Ingredient analysis and how the ad lines read

Read on 2026-09-26

What is this product?

Arencia Vitamin C Booster Shot is a 30 mL gel serum in a nozzle tube, filed in Korea as a whitening and wrinkle improvement functional cosmetic. Its printed list puts 3-O-ethyl ascorbic acid fourth at 50,000 ppm, about 5 percent, with a trace of ascorbic acid, two more vitamin C derivatives, niacinamide, adenosine and glutathione; there is no fragrance entry and no exfoliating acid. The brand prints a low irritation score and one before and after pair without figures. Suited to people wanting a spot and all-over vitamin C serum for uneven tone.

What makes it different?

A tube vitamin C serum whose printed list states the main vitamin C form's amount, 3-O-ethyl ascorbic acid at 50,000 ppm in fourth place, paired with glutathione and a whitening and wrinkle functional filing, meant for spot layering as well as all-over use.
