Maintenance of skin hydration is critical to having a healthy functioning and healthy looking skin. Poor skin hydration can lead to other skin disorders and premature aging. A balanced approach using humectant and emollient moisturisers provides the best way to avoid dry skin problems.

The Natural Moisturising Factor (NMF)​ is a complex mixture of water-soluble compounds that serve to “bind” water in the skin. Component ingredients such as glycerin and hyaluronic acid are humectants that attract and hold water to reduce water loss through the skin surface. It is important for skin health to maintain a correct balance of skin humectants such that NMF functions to retain water and adequately hydrate the skin.
