A product containing 2% hyaluronic acid is the maximum that the skin can absorb without problems. Hyaluronic acid, like any other in 100% concentration, causes an instant chemical burn! In the composition of 50% high molecular weight, 50% low molecular weight acid. Small molecules pass through the cellular barrier and work from the inside out, replenishing water balance and rebuilding collagen fibers. Large molecules remain on the surface and act as a protective barrier against external factors and prevent the acquired moisture from evaporating. The basis of product No. 1 is the microbiological synthesis of highly purified hyaluronic acid. For this process, we have developed technical regulations and formed a full-fledged section of microbiological synthesis. To maintain the highest and stable quality of the final synthesis product, we use components of the best world companies from Sweden, USA, Germany and Japan in the production, because they are the best. Based on the highest quality hyaluronic acid obtained in our laboratory, we produce a serum (acid-based product) with hyaluronic acid, which, due to a stable minimalistic composition, allows you to get the maximum effect from the final product. And the minimum amount of preservatives allows you to preserve and convey to you a fragile but effective molecule of hyaluronic acid, which, being a large polysaccharide, is easily destroyed by aggressive external factors, incl. from excessive aggressive preservatives. The product is organic, the simplest and most natural composition. Beauty and benefits for your skin! Disinfected glass containers for protection. Differs from most products in a thick consistency.
