Effect of glycolic acid, phytic acid, soothing complex containing Emulsion on Hyperpigmentation and skin luminosity: A clinical evaluation.

BACKGROUND

Improvement in skin luminosity and dyschromia such as postinflammatory hyperpigmentation (PIH) and actinic photodamage are leading causes for cosmetic consultation. Formulation of topical at home treatment is challenging, using a range of modalities, to help hinder or prevent inflammatory mediators without further irritating the skin. Glycolic acid is a known antioxidant; in various free acid levels, it has been introduced as a topical therapy aimed at reducing pigmentation and improving skin texture, tone, and luminosity.

METHODS

In a 12-week clinical study, a novel, topical facial emulsion containing 10% glycolic acid, 2% phytic acid, and soothing complex in emulsion was evaluated for its effectiveness in treating skin quality in American female volunteers with Fitzpatrick skin types II-VI. Efficacy evaluations were performed at pretreatment baseline, weeks 2, 4, 8, and 12, and included expert clinical grading, and self-assessment questionnaires. Cutaneous tolerability was also evaluated by assessing subjective and objective irritation of the treatment area.

RESULTS

Significant improvement in the appearance of skin PIH, hyperpigmentation, texture, and tone homogeneity was observed beginning at week 4 and continued through week 12.

CONCLUSIONS

The findings suggest that the test product is well suited for at-home skincare. It was both well-tolerated and an effective treatment option for addressing hyperpigmentation and overall skin luminosity.
