Quel(s) actif(s) ne pas mélanger avec l'acide hyaluronique ?

Which active ingredient should not be mixed with hyaluronic acid?

Some reminders about hyaluronic acid.

Hyaluronic acid is present naturally in the dermis, the deep layer of the skin. The body produces hyaluronic acid as part of its natural hydration mechanism. Hyaluronic acid molecules are also used to lubricate joints and keep the skin hydrated. They play an integral role in maintaining the skin's youthful and plump appearance, just like collagen.

Hyaluronic acid is what we refer to as a humectant, that is, a type of molecule that acts as a magnet to attract water molecules.

However, as we age, our reserves of hyaluronic acid deplete and this molecule is produced less and less by certain biological constituents. This depletion process can be accelerated by lifestyle factors, such as smoking or alcohol consumption, and by living in a polluted area. This is where topical hyaluronic acid-based skincare products come into play. These products help to restore skin hydration and even promote its elasticity.

Are there any contraindicated associations with hyaluronic acid?

Hyaluronic acid, being a natural component of the skin produced by the body, is a particularly gentle and well-tolerated active ingredient in topical application.

It's important to know that certain cosmetic actives do not interact well when layered on the skin. This can minimize their respective impacts and/or cause varying degrees of skin irritation. However, hyaluronic acid is a gentle ingredient that pairs well with all cosmetic actives! Moreover, being primarily a hydrating and soothing agent, it is ideal to mix it with other more aggressive ingredients to mitigate potential irritations and/or skin dryness. For example, the following combinations are recommended:

  • Hyaluronic Acid + Benzoyl Peroxide (BPO)

    Benzoyl Peroxide (BPO) is an active ingredient recommended for the treatment of acne. It acts on the bacteria responsible for the formation of pimples and reduces inflammation. However, it can dry out the skin and cause tightness. To avoid these discomforts, applying a hyaluronic acid treatment during the BPO regimen is recommended to maintain proper skin hydration.

  • Hyaluronic Acid + Fruit Acids (AHA)

    Alpha-hydroxy acids (AHA), such as glycolic acid or lactic acid,gently exfoliate the skin to unclog pores, remove dead cells, and restore radiance. However, they can slightly dehydrate the epidermis. Therefore, it is recommended to use ahyaluronic acid-based treatmentto keep the skin well-hydrated.

  • Hyaluronic Acid + Retinol

    Retinol belongs to the family ofretinoids, which are derivatives of thevitamin A,such as retinoic acid and retinal. It is considered one of the most effective compounds forcompensating for the degradation of the skin's support fibersandstimulating cell renewal. It boosts the production of collagen and elastin. When applied topically, it is metabolized into itsacid form, which is particularly active in combating skin aging and loss of firmness.

    However, this compound can be drying, especially for the most sensitive skin types. Therefore, pairing it with a moisturizing agent like hyaluronic acid during your beauty routine can be beneficial. We advise applying the hyaluronic acid treatment before the retinol one, preferably in the evening as retinol is a photosensitizing substance (it increases the skin's sensitivity to the sun's UV rays).
