A number of skin changes occur as we age. Skin is replaced every three weeks at age 20 but this increases to every nine weeks by age 50, so in return, the rate of skin cell replacement is reduced producing a thinner, more fragile skin.
Damaged proteins, which are the results of scars, oxidative damage, sun damage and cross-linking of skin proteins by sugars, accumulates in the skin.
Skin oil production starts to drop after age 25 and this drop in oil production becomes more serious after age 45. This reduces acne, however, the skin loses its natural moisturizers making the skin dryer and more prone to wrinkles.
- stimulating the skin's remodeling and regenerative processes which repair the skin's protective outer barrier
- increasing new capillary formation
- increasing the production of collagen and elastin which improve skin elasticity and firmness
- increasing the water-holding proteoglycans and glycosaminoglycans (GAGs) which hold moisture in the skin.
- removing damaged proteins such as in scars and sun-damaged marks by activating the metalloproteinases.
