1. The cuticle of scar skin is thicker than that of normal skin, so it is difficult for general scar-removing components to reach the inside of scar through the thick cuticle.

2. Scar skin tissue structure is destroyed, and a large number of fibroblasts proliferate to replace normal skin tissue, which is difficult to remove.

3. The abnormal distribution of pigment in the scar leads to serious dormitory loss and accumulation, which leads to the scar color being different from normal skin.

The unique carnosine growth factor contained in South Korea's Lee Kee can decompose the pigmentation caused by scar layer by layer, truly repair the damaged pigment mother cells at the muscle base, restore the normal secretion of pigment, and restore the normal skin color of the scar, thus removing the 20-year-old scar.
