The Biology
Elasticity is the skin’s ability to stretch and rebound, supported by elastin fibers and the collagen scaffold. As these decline with age and UV exposure, skin becomes less firm and more prone to visible lines.
Key Factors
UV radiation is the largest modifiable factor, degrading elastin and collagen. Smoking, poor sleep, and stress also contribute. Sun protection, adequate sleep, and consistent routines are the most effective educational approaches.
