To instrumentally evaluate the efficacy and the safety of a new ternary system chemo exfoliating formulation (water-dimethyl isosorbide-acid) vs traditional binary systems (water and acid) where the acid is maintained in both the systems at the same concentration. Different peelings (binary system pyruvic acid and trichloroacetic acid-TCA, and ternary system pyruvic acid and TCA) were tested on the volar forearm of 20 volunteers of both sexes between 28 and 50 years old. The outcomes were evaluated at the baseline, 10 minutes, 24 hours, and 1 week after the peeling by means of noninvasive skin diagnosis techniques. In vivo reflectance confocal microscopy was used for stratum corneum evaluation, transepidermal waterloss, and Corneometry for skin barrier and hydration, Laser Doppler velocimetry in association with colorimetry for irritation and erythema analysis. The instrumental data obtained showed that the efficacy and safety of the new ternary system peel compounds were significantly higher compared with the binary system formulations tested. The new formulation peels improved chemexfoliation and reduced complications such as irritation, redness, and postinflammatory pigmentation compared to the traditional aqueous solutions. The study showed that ternary system chemexfoliation, using a controlled delivery technology, was able to provide the same clinical effects in term of stratum corneum reduction with a significantly reduced barrier alteration, water loss, and irritation/erythema compared to traditional binary system peels. © 2017 Wiley Periodicals, Inc.

Full Text Available Chemical peeling or chemexfoliation has become increasingly popular in recent years for treatment of a number of cosmetic skin problems. Topical glycolic acid in the concentration of 10-30% for 3-5 minutes at fortnightly intervals was investigated as a therapeutic peeling agent in 41 patients having acne (39%, melasma (36.5%, post inflammatory hyperpigmentation (12% and superficial scarring of varied etiology (12%. A final evaluation done at 16 weeks revealed that this modality is useful especially in superficial scarring and melasma, moderately successful in acne patients with no response in dermal pigmentation. No significant untoward effects were seen.
