Effect: Hyaluronic acid forms an uninterrupted thin film on the surface of the skin, which then maintains the natural moisture levels without disrupting the gaseous exchange with the environment. It does not cause allergic reactions or irritations. It prolongs the action of biologically active cosmetics ingredients, which raises their efficiency significantly.

Ingredients: Hyaluronic acid, Chitosan.

Instructions for use: cosmetologists may use L.R.N. Hyaluronic acid as an addition to creams and masks, combining it with machine cosmetology treatments, such as Ultrasound and Galvanic devices. For home use apply after the moisturising cream onto the face and neck.
