What is skin regeneration?

Skin regeneration is the renewal of the skin's surface. Every day, the body produces new skin cells. They start in the deep layer of the dermis and eventually move down to the epidermis, which is the surface of the skin. Over time, they loosen and fall off. Skin cells can regenerate and move to the top layer within two weeks, but this is usually only true for younger skin.

The skin never stops regenerating, but some factors can delay this process. As a person ages, the production of collagen in the skin decreases. Collagen is responsible for keeping the skin firm. Without it, cell production slows 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 provides vitamin D, but too much sunlight can irreversibly damage your skin. This also slows down collagen production and makes the skin dry. Moisture is needed to enhance skin regeneration, especially when it has been exposed to excessive sunlight. Keeping the skin hydrated can reduce wrinkles and speed up the regeneration process.

There are cases when the skin simply will not regenerate. If the dermis or epidermis is severely injured, it will not grow back. Skin grafts can be used to cover an injury when it is too large to be sutured. An injury such as a deep, wide cut that penetrates the dermis, or a burn that destroys the top layer or epidermis can also result in scarred or uneven layers of skin.

Steps can be taken to help with skin regeneration. Certain vitamins and foods contain antioxidants that fight against skin aging. Antioxidants can also help eliminate free radicals that cause certain types of cancer. These antioxidants can not only help speed up the skin's regeneration process, but can also lead to younger, healthier looking skin.

Chemical peels can also be used to rejuvenate the skin. This treatment involves putting small amounts of acid on the skin to remove the upper epidermal layers. Different types of chemical peels are 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.
