Background:
Dry skin, caused by improper care or genetic conditions, can affect people of all ages. Skin hydration is determined its lipid content, which inhibits water loss from the epidermis, as well as other substances such as polyhydroxy acids and gluconolactone that can bind water. The aim of this study was to evaluate skin hydration after the application of 10% and 30% gluconolactone solution in a split face model.
Materials And Methods:
Sixteen healthy women were qualified for the study. Three split face treatments were performed, with 10% and 30% gluconolactone solution applied to two sides of the face. Skin moisture was measured before each treatment and a week after the last treatment at three measurement sites on either side of the face, that is, on the forehead, around the eye and on the cheek.
Results:
Corneometric measurements showed a significant increase in facial skin hydration after gluconolactone treatment. No significant differences were observed between the application of 10% and 30% solution.
Conclusion:
Gluconolactone is a moisturizing substance which works well in dry skin care.
