These ampoules contain 100% pure evening primrose oil with a naturally high content of gamma-linoleic acids. These ampoules are especially recommended for the treatment of dry, rough and flaky skin. For damaged, chapped skin, evening primrose oil is a product which does not burn and which is often used on its own. In these circumstances it is advisable to treat the skin first only with EVENING PRIMROSE OIL ampoule and eventually in combination with the CERAMIDE ampoule, and then to progress to a complete skincare regime with liposomes and moisturizer. Evening primrose oil can also be taken orally to provide the body with gamma-linoic acids. A drop 2 to 3 times per day is adequate.
