As a person ages, the production collagen in the skin slows down. Collagen is responsible for keeping the skin firm. Without it, cell production slows down and the skin can become saggy and more susceptible to wrinkling. Pollutants in the air can also slow done the skin regeneration process. Sunlight is healthy for the skin because it provides vitamin D, but too much sunlight can damage the skin irreversibly. This also slows down collagen production and causes the skin to become dry. Moisture is needed for improved skin regeneration, especially when it has been exposed to excessive sunlight. Keeping the skin hydrated can reduce wrinkling and speed up the regeneration process. Steps can be taken to help with skin regeneration.
Certain vitamins and foods contain antioxidants that fight against the aging of skin. Antioxidants can also help to eliminate free radicals that cause certain types of cancers. These antioxidants can not only help to speed up the skin regeneration process, but they can also produce younger and healthier looking skin.
