Bienfaits de l'acide hyaluronique pour la peau.

The benefits of hyaluronic acid.

The hyaluronic acid is a complex sugar highly hydrophilic, naturally present in the human body in the joints, muscles, eyes and especially the skin. The amount of hyaluronic acid present in the dermis tends to decrease with age, leading to skin sagging and the appearance of wrinkles. This molecule, when applied topically, brings numerous benefits to the skin.

Our range of hyaluronic acid skincare products.

What is hyaluronic acid?

Hyaluronic acid is an active ingredient that constitutes the extracellular matrix of the body. Nearly 50% of its total quantity is located in the dermis, the deep layer of the skin. The other half is distributed in the eye and the synovial fluid of the joints. This biomolecule was discovered in 1934 in the vitreous humour of a bovine eye by Karl MEYER and John PALMERER. In the animal kingdom, hyaluronic acid is primarily concentrated in the comb of the rooster and the cartilage of the bovine's snout.

The function of hyaluronic acid is to ensure the hydration of the skin. At the dermis level, it contributes to the formation of its connective tissue and serves as a support for collagen and elastin fibres. Thus, it plays a fundamental role in the density and firmness of the skin.

Hyaluronic acid is currently frequently used in aesthetic medicine in the form of injections. This active ingredient is also included in the composition of numerous cosmetic treatments, which are equally effective and have the advantage of being less invasive than an injection.

The benefits of hyaluronic acid for the skin.

Hyaluronic acid is a component of many skin care products (serums, creams, lotions, balms...). Its benefits are numerous and varied:

Hyaluronic acid hydrates the skin.

This active ingredient acts like a molecular sponge: it is capable of binding up to 1,000 times its weight in water. It is thus particularly favoured for taking care of dehydrated skin, as well as mature skin showing signs of skin sagging, wrinkles and fine lines.Hyaluronic acid fills the intercellular spaces by combining with water, which hydrates, softens and tones the skin. The skin regains its elasticity and firmness.

  • Hyaluronic acid forms a protective barrier against external aggressions.

    This ingredient contributes to theestablishment of a skin barrier that protects the layers of the skin from the harmful effects of UV rays and free radicals.

  • Hyaluronic acid contributes to the healing of the skin.

    It soothes any irritations and redness that may occur, and contributes to the rebuilding of damaged skin tissues.

Typology has developed several products containing this potent hydrating agent capable of retaining up to 1,000 times its weight in water:

  • The moisturising cleansing milk, composed of 0.5% hyaluronic acid, gently removes all impurities that may have accumulated on the surface of the epidermis, without damaging the skin or weakening the hydrolipidic film. The composition also includes coconut oil and chamomile hydrosol, which nourish and limit discomfort reactions, respectively. It is primarily aimed at individuals with dry to normal skin ;

  • Combined with aloe vera to deeply and sustainably hydrate the skin, the tonic moisturising lotion helps to regulate the skin's pH after the makeup removal/cleansing stages, and to eliminate the limestone residues present in the water and deposited on the face, which can potentially cause irritation. It helps to rehydrate the skin and reduce the sensations of tightness characteristic of dry skin ;

  • The hydrating serum is composed of 94% natural origin ingredients and makes the skin more plump after only a few weeks of use. It contains 3% hyaluronic acid and 2% of provitamin B5 which stimulate the regeneration of dermal and epidermal cells, thus reducing insensible water loss;

  • Hyaluronic acid is combined with coconut oil in the face moisturising cream containing 9 ingredients. This minimalist formula hydrates and nourishes the epidermis. Its light and non-greasy texture is suitable for dry, normal and combination skin, even sensitive ones;

  • The nourishing face cream is enriched with lipid-replenishing and moisturising actives, and composed of 98% natural origin ingredients. It restores suppleness to the skin and reduces feelings of tightness;

  • The face sun creams SPF30 and SPF50 prevent photoaging through the combination of mineral and organic filters offering broad-spectrum UVA/UVB protection. This protective care is enriched with aloe vera, karanja oil and hyaluronic acid derived from fermented wheat. The clever blend of these three components prevents photoaging, while maintaining skin hydration.

  • The hand & nail serum combines hyaluronic acid with plant keratin. It helps to strengthen the nails and smooth out roughness. To repair your nails, apply a few drops of this serum or incorporate it into your usual hand cream ;

  • The hand balm with 10 ingredients is suitable for all skin types, including sensitive skin. This minimalist formula care is enriched with hyaluronic acid to combat dryness and potential irritations.
