This study, based on a representative sample of the American population, reveals a high prevalence of sensitive skin in the USA. Sensitive skin is mainly associated with dry skin, fair phototype, reactivity to climatic and environmental factors, and cosmetics. American dermatologists seem largely involved in the care of this condition.

Introduction: The ECCA grading scale (échelle d’évaluation clinique des cicatrices d’acné) is a tool designed to help dermatologists to assess the severity of acne scars and to standardize the discussions about the treatments of scars. Methods: We developed an acne scar clinical grading scale called ECCA, which consists of 6 items designed to assess easily and quickly the severity of acne scars by a global score. The interobserver reliability of the ECCA grading was statistically validated. Results: The statistical analysis showed the interinvestigator reliability of the ECCA grading scale among 7 dermatologists who used it on the same group of 10 acne patients. Conclusion: ECCA is a new tool which will now be available for dermatologists to use in their everyday practice and for clinical trials evaluating the efficacy of treatments on acne scars.

Avène Thermal Spring Water (TSW) is a natural active component characterized by a low mineral content. In vitro experiments have demonstrated the effect of Avène TSW on membrane fluidity, its antiradical and anti-inflammatory properties, its effects on many mediators involved in the immune response and its stimulating effect on keratinocyte differentiation. The clinical efficacy of the water was demonstrated at the hydrotherapy centre in chronic and disabling diseases such as atopic dermatitis but also in various settings in medical and post dermatology procedure such as photodynamic therapy or photothermolysis. All these data support the fact that the Avène TSW is an active component.

This study is the first observational study in such a large cohort demonstrating the benefit of a 3-week treatment at the Avène Hydrotherapy Centre for atopic and psoriatic patients.

These data show that a combination of RAL 0.1% and GA 6% may be used in association with other topical anti-acne treatments with an excellent tolerance.
