What are they? Wrinkles are caused by a loss of collagen and elastin — the tissues in the skin that make it firm and elastic — as we age. The degree of wrinkling depends on your genetic makeup, but smoking, dry skin and sun exposure (especially sunburns) make it worse. Dynamic motion — making facial expressions — also causes permanent creases over time.
Treatment
Tretinoin (Retin-A ), other retinoids.
Laser resurfacing. This process burns away the outer layer of skin, bringing a less wrinkled layer to the surface.
Alpha hydroxy acids (AHAs). These slough off dead skin cells and stimulate collagen production, making cells look plumper.
Collagen injections.
Chemical peels.
Botox injections.
Fat transfer. Fat is taken out of the buttocks and injected into the creases in the face.
