As of age 25, our skin begins to show signs of aging. Cellular renewal slows down and cells synthesize less protein, leading to a weakening of the skin, which reveals signs of aging more easily.

Skin aging on the face is characterized by three main occurrences:

•the appearance of wrinkles and fine lines

•the tendency of volume to diminish and creases to deepen

•the slackening of the facial skin due to a loss of elasticity and skin dryness

Along with wrinkles, dark spots are one of the first signs of skin aging. Darker than freckles, these flat spots, also called lentigo, can reach one centimeter in diameter. They appear on the hands, face and décolleté. Two main causes of the formation of lentigo are excessive sun exposure and skin aging.

Aggravating factors: External factors such as UV rays, pollution and smoking aggravate the aging process. They can accelerate and reinforce aging. The quantity of UV rays that we are exposed to during our life is a determining factor, to the extent that we talk of “photo-aging”. All of these factors generate free radicals that modify the genetic heritage of the cells and break down their DNA. As a result, year after year, the quality of our cells is damaged.
