Abstract EN
Facial skin ageing is caused by intrinsic and extrinsic mechanisms.
Intrinsic ageing is highly related to chronological age.
Age related skin changes can be measured using clinical and biophysical methods.
The aim of this study was to evaluate whether and how clinical characteristics and biophysical parameters are associated with each other with and without adjustment for chronological age.
Twenty-four female subjects of three age groups were enrolled.
Clinical assessments (global facial skin ageing, wrinkling, and sagging), and biophysical measurements (roughness, colour, skin elasticity, and barrier function) were conducted at both upper cheeks.
Pearson’s correlations and linear regression models adjusted for age were calculated.
Most of the measured parameters were correlated with chronological age (e.g., association with wrinkle score, r = 0.901 ) and with each other (e.g., residual skin deformation and wrinkle score, r = 0.606 ).
After statistical adjustment for age, only few associations remained (e.g., mean roughness ( R z ) and luminance ( L * ), β = - 0.507 , R 2 = 0.377 ).
Chronological age as surrogate marker for intrinsic ageing has the most important influence on most facial skin ageing signs.
Changes in skin elasticity, wrinkling, sagging, and yellowness seem to be caused by additional extrinsic ageing.
