The skin of the lips is thinner than other body sites and naturally loses contour with age, which is aggravated by constant movement. This contributes to a greater appearance of wrinkles and expression lines in the lip area.

Furthermore, as Natura inventors explain, since the epidermis in this area region is less thick, the lips are more intensely exposed to environmental aggressions, i.e., sun, wind and cold, and are therefore more susceptible to dryness, presenting with cracks and intense flakiness.

The Problem
Combining these and other factors such as loss of collagen with age and the lip region develops deeper wrinkles (from 250-400 micrometers). Cosmetic compositions effective in reducing the amount of wrinkles in this region are therefore desired; this was the focus of the present patent application.
