Evaluation of skin moisture, sebum, and skin elasticity in dry and oily skin types after glycolic acid peel
Hee-Kyung Kong, In-chul Hwang
ABSTRACT
A glycolic acid peel is the typical one of chemical peels used to improve and smooth the texture of the facial skin using a chemical solution such as natural fruit acids. Glycolic acid is one of alpha hydroxy acids(AHAs) to remove old, dead, and sun-damaged surface skin cells, and promote healthier and softer skin. This study was conducted to evaluation the improvement effects in skin moisture, sebum(oiliness) and elasticity for dry and oily skin types after glycolic acid treatment. The 20 young ladies of 21.0±5.2 years old were assigned to two group according to their dry or oily skin types. And then skin moisture, sebum and elasticity in T-zone(forehead) and U-zone(cheek) using a non-invasive measuring method were measured after a glycolic acid peel treatment a week for 4 weeks. The results were as follows: 1. The sebum content of T- and U-zone in dry skin group showed a significant increase with increasing glycolic acid peel treatments, while in oily skin group it was significantly decreased (p<0.05). 2. The moisture content of T- and U-zone in dry skin and of U-zone in oily skin group was increased with increasing glycolic acid peel treatments. But the moisture content of T-zone did not show significant difference according to repeated chemical peel treatments (p>0.05). 3. The elasticity content of T-zone and U-zone in dry skin group and of T-zone in oily skin group was significantly increased according to repeated chemical peel treatments. But the elasticity content of U-zone in oily skin group did not show according to repeated chemical peel treatments (p>0.05).
