“…Intrinsic changes occur as the skin and subcutaneous tissues age over time and are due to soft tissue volume loss from fat atrophy, gravity-induced soft tissue redistribution, and a reduction in facial skeletal support. 4,5 Extrinsic skin aging results from chronic sun exposure and typically manifests in the form of wrinkles, lentigines, keratoses, mottled pigmentation, telangiectasia, loss of translucency, decreased elasticity, textural roughness, and sallow color. 6,7 The main determinant of skin aging is not intrinsic changes but photodamage, 6 but not all aging skin is equal.…”
