RESUMO
Acne should not be perceived as a self-limiting affliction of adolescence. Due to the growing problem of antimicrobial-resistant bacteria, restrictive use of peroral and topical antibiotics is recommended. There are a number of effective agents for topical treatment of mild to moderate acne. In cases of severe, therapy-resistant acne, treatment with peroral isotretinoin is recommended.

BACKGROUND: Tattoos with henna colours have become very popular and the prevalence of contact allergy seems to increase. MATERIAL AND METHODS: This is a short review article based on our own clinical experience and literature identified through a search in PubMed with the words "henna", "paraphenylendiamin" and "allergic contact dermatitis." A case report is included. RESULTS: It is well documented that many experience skin reactions after henna tattoos. The cause is almost always contact allergy to the azo compound paraphenylendiamin, which is added to speed up the process and make the colour darker. Most people, including children, get henna tattoos during vacations in Asia or the Mediterranean. Established contact allergy is permanent. Many hair-colour products contain paraphenylendiamin, and persons with contact allergy against the product may develop a very strong contact allergic eczema by use of such substances. Acute reactions are treated with local cortisone products, or with systemic steroids. Cross reaction to substances with a similar chemical structure may occur. INTERPRETATION: Tattoos with paraphenylendiamin-containing henna colours should be avoided.
