The Effects of a Daily Skincare Regimen on Maintaining the Benefits Obtained from Previous Chemical Resurfacing Treatments.

BACKGROUND: Chemical peels are versatile treatments that involve chemical exfoliation of the skin for cosmetic improvement. Deeper peels produce more significant results, but can be associated with longer healing time and potential complications. Novel chemical resurfacing treatments (AGE and MELA) were developed in Europe to produce skin resurfacing via controlled inflammation to promote cell regeneration with minimum negative effects associated with conventional peelings. The AGE Resurfacing regimen is indicated for the treatment of photoaging, and consists of multi-ingredient peeling solution with trichloroacetic acid, pyruvic acid, salicylic acid, mandelic acid, and lactobionic acid. The MELA Resurfacing regimen addresses hyperpigmentation concerns and contains mandelic acid, potassium azeloyl diglycinate, retinol, salicylic acid, phytic acid, lactobionic acid, and lactic acid. Results of previously conducted US clinical experience trial of AGE and MELA resurfacing protocols rated 81% of subjects with some level of improvement according to physician assessment.
OBJECTIVES: To evaluate whether a daily skin care regimen used for 12 weeks could maintain the benefits achieved with AGE and MELA chemical resurfacing treatments.
METHODS: Subjects who completed participation in the AGE and MELA skin resurfacing clinical trial were recruited to participate in a continuation trial and used a daily regimen of MDRejuvena facial products for 12 weeks. No other facial products were permitted. Physicians assessed the severity of individual skin parameters at baseline and week 12 and provided global assessment. Subjects assessed improvement of individual skin parameters at week 12 and provided an overall assessment.
RESULTS: Thirteen subjects participated in the 12-week continuation trial. According to the physician's global assessment, all subjects demonstrated some level of improvement at week 12 compared to baseline. Physician assessment showed a decrease in severity of all skin parameters assessed at week 12 compared to baseline. According to the subject overall assessment at week 12, 11 of 12 subjects noted some level of improvement, 1 subject saw no improvement, and 1 subject did not provide an overall assessment. Mild to moderate improvement was observed by subjects in all individual skin parameters assessed except for skin discoloration.
CONCLUSIONS: The results of the continuation study demonstrate that use of a daily skin care regimen, which include combination of 2 various strengths of MDRejuvena Rejuvaphyl® Rejuvenating Complex: low strength (LS) and high strength (HS), not only maintains but can enhance the beneficial effects of skin resurfacing treatments for at least 12 weeks.

Multicenter evaluation of a topical antioxidant serum.

BACKGROUND: A new antioxidant serum has been formulated with sodium ascorbate, a sodium salt of Vit C, which aims to address facial photodamage while maintaining a low irritation profile and preserving elastin. Detailed background science has been submitted in a previous publication. This open-label study was conducted to validate the science by demonstrating product efficacy and tolerability in patients with moderate to severe facial photodamage. METHODS: A multicenter, open-label clinical study was undertaken over 5 months from March 2023 to July 2023. Thirty six eligible participants (35 female, 1 male), aged 38-69 years, and Fitzpatrick skin types II-V were enrolled into and completed the study following 12 weeks of the topical antioxidant serum use twice daily, along with the following supporting products (gentle cleanser, moisturizer, and sunscreen for as needed use). Follow-up visits were conducted in Weeks 2, 4, 8, and 12. At every visit, participants were evaluated for facial photodamage severity and test product tolerability. Additionally, study participants underwent subject assessments and satisfaction questionnaires, investigator assessments, biopsy collection, and photography. RESULTS: Significant improvements in all evaluated facial photodamage parameters were observed at 12 weeks together with excellent tolerability and subject satisfaction persisting to Week 12 at study completion. Histology most notably revealed increased elastin fibers in 5 out of 5 post 12-week treatment biopsies on Movat staining, while Herovici stains revealed stimulation of collagen and early formation of new fibers. CONCLUSION: A novel antioxidant serum has demonstrated to be safe and effective for addressing facial photodamage, while stimulating the production of both elastin and collagen in the extracellular matrix (ECM).

Assessment of a superficial chemical peel combined with a multimodal, hydroquinone-free skin brightener using in vivo reflectance confocal microscopy.

The combination of in-office procedures such as chemical peels with topical maintenance therapies has been shown to provide greater efficacy than either treatment by itself in the management of melasma. A series of 3 case studies were conducted to evaluate the efficacy and tolerability of one superficial chemical peel (containing a proprietary blend of resorcinol, lactic acid, salicylic acid, and retinol) combined with a topical multimodal, hydroquinone-free skin brightener as postpeel maintenance therapy. Patients presented with moderate to severe facial hyperpigmentation. At baseline, subjects received the superficial chemical peel treatment followed by a standard postpeel skin care regimen (cleanser, moisturizer, and SPF 30+ sunscreen). Approximately 1 week after the peel procedure, subjects initiated twice-daily application of the skin brightener. Subjects were then evaluated for Global Improvement in Hyperpigmentation by the investigator for up to 7 weeks postpeel. Standardized digital photographs of the subjects facial skin and in vivo reflectance confocal microscopy (RCM) images were taken of a target hyperpigmented lesion at baseline and at follow-up. Standardized photography and in vivo RCM images at baseline and at postpeel show the improvements observed by the investigator. Results from these case studies suggest that the combination of a superficial chemical peel with topical maintenance and the multimodal skin brightener may provide an effective treatment approach for subjects with moderate to severe facial hyperpigmentation.

Global periorbital skin rejuvenation by a topical eye cream containing low molecular weight heparan sulfate (LMW-HS) and a blend of naturally derived extracts.

BACKGROUND: Maintaining a youthful appearance is a priority for many people. Global eye rejuvenation is sought more frequently and at a younger age than other treatments. Major concerns around the eye area are periorbital hyperpigmentation, puffiness, and lines and wrinkles. Glycosaminoglycans (GAGs) are complex carbohydrates that modulate skin health, repair and renew skin's appearance. Heparan sulfate (HS) is the most biologically active GAG, although it is too large and polar to penetrate the skin. Low Molecular Weight Heparan Sulfate (LMW-HS) is a smaller version of HS designed for skin penetration while preserving its activity. In this study, we investigated the effects of a topical eye cream containing LMW-HS and a blend of naturally derived extracts to address global periorbital rejuvenation. METHOD: A single-center, open-label study including female and male subjects (n = 15) was conducted to evaluate the efficacy and tolerability of an eye cream containing LMW-HS and a blend of naturally derived extracts applied twice daily for 12 weeks. RESULTS: Improvements in the appearance of periorbital hyperpigmentation and fine and coarse wrinkles were observed as early as week 2 with continuous improvement up to 12 weeks. Decrease in puffiness (73%) and dark circles (93%) were reported by subjects. The test product was highly rated by subjects on performance and attributes and was well tolerated by all the subjects in this study. CONCLUSION: Results demonstrated that an eye cream containing LMW-HS and a blend of naturally derived extracts achieved global skin rejuvenation by improving appearance of periorbital hyperpigmentation, puffiness, and fine and coarse wrinkles.

Topical Treatment of Aging Hands: Brief Report.

Rejuvenation of aging hands is becoming increasingly important to physicians and their patients. While a variety of invasive treatments are available, topical products that improve manifestations of aging hands are needed. In this brief report, the efficacy of a topical product containing urea, lipids, sodium copper chlorophyllin complex, antioxidants, and humectants was assessed in subjects with moderate-to-severe photodamage of the hands.
