Isntree Onion Newpair Ampoule Plus
Ingredient analysis and how the ad lines read
Read on 2026-09-06
What is this product?
Isntree's Onion Newpair Ampoule Plus is a 50ml whitening and anti-wrinkle serum built around 50,000 ppm panthenol and 874 ppm onion extract, with niacinamide, tranexamic acid and adenosine rounding out the functional actives. Isntree does not publish a pH or a concentration for the whitening actives themselves, and no clinical test was found for this specific product.
What makes it different?
The disclosed ppm figures for panthenol and onion extract are unusually specific for a Korean ampoule label, which is worth noting since most brands leave concentrations undisclosed. The whitening and wrinkle functional notice is stated on a third-party retail disclosure block rather than confirmed directly on the brand's own official page.
