Take the skin test and I'll show you how suitable this product is for you.
Take the skin testThe Centellian24 Glutathione Toning Boosting Ampoule is a brightening treatment designed to improve uneven skin tone, enhance radiance, and restore a clear, luminous complexion. Powered by glutathione, a powerful antioxidant known for its skin-brightening benefits, this ampoule helps reduce dullness and support a more even-looking skin tone. Its lightweight, fast-absorbing texture delivers deep hydration while revitalizing tired skin. Formulated to boost clarity and glow, the Centellian24 Glutathione Toning Boosting Ampoule helps improve overall skin brightness while strengthening the moisture barrier. With continued use, it leaves the skin looking smoother, more radiant, and visibly refreshed.
Glutathione Toning Boosting Ampoule is a lightweight ampoule from Centellian24. The formula is built mainly around hydration. The ingredient list runs to 42 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Glycerin, Propanediol and Methylpropanediol, 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 Glycerin, Propanediol, Methylpropanediol and Water.
Soothing: Moderate. Ingredients aimed at visible redness and reactivity, and here that comes from Bisabolol, Niacinamide, Hippophae Rhamnoides Fruit Extract and Adenosine.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Tranexamic Acid and Ascorbic Acid.
Oil control: Moderate. Ingredients that moderate sebum or absorb shine, and here that comes from Niacinamide and Sodium Polyacrylate.
On richness alone it suits Balanced 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 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 fragrance-free, essential-oil-free, no drying alcohol, paraben-free, silicone-free and microplastic-free. Those claims come from the ingredient list itself, not from the packaging.
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.
