HySilk - low molecular weight

Hyaluronic acid is a transparent substance (hyalos means glass in Greek) with an exceptional ability to bind moisture. It works like a sponge, absorbing up to a thousand times its own weight in water. It is found in every tissue in the body and in areas that depend on moisture (the vitreous humour of the eye, connective tissue and the fluids surrounding our joints). It is also found in food, and you can stimulate its production through your diet. As we age, the concentration of water-binding hyaluronic acid in the skin decreases significantly. The skin's connective tissue therefore stores less water, leaving the skin looking less elastic and prone to wrinkles. Our hyaluronic acid is derived from microorganisms through biotechnological processes, ensuring high purity and environmentally friendly production without harmful effects on the environment or animals.

Its low molecular weight of 0.15 - 1.3 MDa allows it to penetrate deep into the skin, where it intensely hydrates the deeper layers, restores the lipid barrier and acts as a powerful antioxidant that blocks free radicals. It creates space within the tissues for the transport of substances needed for natural cell regeneration, enhancing the skin's ability to regenerate. The manufacturer's recommended concentration in creams is up to 1-2 %, maximising its hydrating and protective effects without overburdening the skin. Hyaluronic acid treatments are used to reduce the appearance of wrinkles, facial lines, sagging skin, scars and post-acne discolouration. It is used to treat burns and skin ulcers to restore hydration. It regenerates the skin, protects it against external factors, keeps it firm and supple, smooths existing wrinkles, prevents stretch marks, visibly improves problem skin, speeds up wound healing, prevents scarring and improves the supply of nutrients from the lower layers of the skin to the uppermost layers.

Ideal for dry, dehydrated, sensitive and mature skin, as well as oily and acne-prone skin, where it supports hydration without clogging pores. We recommend it to anyone dealing with wrinkles or loss of elasticity, or whose skin needs intensive regeneration after exposure to stress. In DULCIA natural creams, we use hyaluronic acid of the highest quality in the world, sourced from the world's leading manufacturer. The smaller the molecule, the deeper it penetrates into the skin and the greater its biological effects within the skin. By contrast, hyaluronic acid with a higher molecular weight does not penetrate as deeply, remaining in the upper layers of the skin, where it primarily acts as a moisturising agent and provides protection. We always add the maximum amount of hyaluronic acid recommended by the manufacturer to our creams.

A study published in the Journal of Clinical and Aesthetic Dermatology (2014) showed that topical application of a 0.1 % solution of low-molecular-weight hyaluronic acid (<500 kDa) increased skin hydration by 96 % and reduced transepidermal water loss by 30 % after 8 weeks of use. Further research in the International Journal of Biological Macromolecules (2017) showed that sodium hyaluronate with a molecular weight of 0.15-1 MDa improved skin elasticity by 20 % in women over 40 after 4 weeks. Dulcia natural uses high-quality hyaluronic acid with the most stringent Ecocert and COSMOS certifications, the world's most prestigious certifications for natural and organic cosmetics, guaranteeing a minimum of 95 % natural ingredients.
