Hyaluronic Acid (HA) is a clear, gel-like viscous substance. Hyaluronic Acid efficiently attracts and retains moisture(gram of HA binds 300-500 ml of water), it is also found naturally in the human body and has a significant effect on reproduction of cells and cell movement. About half of the hyaluronic acid is in the human skin, and one third is renewed daily.


  • Attracts and retains moisture;
  • Wrinkle prevention, reduces existing wrinkles;
  • Strengthens the skin's protective barrier;
  • HA in the skin accelerates wound healing and soothes inflammation;
  • Reduce acne;
  • Protects skin from free radicals;
  • Reduces facial redness.


In its original state, the molecule of Hyaluronic Acid is too large to penetrate through the stratum corneum (outer layer of the skin), so they are degraded to few types of molecules which are used in skin care products: low-weight (short-chain) and high-weight (long-chain) Hyaluronic Acids. Short-chain acid molecules are smaller, so they can penetrate into the deeper layers of the skin, while long-chain acid molecules are larger, so they moisturize the skin surface perfectly. Products enriched with two chain types of hyaluronic acids are very effective. HA is a substance also produced in human body, so HA derived from animal or plant origin (using bacteria) is well accepted and allergic reactions are particularly rare.

As the body ages natural levels of HA decrease, also some internal and external factors like solar radiation, air pollution, stress, the best diet or lifestyle can accelerate the process. To reduce aging and impact of negative factors Hyaluronic Acid is widely used in skin care products. It moisturizes the skin due to its irreplaceable capacity to hydrate (attract moisture to skin cells), ability to effectively reduce and prevent wrinkles and accelerate wound healing. Skin looks youthful, becomes more elastic, firmer and smoother.


HA in skin care is labeled under names: Sodium hyaluronate, Hyaluron, Glycosaminoglycan.

Dermatologists recommend using skin care products which contain no more than 1% HA and use doses of 120-240 mg per day. We all have different skin types, so it is necessary to consult a dermatologist or cosmetologist.

In “SIIN” Skin Care short-chain and long-chain Hyaluronic Acids are encapsulated in liposomes, so they can be absorbed into the deeper layers of the skin. HA can be found in all SIIN Skin Care creams, serums and sheet masks.
