Night time is when the skin is completely able to heal and regenerate itself. It is when new skin cells are created to replace the old, dead skin cells that your skin sheds when you exfoliate or use peeling products. This is why using moisturizer at night is important so you can help your skin along. Today, cosmetics and skin care companies are taking special attention to the night time regeneration of skin. This is why they have created specific night care products. These are usually moisturizers or creams meant to restore your skin’s hydration and keep it young and elastic.
