Potassium Myristoyl Hydrolyzed Collagen

Potassium myristoyl hydrolysed collagen is a modified form of collagen that has been broken down (hydrolysed) and combined with myristic acid, a fatty acid. This processing makes the collagen molecule smaller and more able to interact with the skin's surface, where it functions as a conditioning agent rather than being absorbed into deeper layers.It is used primarily in skincare and haircare products for its film-forming and moisturising properties. The ingredient works by coating the skin or hair to help retain moisture and improve texture and appearance.

Helps with Anti-Ageing

The hydrolysed collagen molecules are small enough to sit on the skin's surface, where they form a film. The addition of myristic acid (a fatty acid) enhances the ingredient's ability to interact with skin lipids and improve moisture retention. This film-forming action helps to reduce transepidermal water loss (TEWL)—the evaporation of water from the skin—thereby keeping skin feeling hydrated and conditioned.Because the collagen is hydrolysed, it does not penetrate deeply into the epidermis, but rather works as a surface-active moisturiser and skin-conditioning agent.

This ingredient is most effective when used in leave-on products such as serums, moisturisers, or creams, where it can remain on the skin to form its conditioning film. It works well in layered routines and can be combined with other hydrating or conditioning ingredients. There is no upper limit on how often it can be used, though like all conditioning ingredients, it works best as part of a consistent skincare routine rather than as an occasional treatment.

Potassium myristoyl hydrolysed collagen is generally well-tolerated and considered safe for cosmetic use. It is unlikely to cause irritation for most skin types, though those with specific sensitivities to collagen-derived ingredients should patch test first.
