Take the skin testThe rehydrating serum for thirsty skin. Formulated with an adaptogenic duo of purple laver and reishi mushroom, paired with high molecular weight hyaluronic acid, this facial serum intensely recharges the skin with water and reactivates its natural hydrating power. It helps counter daily environmental stressors — climate fluctuations, pollution — and delivers tailored hydration that holds for 72 hours, whatever the season or surroundings.
Adaptogen Rehydrating Serum is a watery-light serum from Payot. The formula is built mainly around hydration. The ingredient list runs to 17 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, Sodium Hyaluronate and Glycerin, 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, Sodium Hyaluronate, Glycerin and C15-19 Alkane.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Sodium Benzoate and Sodium Hyaluronate.
On richness alone it suits Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. A few ingredients carry irritation flags, so reactive skin should patch test before using it on the whole face.
The formula contributes little or nothing on barrier support, antioxidant protection, oil control and brightening and tone. 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, paraben-free, silicone-free, microplastic-free, sulfate-free and dye-free. Those claims come from the ingredient list itself, not from the packaging. It does contain fragrance and drying alcohol, 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.
