As we grow older, we start to lose calcium and bone and under the skin are fat pads which lessen. Two protein strands elastin anc collagen are produced at lesser quantity. Those wrinkles come about because without enough of these two proteins the skin is not as smoot h and elastic as it once was and therefore sags. A product named AHA causes stimulation of mucin, which is a substance that fills in between collagen fibers. Over the counter creams with AHA help remove the outer layer of skin which has become dried and has damaged cells
Botox when injected prevents the muscles from moving and therefore wrinkles are stopped. Wrinkles disappear for about four months. Not enough studies have been done to determine the long term effects of this treatment.
90% of all skin changes associated with ageing are really the result of sun exposure. Smokers are five times more likely to have wrinkles. Smoking reduces the blood supply and oxygen to the skin and it may affect collagen and elastin. Fast weight loss will be very noticeable as sagging skin in the face. Exercise works because it relieves stress and increases blood supply. Moisturizers will keep the skin from dehydrating although they will not lessen wrinkles.
