barrier defects in dermatitis. Occlusion, such as from moisturizers, fosters microbial dysbiosis, and increases itch in many patients with dermatitis. Nevertheless, use of moisturizers in dermatitis remains part of dermatologic guidelines. This is a review of the evidence of benefits and adverse effects of moisturizers in dermatitis and a proposal for moderation in their clinical use.
RESUMO
The pathogenesis of atopic dermatitis (AD) is complex and multifactorial. However, recent advancements in the genetics and pathophysiology of AD suggest that epidermal barrier dysfunction is paramount in the development and progression of the condition (Boguniewicz M, Leung DYM, Immunol Rev 242(1):233-246, 2011). In addition to standard therapy for AD, there are a plethora of nonprescription treatment modalities which may be employed. Over-the-counter treatments for atopic dermatitis can come in the form of topical corticosteroids, moisturizers/emollients, and oral antihistamines. Though these treatments are beneficial, prescription treatments may be quicker acting and more efficacious in patients with moderate to severe disease or during flares. OTC agents are best used for maintenance between flares and to prevent progression of mild disease. Alternative and complementary treatments lack strong efficacy evidence. However, wet wraps, bleach baths, and other treatments appear to be promising when used in conjunction with conventional treatments. With the financial burden of atopic dermatitis ranging from 364 million to 3.8 billion dollars each year in the United States, we suspect this topic will gain further research attention.

The American Academy of Dermatology first published a series of guidelines for diagnosing and managing atopic dermatitis in 2014. Twelve clinicians were selected to review, grade, and offer clinical insight on available data regarding the clinical features, symptomology, pathophysiology, education, treatment, and emerging clinical studies on atopic dermatitis (AD). Based on these findings, the AAD released a guideline to streamline information on atopic dermatitis for physicians, recommending using clinical evidence to diagnose and first treating with nonpharmacologic therapies to restore the natural skin barrier. Topical pharmacologic therapies were recommended for improving pruritus and inflammation and newer systemic agents for clinically relevant moderate-to-severe cases. Evidence-based practices were emphasized in comparison to those that lacked therapeutic data. To highlight the emerging evidence and pharmacologic breakthroughs in atopic dermatitis, the AAD produced an updated set of guidelines educating physicians on new agents and their role in treatment. This chapter reviews the AAD guidelines as a tool for managing atopic dermatitis and staying up to date on disease advancements.

With recent advances in topical therapies for atopic dermatitis (AD), steroid-sparing options like calcineurin inhibitors, Janus kinase (JAK) inhibitors, and phosphodiesterase-4 (PDE-4) inhibitors are becoming mainstays in therapy, underscoring the importance of careful selection and usage of topical corticosteroids (TCSs) to minimize side effects. Alongside the necessity of emollient use, these steroid-sparing alternatives offer rapid itch relief and efficacy in improving disease severity. While TCSs still hold a prominent role in AD management, promising novel topical treatments like tapinarof and live biotherapeutics to modulate the skin microbiome are also discussed. Overall, the recent addition of novel topical therapies offers diverse options for AD management and underscores the importance of topical treatments in the management of AD.

OBJECTIVE: Emotions play an important role in consumers' perception of a sensory experience. The objective of this work was to investigate the ability of basic skin care formulas (i.e. without interference of odour, colour and packaging) and pillar ingredients (i.e. emollients and rheology modifiers) to elicit emotions. Another objective was to track, as claimed by neurocosmetics, the possible effect of formulas to trigger emotions from their direct biochemical effects on the skin. METHODS: Standard methodologies were mobilized, combining subjective and behavioural parameters (i.e. verbatim, prosody and gesture). Sense and Story methodology based on a collection of metaphoric verbatim was conducted after an induction phase. In addition, an experimental electrophysiological real-time visualization method was tried as a first experience in cosmetics. Finally, the ability of formulations with emotional benefits to modulate the release of neuropeptides by sensory neurons was evaluated on a 3D human model (epidermis co-cultured with sensory neurons). RESULTS: Skin care formulas were shown to play a role in emotional potential and the types of emotion generated, while changing one ingredient mostly acted on the intensity of the emotions. Verbatim provided contrasted answers depending on the protocol, highlighting the interest of non-verbal approaches to detect subtle effects. The in vitro model substantiated physiological effects of skin care formulas with emotional potential on human skin sensory neuron activity. CONCLUSION: Emotions were impacted by the change in ingredients and were better captured through non-verbal methods.
OBJECTIF: Les émotions jouent un rôle important dans la perception qu'ont les consommateurs d'une expérience sensorielle. L'objectif de ce travail était d'étudier la capacité de formules de soins pour la peau de base (c'estàdire sans interférence d'odeur, de couleur, d'emballage) et d' ingrédients essentiels (c'estàdire les émollients et les modificateurs de rhéologie) à susciter des émotions. Un autre objectif était de suivre, comme le prétendent les neurocosmétiques, l'effet possible des formules à déclencher des émotions à partir de leurs effets biochimiques directs sur la peau. MÉTHODES: Des méthodologies standards ont été mises en Åuvre, combinant des paramètres subjectifs et comportementaux (c'estàdire verbatim, prosodie et gestuelle). La méthodologie Sense & Story basée sur un ensemble de verbatim métaphoriques a été mise en Åuvre après une phase d'induction. En outre, une méthode expérimentale de visualisation électrophysiologique en temps réel a été testée comme première expérience dans le domaine des cosmétiques. Enfin, la capacité des formulations présentant des bénéfices émotionnels à moduler la libération de neuropeptides par les neurones sensoriels a été évaluée sur un modèle humain 3D (épiderme cocultivé avec des neurones sensoriels). RÉSULTATS: Il a été démontré que les formules de soins pour la peau jouent un rôle dans le potentiel émotionnel et les types d'émotions générées, tandis que le changement d'un ingrédient agit principalement sur l'intensité des émotions. Le verbatim a fourni des réponses contrastées selon le protocole, soulignant l'intérêt des approches non verbales pour détecter les effets subtils. Le modèle in vitro a confirmé les effets physiologiques des formules de soins pour la peau ayant un potentiel émotionnel sur l'activité des neurones sensoriels de la peau humaine. CONCLUSION: Les émotions ont été affectées par le changement d'ingrédients et ont été mieux saisies par des méthodes non verbales.

BACKGROUND: Recent discoveries have led to the suggestion that enhancing skin barrier from birth might prevent eczema and food allergy. OBJECTIVE: To determine the cost-effectiveness of daily all-over-body application of emollient during the first year of life for preventing atopic eczema in high-risk children at 2 years from a health service perspective. We also considered a 5-year time horizon as a sensitivity analysis. METHODS: A within-trial economic evaluation using data on health resource use and quality of life captured as part of the BEEP trial alongside the trial data. Parents/carers of 1394 infants born to families at high risk of atopic disease were randomised 1:1 to the emollient group, which were advised to apply emollient (Doublebase Gel or Diprobase Cream) to their child at least once daily to the whole body during the first year of life or usual care. Both groups received advice on general skin care. The main economic outcomes were incremental cost-effectiveness ratio (ICER), defined as incremental cost per percentage decrease in risk of eczema in the primary cost-effectiveness analysis. Secondary analysis, undertaken as a cost-utility analysis, reports incremental cost per Quality-Adjusted Life Year (QALY) where child utility was elicited using the proxy CHU-9D at 2 years. RESULTS: At 2 years, the adjusted incremental cost was £87.45 (95% CI -54.31, 229.27) per participant, whilst the adjusted proportion without eczema was 0.0164 (95% CI -0.0329, 0.0656). The ICER was £5337 per percentage decrease in risk of eczema. Adjusted incremental QALYs were very slightly improved in the emollient group, 0.0010 (95% CI -0.0069, 0.0089). At 5 years, adjusted incremental costs were lower for the emollient group, -£106.89 (95% CI -354.66, 140.88) and the proportion without eczema was -0.0329 (95% CI -0.0659, 0.0002). The 5-year ICER was £3201 per percentage decrease in risk of eczema. However, when inpatient costs due to wheezing were excluded, incremental costs were lower and incremental effects greater in the usual care group. CONCLUSIONS: In line with effectiveness endpoints, advice given in the BEEP trial to apply daily emollient during infancy for eczema prevention in high-risk children does not appear cost-effective.

BACKGROUND: New evidence has emerged since the 2014 guidelines that further informs the management of atopic dermatitis (AD) with topical therapies. These guidelines update the 2014 recommendations for management of AD with topical therapies. OBJECTIVE: To provide evidence-based recommendations related to management of AD in adults using topical treatments. METHODS: A multidisciplinary workgroup conducted a systematic review and applied the GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) approach for assessing the certainty of evidence and formulating and grading recommendations. RESULTS: The workgroup developed 12 recommendations on the management of AD in adults with topical therapies, including nonprescription agents and prescription topical corticosteroids (TCS), calcineurin inhibitors (TCIs), Janus kinase (JAK) inhibitors, phosphodiesterase-4 inhibitors (PDE-4), antimicrobials, and antihistamines. LIMITATIONS: The pragmatic decision to limit the literature review to English-language randomized trials may have excluded data published in other languages and relevant long-term follow-up data. CONCLUSIONS: Strong recommendations are made for the use of moisturizers, TCIs, TCS, and topical PDE-4 and JAK inhibitors. Conditional recommendations are made for the use of bathing and wet wrap therapy and against the use of topical antimicrobials, antiseptics, and antihistamines.

PURPOSE: To investigate the efficacy of a novel, multi-active emollient in preventing and managing acute radiation dermatitis (ARD) in breast cancer patients undergoing moderate hypofractionated (HF) radiotherapy (RT) compared to standard of care. METHODSA: A monocentric, open-label, randomized clinical trial (RCT) with breast cancer patients receiving moderate HF (dose: 40.05-55.86 Gy, fractions: 15-21) was conducted between January 2022 and May 2023. The experimental group received the novel emollient, while the control group received the standard skin care. Patients applied the skin care products twice daily during the complete RT course. The primary outcome was the severity of ARD at the final RT session measured by the modified Radiation Therapy Oncology Group (RTOG) criteria. Secondary outcomes included patient symptoms, quality of life (QoL), and treatment satisfaction. RESULTS: A total of 100 patients with 50 patients per group were enrolled. In the control group, 50% of the patients developed RTOG grade 1 ARD and 48% grade 2 or higher, while in the experimental group, the severity of ARD was significantly lower with 82% grade 1 and 16% grade 2 ARD (P = .013, χ2-test). The frequency and severity of xerosis were significantly lower in the experimental compared to the control group (Ps ≤ .036, Mann Whiney U test). The impact of ARD on the QoL was low, and treatment satisfaction was high in both groups, with no significant difference. CONCLUSION: This RCT shows that the novel, multi-active emollient significantly reduced the ARD RTOG grade. Research in a more diverse patient population is warranted. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04929808 (11/06/2021).

BACKGROUND: Tattoo aftercare instructions describe how to care for a new tattoo. Unfortunately, tattoo artists often base their advice on personal experience rather than best practices in medical wound management. The diversity of recommendations in these instructions is currently unknown. OBJECTIVES: Our review was performed to determine current recommendations in tattoo aftercare instructions in the United States. METHODS: Using a Google search, a total of 700 aftercare instructions from all 50 states and Washington D.C. were collected and their contents analyzed. RESULTS: Most instructions encouraged washing new tattoos with antibiotic soaps, including chlorhexidine, and 14.9% encouraged using topical antibiotics. Few instructed individuals to wash their hands before touching a healing tattoo. A total of 70 moisturizers were recommended. Of these, 22 were niche products made specifically for tattoo aftercare. Only a subset of instructions provided parameters about when to contact the tattooist (49.9%) and/or a physician (19.4%) should there be a complication in the healing process. CONCLUSION: The content and recommendations of the 700 instructions vary tremendously. Many lacked instructions on appropriate hygiene and when to seek medical care. As skin and wound care experts, there may be an opportunity for the dermatology community to partner with tattooists to create more useful evidence-based tattoo aftercare practices.

OBJECTIVE: To observe the effect of niacinamide-containing body emollients combined with a cleansing gel on the clinical symptoms of mild atopic dermatitis (AD) in adults. METHODS: From July 2022 to January 2023, adults with mild AD were enrolled at Huashan Hospital Affiliated to Fudan University using single-center, randomized and placebo-controlled methods. They were divided into three groups: the control group, treatment group 1 (T1) receiving niacinamide-containing body emollients alone, and treatment group 2 (T2) receiving emollients plus niacinamide-containing cleansing gel. All patients were orally administered 10 mg of ebastine tablets daily. AD severity (SCORAD score), peak pruritus numeric rating scale (PP-NRS), patient-oriented measure of eczema (POEM), dermatological quality of life index (DLQI) score, transepidermal water loss (TEWL), and stratum corneum water content (SCWC) were measured by the same dermatologist at days 0, 7, 14, and 28. RESULTS: A total of 122 patients were enrolled, including 38 in the control group, 42 in the T1 group and 42 in the T2 group. There were no obvious adverse reactions at the end of the study and the clinical scores and stratum corneum barrier of all the groups improved significantly relative to baseline. The SCORAD, PP-NRS, DLQI, TEWL and SCWC scores in T1 group (12.43 ± 3, 3.3 ± 0.9, 7.1 ± 2.33, 17.1 ± 9.12, 67.2 ± 21.46, seperately) and T2 group (11.17 ± 3.26, 3 ± 1.3, 6.5 ± 2.11, 16.3 ± 9.12, 69.4 ± 24.52, seperately) were significantly improved than the control group(15.1 ± 3.64, 4.3 ± 1.7, 9.5 ± 2.46, 21.2 ± 9.47, 52.7 ± 22.43, seperately) at the endpoint of the study, while compared the POEM scores, only T2 group showed the difference with control group (5.2 ± 1.4 vs. 6 ± 1.6). The epidermal barrier parameters of TEWL and SCWC in the T2 group (17.57 ± 5.24, 66.46 ± 21.38, seperately) were significantly better than that of the T1 (19.96 ± 4.45, 56.45 ± 20.48, seperately) and control group(21.89 ± 7.03, 51.56 ± 16.58, seperately) on the 14th day of follow-up. CONCLUSION: The use of niacinamide-containing body emollients can significantly improve the clinical symptoms, quality of life, and skin barrier function in patients with mild AD. The addition of niacinamide-containing cleansing gel can also affect the clinical efficacy at certain time points.

BACKGROUND: Moisturizers are first-line therapy for treatment of atopic dermatitis (AD). Although there are multiple types of moisturizers available, head-to-head trials between different moisturizers are limited. OBJECTIVE: To evaluate if a paraffin-based moisturizer is as effective as ceramide-based moisturizer in children with AD. MATERIALS AND METHODS: In this double-blind, randomized comparative trial of pediatric patients with mild to moderate AD, subjects applied either a paraffin-based or ceramide-based moisturizer twice daily. Clinical disease activity using SCOring Atopic Dermatitis (SCORAD), quality of life using Children/Infants Dermatology Life Quality Index (CDLQI/IDLQI), and transepidermal water loss (TEWL) were measured at baseline and at follow-up at 1, 3, and 6 months. RESULTS: Fifty-three patients were recruited (27 ceramide group and 26 paraffin group) with a mean age of 8.2 years and mean disease duration of 60 months. The mean change in SCORAD at 3 months in the ceramide-based and paraffin-based moisturizer groups was 22.1 and 21.4, respectively (p = .37). The change in CDLQI/IDLQI, TEWL over forearm and back, amount and days of topical corticosteroid required, median time to remission and disease-free days at 3 months were similar in both groups. As the 95% confidence interval (CI) of mean change in SCORAD at 3 months in both groups (0.78, 95% CI: -7.21 to 7.52) was not within the predefined margin of equivalence (-4 to +4), the conclusion of equivalence could not be proven. CONCLUSION: Both the paraffin-based and ceramide-based moisturizers were comparable in improving the disease activity in children with mild to moderate AD.

PURPOSE: Environmental factors such as bathing may play a role in atopic dermatitis (AD) development. This analysis utilized data from the Community Assessment of Skin Care, Allergies, and Eczema (CASCADE) Trial (NCT03409367), a randomized controlled trial of emollient therapy for AD prevention in the general population, to estimate bathing frequency and associated factors within the first 9 weeks of life. METHODS: Data were collected from 909 parent/newborn dyads recruited from 25 pediatric and family medicine clinics from the Meta-network Learning and Research Center (Meta-LARC) practice-based research network (PBRN) consortium in Oregon, North Carolina, Colorado, and Wisconsin for the CASCADE trial. Ordinal logistic regression was used to conduct a cross-sectional analysis of the association between bathing frequency (measured in baths per week) and demographic, medical, and lifestyle information about the infant, their family, and their household. Variables were selected using a backwards-stepwise method and estimates from the reduced model are reported in the text. RESULTS: Moisturizer use (OR = 2.03, 95% CI: 1.54-2.68), Hispanic or Latino ethnicity (OR = 1.97, 95% CI: 1.42-2.72), a parental education level lower than a 4-year college degree (OR = 2.48, 95% CI: 1.70-3.62), living in North Carolina or Wisconsin (compared to Oregon; OR = 2.12 and 1.47, 95% CI: 1.53-2.93 and 1.04-2.08, respectively), and increasing child age (in days; OR = 1.02, 95% CI: 1.01-1.02) were significantly associated with more frequent bathing, while pet ownership (OR = 0.67, 95% CI: 0.52-0.87) was significantly associated with less frequent bathing. CONCLUSIONS: We found significant ethnic, geographic, and socioeconomic variation in bathing frequency before 9 weeks of age that may be of relevance to AD prevention studies.

BACKGROUND: the potential fire risk of fabrics impregnated with emollients has been described within the health service, including ignition of bandages. The role of emollients in fire fatalities have also been included in coroner reports, as accelerating fires when present. AIMS: although changes in burning behaviour is known, no standard tests have been carried out on bandages which are often used in conjunction with emollients. METHOD: using a standard vertical flammability test, the flammability of viscose bandage was compared to when impregnated with nine dried on emollients with low to high and non-paraffin content. FINDINGS: the time to ignition was significantly reduced with an emollient present and the glowing time was longer. CONCLUSIONS: the same safety advice applies to viscose bandages as other fabrics with emollients; do not expose them to naked flames or high heat sources or allow emollients to build up on bandages.

Introduction: Food allergy is a common concomitant disease in patients with atopic dermatitis. Sensitisation and subsequent development of food allergy might result from the application of skincare products containing food allergens, particularly when the skin barrier is impaired and inflamed. Emollients are the mainstay of the management of atopic dermatitis; however, the prevalence of food allergens in skincare products used for atopic dermatitis is unknown. Aim: To analyse the prevalence of major food allergens in skincare products for atopic dermatitis. Material and methods: Three major online cosmetic retailers in Poland were screened for atopic skincare products. The major food allergens under the mandatory allergen labelling regulation of the European Union were searched for using the INCI nomenclature of cosmetics ingredients. Results: We screened 396 skincare products, out of which 127 (32.1%) products contained at least one derivative of a major food allergen. The most common allergens were almonds, macadamia nuts, soya and cereals, followed by sesame and milk. There was no significant difference in the presence of food derivatives between leave-on and rinse-off skincare products, as well as between those intended for use by infants and children, and adults only. Conclusions: Our analysis revealed that major food allergens are prevalent in skincare products for eczema. Applying skincare products containing food derivatives on affected and inflamed skin can promote percutaneous sensitisation. Therefore, clinicians and patients with atopic dermatitis must be careful of products used for treating eczema that may contain derivatives of a major food allergen.
RESUMO
BACKGROUND: Atopic dermatitis (AD) is a chronic skin disease characterized by dry skin, severe itching, inflammation and impaired quality of life. Moisturizing is an integral part of treatment for AD, but its potential for prevention of AD is unclear. OBJECTIVE: To evaluate whether the early use of emollients in infancy can prevent later development of AD. METHODS: We searched Medline, Embase, Web of Science, PubMed, Cochrane Library and other databases to collect randomized controlled trials on early use of emollients in infants for a meta-analysis. RESULTS: Nine articles were included. The OR value for incidence rate was 0.7 (95% CI: 0.48-1.01). No significant publication bias was found by Egger's test. The sensitivity analysis indicated that the final conclusion was reliable. CONCLUSIONS: We found that the difference in incidence rate of AD between the experimental and control groups was not statistically significant. However, due to different methods of using emollients, different follow-up times and different sample sizes included in this meta-analysis, a definitive conclusion could not be reached in this study. In the future, it is still necessary to carry out randomized controlled, multicenter, large-sample trials with an excellent study design and high methodological quality on early application of emollients in high-risk infants to prevent AD.

A suitable immobilized lipase for esters syntheses should be selected considering not only its cost. We evaluated five biocatalysts in syntheses of octyl caprylate, octyl caprate, and octyl laurate, in which conversions higher than 90% were achieved. Novozym®ï»¿ 435 and non-commercial preparations (including a dry fermented solid) were selected for short-term octyl laurate syntheses using different biocatalysts loadings. By increasing the biocatalyst's loading the lipase's reusability also raised, but without strict proportionality, which resulted in a convergence between the lowest biocatalyst loading and the lowest cost per batch. The use of a dry fermented solid was cost-effective, even using loadings as high as 20.0% wt/wt due to its low obtaining cost, although exhibiting low productiveness. The combination of biocatalyst's cost, esterification activity, stability, and reusability represents proper criteria for the choice. This kind of assessment may help to establish quantitative goals to improve or to develop new biocatalysts.

Atopic dermatitis (AD) is the most common chronic inflammatory skin disease and significantly impacts patients' lives, particularly in its severe forms. AD clinical presentation varies over the course of the disease, throughout different age groups, and across ethnicities. AD is characterized by a spectrum of clinical phenotypes as well as endotypes. Starting from the current description of AD pathogenesis, this review explores the rationale of approved AD therapies from emollients to biologicals and introduces novel promising drugs.

BACKGROUND: Guidelines generally recommend an adjuvant treatment with emollients for patients suffering from psoriasis. However evidence for this purpose is limited. PATIENTS AND METHODS: We performed a prospective observational study with an emollient containing 10% urea, ceramides, glycerin and glyceryl glucoside in patients suffering from mild to moderate psoriasis. The patients had to be stable for at least 12 weeks on prior antipsoriatic therapy including topical therapy, systemic treatment or phototherapy which was continued during the trial. RESULTS: A 4-week daily application of the emollient resulted in significant improvement regarding quality of life (measured by DLQI, Dermatology Life Quality Index) and clinical outcome (measured by local PASI, Psoriasis Area and Severity Index) among the treated patients. CONCLUSION: The trial results show that a daily adjuvant treatment with emollients can support a basic antipsoriatic therapy both in aspects of clinical efficacy and quality of life in mild to moderate patients suffering from psoriasis.

Emollients are acknowledged as a part of standard care in therapeutic and prevention protocols as well as a part of everyday skin care routine. When it comes to making a final decision between two emollient products, the ingredient list, that is, the formulation composition could be the determining factor. In such cases the consumer, and some healthcare providers, believe that products with the same qualitative composition (ingredient list) must have the same efficacy. In this study, we have investigated the skin hydration performance of two emollient preparations (DBG and MBG), which appear to contain the same ingredients, and hence, could be considered interchangeable in everyday practice. Our studies showed that the effects of DBG were overall superior to the ones attributed to MBG at each investigated time point (1, 2, 4, and 24 h post application) when tested on normal and dry skin. Consequently, it is shown that two apparently qualitatively identical products do not necessarily provide matching efficacy.
