It involves filling with known agents commonly used for skin lifting.

The first agent involves a protein present in the connective tissue of the human and animal body. Among other things, it is found in our skin, bones, tendons, teeth and in our cartilage. In the skin, collagen provides strength and elasticity. Consequently, a decrease in this protein in the skin causes a decrease in elasticity and firmness. This happens anyway as the skin ages. Normally, protein production declines steadily from the age of 25 and the skin gradually becomes less young, firm and supple. The skin weakens, wrinkles appear and the skin starts to suffer more from external conditions such as the weather.There are more than 20 different types of protein, human, animal and plant. For example, there is fish protein, bovine protein, pig protein and plant protein. Several types of protein are used in cosmetics, especially fish protein and bovine protein. They are often incorporated into creams to give extra protection to the skin. In plastic surgery, this protein is often used to fill the skin where it has collapsed.

The second agent is a preparation based on a natural substance found in connective tissue, epithelial tissue and nerve tissue, among others. These preparations are used in the cosmetic world for facial fold correction, lip augmentation and G-spot augmentation, among others. In this case, the substance is usually incorporated into a gel that will be slowly broken down by the body. A number of anti-wrinkle creams also contain this substance.
