A bioengineering study on the efficacy of a skin protectant lotion in preventing SLS-induced dermatitis.

BACKGROUND/AIMS: This study evaluated the efficacy of a dimethicone skin protectant lotion against sodium lauryl sulfate (SLS)-induced irritant contact dermatitis (ICD) by clinical visual grading and bioengineering techniques in 12 healthy humans. METHODS: The flexor aspects of both forearms of the subjects were used as test sites. Each test was duplicated to diminish the variations of the test sites.
