Isntree Onion Newpair Ampoule Plus 50mL

An ampoule is a leave-on skincare step that sits after cleansing and toner, before moisturizer. Onion Newpair Ampoule Plus is the updated version of Isntree's original B5 ampoule, with a lighter, watery feel and a brightening-focused ingredient combination. The dropper bottle lets you dispense an appropriate amount without pouring.

The Plus formula combines 5% niacinamide with red onion extract, sodium ascorbyl phosphate and glutathione. Panthenol, betaine and three hyaluronic acid forms provide moisture, while squalane and ceramide NP add conditioning care. It is designed for uneven-looking tone and post-blemish discoloration, with a comfortable texture that the brand positions for sensitive, acne-prone skin.

An updated watery ampoule with 5% niacinamide

This is the Plus edition, not the original Onion Newpair B5 Ampoule. Its ingredient blend brings tone-focused care together with humectants and conditioning ingredients, rather than concentrating on a single brightening ingredient. The light consistency makes it an easy intermediate layer between toner and the moisturizer that completes your routine.

• 5% niacinamide: The brand identifies a five-percent concentration in the Plus formula, pairing this ingredient with red onion extract to care for uneven-looking tone and the appearance of dark spots.
• Red onion and antioxidant ingredients: Onion extract is accompanied by quercetin, ferulic acid and tocopherol. These complement the formula's brightening and skin-conditioning focus without adding a heavy oil texture.
• Vitamin C derivative and glutathione: Sodium ascorbyl phosphate and glutathione contribute to the tone-focused blend. The brand describes its glutathione component as a liposome ingredient.
• Moisturizing support: Panthenol, betaine, glycerin and three hyaluronic acid forms help maintain moisture, while squalane and ceramide NP add softening and barrier-supporting care.
• Lightweight dropper format: The watery formula spreads readily and is designed to absorb quickly. The 50mL dropper bottle provides controlled dispensing for a leave-on ampoule step.

Brighter-looking tone with everyday skin comfort

The ampoule combines care for uneven-looking tone with the comfort of a moisturizing serum. Its lightweight feel is useful when you want a targeted step but do not want another rich layer. The formula also includes soothing and conditioning ingredients to keep the routine focused on a comfortable skin surface.

• More even-looking tone: Niacinamide, the vitamin C derivative and glutathione help support a brighter appearance, addressing the look of dullness and lingering post-blemish discoloration.
• Hydrated softness: Humectants help the skin retain moisture, leaving the face feeling more supple rather than making tone-focused care a drying step in the routine.
• Comfort for dry-feeling areas: Panthenol, allantoin and madecassoside complement the moisturizing blend, helping support a calmer, more comfortable feel when skin is easily unsettled.
• A lighter intermediate layer: The watery texture avoids the weight of a dense ampoule and fits neatly under a finishing moisturizer in an uncomplicated daily routine.
• Balanced-looking finish: The combination of tone care and hydration helps the complexion look fresher and more uniform, without relying on a tinted or opaque coverage effect.
