At what age does the skin start to get noticeable wrinkles?

Skin aging. Intrinsic aging is the natural aging process that takes place over the years regardless of outside influences. After the age of 20, a person produces about 1 percent less collagen in the skin each year. As a result, the skin becomes thinner and more fragile with age. There is also diminished functioning of the sweat and oil glands, less elastin production, and less gag formation.
Wrinkles on skin. There is no fixed age foe wrinkles to start.It depends on your genes, your race, your exposure over the years to sun, your diet and of course your age.Every body will get wrinkles if you live long enough and it isnatural part of aging but when you start with wrinkles varies.
