Take the skin test and I'll show you how suitable this product is for you.
Take the skin testThe 1st self-rehydrating replumping ecobiological serum. It rehydrates and replumps immediately and lastingly, reduces visible signs of aging, and strengthens the skin barrier.
Hydrabio Hyalu+ serum is a watery-light serum from Bioderma, a brand based in France. The formula is built mainly around hydration. The ingredient list runs to 24 ingredients, each broken down in full below.
By its ingredient list the formula reads as very light — essentially a water-and-humectant base with little emollient weight. With almost no emollient load it should absorb quickly and finish close to matte. Hydration is handled by Butylene Glycol, Glycerin and Propanediol, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Propanediol and Hydrolyzed Hyaluronic Acid.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Niacinamide, Adenosine, Sodium Hyaluronate and Tocopherol.
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, cell renewal and firmness signalling. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it.
Reading the full list, the formula is essential-oil-free, no drying alcohol, paraben-free, silicone-free, microplastic-free and sulfate-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance, worth knowing if your skin reacts to any of them.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Calms redness, irritation, and inflammation for sensitive skin
