Skin regenerates daily, but factors such as aging, pollution, and excessive sunlight can slow down the process. Antioxidants and chemical peels can promote skin regeneration and produce younger-looking skin, but severe injuries may require skin grafts.
Skin regeneration is the renewal of the skin surface. Every day, the body produces new skin cells. They start in the deep layer of the dermis and eventually move into the epidermis, which is the surface of the skin. Over time, they shed and fall off. Skin cells can regenerate and move to the surface layer within two weeks, but this is typically only true for younger skin.
The skin never stops regenerating, but some factors can slow down this process. As a person ages, collagen production in the skin slows down. Collagen is responsible for keeping skin firm. Without it, cell production slows down and skin can become saggy and more susceptible to wrinkles. Pollutants in the air can also slow down the skin’s regeneration process.
Sunlight is healthy for your skin because it supplies vitamin D, but too much sunlight can damage your skin irreversibly. This also slows down the production of collagen and causes the skin to dry out. Moisture is needed for better skin regeneration, especially when it has been exposed to excessive sunlight. Keeping your skin hydrated can reduce wrinkles and speed up the regeneration process.
There are cases when the skin simply does not regenerate. If the dermis or epidermis is severely injured, it will not grow back. Skin grafts can be used to cover a lesion when it is too large to be closed. An injury such as a deep, large cut that penetrates the dermis or a burn that destroys the top layer or epidermis can also produce scarred or uneven layers of skin.
You can take steps to promote skin regeneration. Some vitamins and foods contain antioxidants that fight against skin aging. Antioxidants can also help eliminate free radicals that cause some types of cancer. Not only can these antioxidants help speed up the skin’s regeneration process, but they can also produce younger, healthier looking skin.
Chemical peels can also be used to rejuvenate the skin. This treatment involves applying small amounts of acid to the skin to remove the upper epidermal layers. There are different types of chemical peels used, depending on how damaged the skin is. Some chemical peels only remove a small amount of skin, while others penetrate the skin and remove more.
