Why it worked
The video leverages a common skincare concern (Vitamin C serums) and presents a clear "buy or pass" decision framework, appealing to viewers seeking direct recommendations and ingredient-focused advice from a credible source (a pharmacist).
Summary
The video reviews several Korean Vitamin C serums, with the creator acting as a pharmacist. It evaluates Arencia, Dr. Althea, and COSRX serums, ultimately recommending the COSRX serum due to its high concentration of Vitamin C.

Original caption
🍊 BUY or PASS? Viral Korean Vitamin C Serums
❌ Arencia Vitamin C Booster Shot @Arencia
PASS. It clearly discloses 5% 3-O-ethyl ascorbic acid, but direct human evidence at this concentration is too limited for a treatment-focused vitamin C BUY.
❌ Dr. Althea Vitamin C Boosting Serum @Dr.Althea US
PASS. The exact vitamin C concentration is not clearly disclosed.
✅ COSRX The Vitamin C 23 Serum @COSRX Official
BUY. It contains 23% pure vitamin C, so it should still provide the established effects of high-strength L-ascorbic acid. There is no good evidence that 23% works better than 20%, and it may be more irritating.
❌ numbuzin No.5+ Glutathione Vitamin Concentrated Serum @numbuzin
PASS. Vitamin C is not the main active. This works better as a multi-ingredient dark-spot serum.
✅ mixsoon Vitamin C 20 Serum @mixsoon
BUY. It contains 20% pure vitamin C, within the best-supported high-strength range.
