Allantoin

• Allantoin has been shown to increase cell turnover by increasing cell proliferation. This increased growth reduces dullness and improves healing.
• Has been demonstrated to reduce TEWL (transepidermal water loss) and can help to keep water in skin cells by acting like a sponge. The resulting effects help skin feel plump and soft.
• Allantoin has been shown to induce wound healing by regulating the inflammatory response of the skin
