Active ingredient: hyaluronic acid

Hyaluronic acid is naturally present in many tissues and fluids of our body. It allows, for example, the sliding of bone surfaces between them. However, the skin is the element of the human body that contains the most hyaluronic acid. With collagen, it is indeed what allows the dermis to keep its structure, to remain firm and well hydrated.

Many C27 cosmeceuticals are composed of hyaluronic acid. However, this molecule has different functions in each of our products.

What is hyaluronic acid?

A natural component of the skin, hyaluronic acid was discovered in the early 1930s by the biochemist Karl Meyer. Hyaluronic acid was first used in ophthalmic surgery and then, since the 1990s, in aesthetic medicine.

Hyaluronic acid is found in the intercellular space of the epidermis and is used to reconstitute the structures of the skin and regulate hydration. As we age, the body produces less hyaluronic acid. Thus, it is considered that the skin contains only half of its initial hyaluronic acid at the age of 50. Without enough hyaluronic acid, the skin is less supple and firm, the features start to deepen and the first wrinkles form.

Industrially produced hyaluronic acid takes many forms: injections, dietary supplements and of course creams.

At Cosmetics 27, the molecule is present in our care products in the form of Sodium Hyaluronate, Disodium Acetyl Glucosamine Phosphate and hydrolyzed hyaluronic acid.

What are its properties on the skin?

 Hyaluronic acid has three functions for the skin: it participates in the synthesis of collagen, it maintains hydration and protects the dermis from external aggressions.

To maintain a beautiful and supple skin, it is important to provide the skin with a sufficient quantity of hyaluronic acid.

The action of hyaluronic acid varies according to its molecular weight and the way the molecule is split. In cosmetics, hyaluronic acid can therefore be used as a maintenance agent, as well as a humectant, conditioner and moisturizer.

The molecule, known to significantly improve skin hydration, forms a dense viscoelastic network with water that helps the dermis maintain its density and elasticity. Hyaluronic acid also stimulates skin regeneration and tones the skin tissue.

At Cosmétics 27, hyaluronic acid is integrated in our anti-aging ranges, but also in our sensitive skin serums and our moisturizers. You will also find this molecule in the following products: Essence 27, Recovery 27, Booster 27, Mask 27 and Eyes 27.

Essence 27 and Mask 27 will work specifically on moisturizing the skin, while Recovery 27 Sensitive Skin Serum will soothe the skin while helping to replenish it. Focused on the regeneration process of the dermis, the Booster 27 anti-aging serum will accompany you to protect the skin of the face against external aggressions. Hyaluronic acid can also act on the sensitive eye contour area: Eyes 27 will help you to effectively treat puffiness and dark circles.
