Hyaluronic Acid Aroma-Zone Profile

INCI Name: Sodium hyaluronate

VEGAN - LABELS

BIOCHEMICAL COMPOSITION

Hyaluronic acid consists of polysaccharides (sugar chains) from the glycosaminoglycan (or GAG) family. It is a long molecule in which the disaccharide unit formed by D-glucuronic acid and D-N-acetylglucosamine repeats. Depending on the number of repeating "disaccharide" units, the molecular weight of hyaluronic acid varies between 5 and 10,000 kDa.

TRACEABILITY & SUSTAINABILITY

Naturally derived active ingredient - The vegan hyaluronic acid we use at Aroma-Zone is produced using biotechnology (fermentation of glucose and plant-based peptones).

Hyaluronic Acid: What Effect Does It Have on the Skin?

Hyaluronic acid is a natural component of connective tissues: skin, cartilage, synovial fluid, cornea and more. It is a glycosaminoglycan, that is, a carbohydrate macromolecule, and constitutes one of the most important elements of the skin's extracellular matrix. This matrix also includes proteins such as collagen and elastin. Hyaluronic acid binds with these proteins to form a network thanks to its ability to attract and retain large amounts of water (up to 1,000 times its weight in water), forming an elastic gel. This network provides the skin's supportive structure.

It is this ability, among others, that gives young skin its volume and elasticity. Hyaluronic acid is constantly renewed by the skin: its natural lifespan is very short, with around a third of its molecules replaced by the body every day. With age, the body synthesises less hyaluronic acid. The amount of hyaluronic acid gradually decreases, and the skin loses its plump appearance.

As a cosmetic active ingredient, its exceptional water-retention capacity is recognised for hydrating and plumping the skin, even at low concentrations. Its moisturising properties also help promote skin regeneration by stimulating the proliferation of epidermal and dermal cells, including keratinocytes and fibroblasts. Because it occurs naturally in the skin, it's also very well tolerated, even by sensitive skin.

Hyaluronic Acid: Scientifically Proven Efficiency

A study examined the efficacy of a cream containing 0.1% hyaluronic acid of various molecular weights as an anti-ageing treatment on 76 women. After 2 months, their skin’s hydration and elasticity were significantly increased compared to the placebo. The appearance of wrinkles was also improved in the group that applied low-molecular-weight hyaluronic acid.

Skin Tolerance

A Note from Adeline Nalin, Head Pharmacist and Toxicologist at Aroma-Zone

Adeline Nalin blouse

“Hyaluronic acid is very well tolerated by the skin, even sensitive skin, thanks to its structure, which is naturally present in the dermis (biomimicry). Its excellent tolerance is confirmed even at concentrations of up to 3.5%. Hyaluronic acids are characterised by their molecular weights, which directly influence skin penetration and thus local tolerance.”

A Safe Ingredient for your Health

A Note from Our Aroma-Zone Toxicologist

“Hyaluronic acid is a universal molecule whose structure is identical in all living beings, whether bacteria, animals or humans. Naturally present in our bodies, it is recognised as an endogenous substance that is well-tolerated by the skin. At the concentrations used in cosmetics, it is non-toxic, non-sensitising and perfectly safe. Its action consists of supporting existing physiological functions without altering the skin's balance.”

A Note from the Dermatologist

“Naturally present in the skin barrier, hyaluronic acid acts like a sponge, retaining up to 1,000 times its weight in water, which helps hydrate and soften the skin. It is suitable for all skin types, and I recommend it especially for skin lacking hydration. Lightweight and non-comedogenic, it easily fits into any skincare routine without weighing down the skin and can be applied both morning and night. A little tip: feel free to apply it to slightly damp skin and seal in the moisture with a moisturiser.”

Formulation Focus with the Aroma-Zone R&D Laboratory

Hyaluronic acid exists in a wide variety of molecular weights, an essential characteristic in formulation as it determines its distribution within the skin. The larger forms remain on the surface to provide immediate hydration, while the smaller ones diffuse more easily into the upper layers of the epidermis. Combining multiple sizes thus allows for comprehensive hydration.

For Which Skin Types?

All skin types, dehydrated skin, first signs of ageing, mature skin.

Which Concerns Does This Address?

Dehydration, loss of firmness and elasticity, wrinkles and fine lines.

What Hyaluronic Acid Does for the Skin

  • Intense, long-lasting hydration

  • Firms the facial contours

  • Improves skin elasticity

  • Reduces the depth and width of wrinkles

  • Plumps and softens the skin.
