Genetic factors. In adolescence, the estrogen level is high, the face contour is well define, and the skin is smooth and elastic. However, hormone levels and the number of cells that give volume to the skin decrease over the years, The arrival of menopause accelerates this.
Environmental factors. Continued exposure to sunlight causes the progressive degradation of hyaluronic acid and collagen in the skin.
The lifestyle: Carrying a healthy lifestyle and eating habits affects the state of the skin. In addition, the ingesting of nicotine and other tobacco chemicals reductions the properties of it.

Eye Contour Gel
These gels typically contain retinol, collagen, and it and offer intense hydration and wrinkle reduction.
Night Cream
They are base on collagen and are use to treat the signs of ageing.
