What is Hyaluronic Acid ?

Hyaluronic acid (HA) is a molecule naturally present in the body, mainly in skin, joints and connective tissue. This key active ingredient is known for its exceptional capacity to retain water, up to 1000 times its own weight, making it a key ingredient in moisturizing and anti-aging skin care products. In cosmetics, it is used in various forms, such as high molecular weight (HPM) and low molecular weight (BPM) hyaluronic acids, which act at different levels of the skin. Its versatility and moisturizing efficacy make hyaluronic acid a must-have for keeping skin supple, plump and radiant.

Our hyaluronic acid salt acts as a humectant and moisturising active: by attracting water and retaining it, it helps to keep the skin moist and hydrated.

A natural component of connective tissue, it easily penetrates the epidermis and is capable of binding large quantities of water, up to 20 times its weight.
As hyaluronic acid is a fairly large molecule, it is its salt that is preferred in cosmetics: a much smaller molecule, which penetrates the deeper layers of the skin more easily.

Where does Hyaluronic Acid come from ?

The hyaluronic acid used in cosmetics is often obtained by biofermentation, a sustainable and eco-responsible process in which micro-organisms (such as lactic acid bacteria) produce this molecule. This method produces pure, effective and environmentally-friendly hyaluronic acid. Historically, hyaluronic acid was extracted from animal sources, but this practice is becoming increasingly rare. Today, its non-animal production makes it an ingredient compatible with vegan and natural formulations, reinforcing its popularity in modern skincare.

Properties and active ingredients :

  • Hyaluronic acid has a number of beneficial properties for skin and cosmetic care. Here are its main characteristics and actions:
  • Intense hydration: Thanks to its ability to retain water, it helps maintain optimal skin hydration, preventing cutaneous dryness.
  • Plumping effect: Improves skin density and elasticity, giving a plumper, smoother appearance.
  • Anti-aging: Visibly reduces fine lines and wrinkles by promoting water retention in the skin’s upper layers.
  • Healing and regeneration: Naturally present in tissues, it plays an essential role in skin repair and regeneration.
  • Universal compatibility: Non-irritating and hypoallergenic, it is suitable for all skin types, even the most sensitive.

What are the benefits of hyaluronic acid ?

Hyaluronic acid offers numerous benefits for the skin, thanks to its moisturizing, plumping and anti-aging properties. Here are the main benefits of this leading cosmetics ingredient:

  • Long-lasting hydration: It captures and retains moisture in the skin, keeping it soft, supple and luminous all day long.
  • Smoothes fine lines and wrinkles: By deeply rehydrating the skin, it helps fill in wrinkles and improve the appearance of fine lines, especially on the forehead and around the eyes.
  • Improved skin elasticity: firms skin by supporting collagen and elastin production, for a visibly more toned face.
  • Reduces redness and irritation: Thanks to its soothing and repairing effect, it calms irritated or sensitive skin, helping to restore the cutaneous barrier.

Suitable for all skin types: From dry to oily, it regulates hydration without weighing down or causing shine.

ITS BENEFITS:

  • Moisturises the skin
  • Promotes healing and cell regeneration
  • Soothes irritation and discomfort

How is Hyaluronic Acid used ?

Hyaluronic acid is mainly used topically in skincare products for its moisturizing and plumping properties. Here are the main ways to benefit from this ingredient:

  • Moisturizing serums: In cosmetics, serums enriched with hyaluronic acid of different molecular weights act both on the surface and deep down for complete hydration.
  • Anti-aging creams: Incorporated into creams, hyaluronic acid plumps skin and reduces the visible signs of aging, such as fine lines and wrinkles.
  • Face masks: In mask form, it offers an intense moisturizing effect, ideal for dehydrated or stressed skin.
  • Eye contour products: Applied around the eyes, it helps reduce dark circles, puffiness and fine lines.
  • Dietary supplements: Available in capsule or powder form, hyaluronic acid can be consumed for hydration and skin regeneration from within.

Note: To maximize hyaluronic acid’s effectiveness, apply it to slightly damp skin, followed by a cream to seal in moisture. It can be used morning and night, alone or in conjunction with other skin care products.

Any side effects ?

Hyaluronic acid is generally well tolerated, but some rare side effects may occur:

  • Sensation of tightness: Used alone without moisturizer, it can sometimes accentuate the sensation of dryness. Always combine with an emollient.
  • Allergic reactions: Although rare, hypersensitivity to hyaluronic acid can cause redness or irritation.
  • Environmental sensitivity: In very dry climates, it can draw moisture from the skin instead of ambient air, leading to dehydration. Additional hydration is then recommended.
  • Potential interference with certain treatments : If you use specific dermatological treatments, such as retinol or exfoliating acids, hyaluronic acid may be less effective or accentuate skin sensitivity.

Intolerance to injectables: In the case of aesthetic injections, slight reactions such as redness or swelling may occur temporarily.
