The effects of a daily facial lotion containing vitamins B3 and E and provitamin B5 on the facial skin of Indian women: a randomized, double-blind trial.
BACKGROUND
The B vitamins niacinamide and panthenol have been shown to reduce many signs of skin aging, including hyperpigmentation and redness.


OBJECTIVE
To measure the facial skin effects in Indian women of the daily use of a lotion containing niacinamide, panthenol, and tocopherol acetate using quantitative image analysis.


METHODS
Adult women 30-60 years of age with epidermal hyperpigmentation were recruited in Mumbai and randomly assigned to apply a test or control lotion to the face daily for 10 weeks. Effects on skin tone were measured using an image capturing system and associated software. Skin texture was assessed by expert graders. Barrier function was evaluated by transepithelial water loss measurements. Subjects and evaluators were blinded to the product assignment.


RESULTS
Of 246 women randomized to treatment, 207 (84%) completed the study. Women who used the test lotion experienced significantly reduced appearance of hyperpigmentation, improved skin tone evenness, appearance of lightening of skin, and positive effects on skin texture. Improvements versus control were seen as early as 6 weeks. The test lotion was well tolerated. The most common adverse event was a transient, mild burning sensation.


CONCLUSIONS
Daily use of a facial lotion containing niacinamide, panthenol, and tocopheryl acetate improved skin tone and texture and was well tolerated in Indian women with facial signs of aging.
