Take the skin testTackle acne, dark spots, and a weakened skin barrier with Isntree Onion Newpair B5 Ampoule. This potent formula is concentrated with 85% red onion extract and 5% panthenol to soothe blemishes and strengthen the skin barrier. Enriched with ferulic acid, caffeine, and allantoin, it tightens skin, evens skin tone, and provides deep hydration. The gentle formula, suitable for sensitive skin, also includes acetylglucosamine, tranexamic acid, and triple-hyaluronic acid for enhanced skin firmness and lasting moisture.
Onion Newpair B5 Ampoule is a watery-light ampoule from Isntree. The formula is built mainly around hydration and soothing. The ingredient list runs to 26 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 Panthenol, Trehalose and Betaine, 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 Panthenol, Trehalose, Betaine and Butylene Glycol.
Soothing: High. Ingredients aimed at visible redness and reactivity, and here that comes from Panthenol, Allantoin, Niacinamide and Acetyl Glucosamine.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Panthenol and Niacinamide.
Brightening: Moderate. Ingredients that act on uneven tone and post-inflammatory marks, and here that comes from Niacinamide, Tranexamic Acid and Acetyl Glucosamine.
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 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.

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.
