Under-eye skin laxity refers to loose, thinning, or crepey skin beneath the eyes, typically caused by aging, collagen breakdown, and environmental factors. The skin under the eyes is naturally thinner than the rest of the face, making it more susceptible to sagging, fine lines, and textural changes over time. Dehydration, sun exposure, and lifestyle choices can further contribute to the loss of elasticity in this delicate area. While this condition is common, advanced aesthetic treatments can tighten and rejuvenate the under-eye skin, restoring a more refreshed, youthful look.
