QAIRANG Daily Booster Vitamin C Plus Toner
Ingredient analysis and how the ad lines read
Read on 2026-09-23
What is this product?
A sap-first hydrating toner whose list opens with 자작나무수액 instead of water, with niacinamide at position 6 and a vitamin C derivative at position 16 for a brightening angle. It suits sensitive and dehydrated skin, though fragrance is included.
What makes it different?
The base is 자작나무수액 at position 1, with 정제수 pushed down to position 8, which is unusual for a toner. Niacinamide sits high at position 6 while Magnesium Ascorbyl Phosphate sits mid-list at 16, a gentle vitamin C derivative choice. Seven hyaluronic acid related ingredients occupy positions 19 through 27, giving layered hydration support. Fragrance appears near the end at position 28, which sensitive-skin users may weigh.

Did the ad claims hold up?
We checked 2 lines this product advertises against the ingredient list and public documents. None of them hold up on their own. They are partly right at best.
