Isntree Onion Gel Cream Plus
Ingredient analysis and how the ad lines read

Read on 2026-09-06
What is this product?
Pick this 50ml gel-cream if you want post-blemish tone care with receipts where they matter most: it holds Korea's dual functional registration for both brightening and wrinkle improvement, names its onion extract at a disclosed 10,100 ppm, and keeps all 50 ingredients free of fragrance, essential oils and drying alcohol. Do not expect proven results though, because Isntree publishes no test of any kind for it, hides every other active's amount, and the registration certifies ingredient inclusion rather than measured outcomes. Its light gel texture suits oily or combination skin better than very dry skin, which will likely need something heavier on top in winter.
What makes it different?
Few creams in its class print an exact figure for their title ingredient; this one does (onion extract, 10,100 ppm) and pairs it with whitening-notified niacinamide high in the list, wrinkle-notified adenosine, and five separate hyaluronate forms. It comes in 50ml and 80ml sizes.
