Moisturizers rehydrate the top layer of skin cells and seal in water. It is one of the best ways to treat dry skin.
Apply moisturizer to your face after cleansing and before bed. This will increase the hydration level of the corneum (outermost layer of the epidermis), and stop the skin from drying out. Some moisturizers also contains a sunscreen to protect against sun damage.
The moisturizer also alters the skin’s natural balance of proteins, water, and lipids. This helps the skin hold and retain water and and keeps the skin well hydrated. Moisturizer is necessary for all type of skin including oily and dry skin.
