Glycolic acid and hyaluronic acid: can we mix these two key active ingredients in cosmetics?
At the heart of the best cosmetic formulations for years, hyaluronic acid is an essential moisturizing active ingredient that needs no introduction. But today, a new star ingredient is making its way into skin care: glycolic acid . This fruit acid is renowned for its anti-aging properties and its powerful exfoliating effect. So, can glycolic acid and hyaluronic acid be mixed for an effect that is both moisturizing and regenerating? What are the benefits of this combination of active ingredients for the skin? Find all our advice for combining them effectively in your beauty routine.
Glycolic acid and hyaluronic acid: the benefits for the skin
These two active ingredients are integrated into facial care for their unique properties.
Glycolic acid: cell renewal and smoothes skin texture
Derived from sugar cane, glycolic acid is one of the AHAs (alpha-hydroxy acids). It is a naturally occurring exfoliant highly valued in dermatology for its multiple benefits:
- Smoothes skin texture
- Improves the appearance of dark spots and wrinkles
- Removes dead cells
- Provides a peeling effect that promotes cell renewal.
Hyaluronic acid: hydration and firmness of the skin
For its part, hyaluronic acid is a molecule naturally present in the dermis , which makes it more elastic and contributes to its hydration . But its production decreases with age and external aggressions, and the skin thus loses firmness .
There are several forms of hyaluronic acid , each providing specific benefits:
- High molecular weight hyaluronic acid acts as a protective barrier on the skin's surface.
- Low molecular weight hyaluronic acid penetrates into skin tissues for deep , long-lasting moisturizing action .
- Cross-linked hyaluronic acid is chemically modified to retain water and slow down skin aging .
Why combine glycolic acid and hyaluronic acid? The advantages
By combining these two active ingredients, you get a revitalizing duo for the skin.
Improved hydration and radiance
The acids work in synergy to limit dryness and help maintain hydrated , radiant skin .
Reduction of wrinkles and fine lines
The moisturizing power of hyaluronic acid, combined with the keratolytic action of AHAs, fills in wrinkles, reduces the appearance of signs of aging and pigment spots.
Improved skin texture
The exfoliating effect provided by glycolic acid allows hyaluronic acid to better penetrate the epidermis, to erase irregularities, dead cells as well as to protect and plump the skin .
Can you mix glycolic acid and hyaluronic acid? Precautions and risks
The combination of these two active ingredients in cosmetic treatments must respect certain rules to avoid undesirable reactions.
Potential side effects to be aware of
Mixing acids for cosmetic care can cause various reactions, such as:
- Tingling

Application tips for optimal use
Most side effects are due to improper use of glycolic and hyaluronic acids. Here are some precautions to avoid these unpleasant effects.
Start with a low concentration
This is the best way to avoid irritation: introduce a small amount of product and observe the skin's reaction. Glycolic acid is particularly linked to redness and itching on sensitive skin.
Optimal application of glycolic acid and hyaluronic acid: in what order?
You can apply glycolic acid and hyaluronic acid at the same time, without overloading the face. Opt for a complete treatment that includes these active ingredients for an anti-aging action while providing the necessary hydration to your skin.
Ideally, always apply your serum or hyaluronic acid treatment before your day cream or night cream. Moisturizing prepares the skin to receive the appropriate care and protects it from external aggressions.

Compatibility with other skin care actives
Can glyconic acid and hyaluronic acid be mixed with other active ingredients? Although both ingredients are beneficial for the skin, they can be combined with certain active ingredients to treat specific skin concerns.
Glycolic Acid vs Salicylic Acid: Can You Mix Them?
Salicylic acid (BHA) is particularly suitable for combination to oily skin. It is a powerful active ingredient for improving the overall appearance of the skin . Like glycolic acid, it has exfoliating properties that make it very effective on blemished skin and enlarged pores.
But combining two exfoliating agents can irritate the skin: it is better to alternate their use or to opt for cosmetic products that also contain very moisturizing ingredients such as hyaluronic acid, especially on sensitive skin.
Hyaluronic Acid vs Niacinamide: Which One to Choose?
Niacinamide, or vitamin B3, is an anti-aging active ingredient with multiple benefits , which stimulates the production of collagen and helps fight against sagging skin.
Combined with the incredible water retention capacity of hyaluronic acid, this active ingredient can work miracles on mature skin .
It is therefore advisable to use them in synergy to increase the moisturizing effect, strengthen the skin's barrier effect and act significantly against the signs of aging .
Retinol and AHA/BHA acids: understanding their respective benefits
Retinol alone offers stunning before and after results in anti-aging skincare. Contrary to popular belief, AHA/BHA exfoliating acids do not reduce the effectiveness of retinol . However, it should be integrated gradually if the skin is not used to it, only in the evening routine.
AHA/BHA provide an exfoliating effect that complements the antioxidant and rejuvenating action of retinol.
