Natural Moisturising Factors

******FIRST DRAFT*****


Natural moisturizing factors (NMF) are substances that occurs naturally in your skin helps your skin to retain moisture. NMFs absorb moisture from the air surrounding you skin and lock it in the outer layers of the skin. The moisture then makes your skin proteins (the scaffolding) more agile that make your skin elastic and younger looking. The locked in water is also important for your skins natural exfoliation process (desquamation). Examples of NMFs are glycerin and hydraulic acid.

Glycerine (Glycerol) is a small hydrophilic (water-loving) molecule. In it s natural form it is a thick, transparent liquid, like a transparent syrup. It exists naturally and can be extracted from certain plants, e.g. soy beans. It can also be produced synthetically. It penetrates your skin easily and plays a crucial part in keeping your skin moisturized. (KOLLA LODEN artikel och lägg till lite)

Hyaluronic acid

HA occurs naturally in your body, it is used as a lubricant for the joints, space filling and plays a part in wound and injury healing. The main part of HA is found in your skin, where it works as a NMF. It has enormous water retention capabilities, up to 6 liters of water per 1 g HA.

When you are young you have a high content of HA in your skin, however the level decreases with age. The loss of HA is one of the reasons for loss of plumpness and drying of your skin. Further as you grow older the HA will bind to the structural proteins in your dermins which will make your “scaffolding” less agile, your skin will be less elastic and wrinkles will occur.

HA is a large molecule, a long chain of smaller building blocks (di-saccarider) and in its natural state it will not penetrate the skin. However during recent years researches have been able to reduce the size of the HA-chain without changing its properties. This nano-version has show to increase moisturazation and skin elasticity as well as reducing wrinkles (source: J Clin Aesthet Dermatol. 2014;7(3):27–29 ) more srouce Dermato-Endocrinology 4:3, 253–258; July–December 2012
