The skin’s outer layer is a key factor in keeping the skin hydrated through moisture retention and sebum (skin oil) production. This layer is held together by lipids or fats and this layer can be broken down by many environmental conditions such as cold or dry weather. These conditions along with other harsh ingredients like detergents and chemicals break down these fats.
Moisture can then evaporate resulting in dry skin and if those pollutants get lodged in the skin, irritation and excess oil production can occur as well as a number of skin conditions. Hydrating skin care products can assist in maintaining the balance of the skin’s outer barrier and you can gain even more benefit by incorporating essential fatty acids and hdl cholesterol (like those in fish) into your diet.
