The main ingredient of this and working serum: Argireline - a muscle relaxant. It does not influence the structure of the tissue and slows the conduction of nerve impulses and thereby gently relaxing muscle, reducing the depth of facial wrinkles and preventing the appearance of new ones. However, peptides muscle relaxants are effective only in the case of facial wrinkles and powerless against the wrinkles that arise due to structural changes in the skin. Therefore, with age-related skin changes and he can not cope. But in general, Argelin considered safe replacement to Botox! Serum except Argireline, also contains a hyaluronic acid for hydration. I put on a wet face. Ideally, once after the tonic. After soaking \ drying forms on the skin plenochku. I really like the effect of this serum. I use it with pleasure. Glass bottle with a convenient pump-dispenser. Consumption minimalnyy- enough 2-3 clicks. Economically. Comfortable to use. Shelf life is written directly on the bottle (I love when it's so convenient). ****** I hope my review was helpful to you !! * -))
