Urea is a natural component of our skin’s tissues. It makes up to 10% of natural moisturizing factor, which decreases with age. Applied on the skin, it penetrates the stratum corneum, where it readily absorbs and re- tains water, thus increasing the capacity of the skin to hold moisture and rehydrate. At a molecular level, urea modifies the structure of aminoacids and polypeptides chains within the skin, which is important for helping to moisturize our delicate tissues. Urea’s numerous benefits is that it helps to accelerate the skins cellular renewal process. Urea works in syner- gy with ingredients that create the molecular structure of the skin.It actively works to remove dead skin cells and substances from the horny layer, improving cellular turnover in the epidermis and preventing water loss through the skin.
