研究概览
简要总结
This study investigates whether skin hydration levels are related to how old the skin looks. Thirty women aged 30 to 60 years will attend a single visit at a licensed esthetic practice in Florida. Skin moisture will be measured at seven points on the face using the BT-Analyze device. Photographs will be taken and evaluated by a blinded expert cosmetologist using a standard aging scoring system. The study will determine whether women with lower skin hydration tend to show more visible signs of aging.
详细描述
Skin hydration is maintained through hyaluronic acid, natural moisturizing factor (NMF), and the lipid barrier of the stratum corneum. Dehydration activates matrix metalloproteinases (MMPs) which degrade collagen and elastin, accelerating visible aging. This cross-sectional observational study will enroll 30 women in three age groups (30-40, 40-50, and 50-60 years). Hydration will be assessed using BT-Analyze across seven facial zones. The primary outcome is the Spearman rank correlation between mean hydration score and modified Glogau visual aging score (0-18 points). Covariates include age, Fitzpatrick skin type, daily water intake, menopausal status, and skincare habits.
