The history of Whoo Bichup Self-Generating NAD Power Ampoule

Ingredient analysis and how the ad lines read

What is this product?

The history of Whoo's Bichup Self-Generating NAD Power Ampoule is worth understanding before buying, because its headline number and its active are a thousand times apart: the brand advertises 50 percent NAD Power24, and the label discloses the NAD itself at 500 ppm, which is 0.05 percent. The label's own footnote settles what the rest of that 50 percent is, marking water, two solvents and four liposome-forming materials as members of the same named group. Behind it the formula is genuinely dense, 87 ingredients including niacinamide fifth, NMN, glycolic acid, six oligopeptides and six ferment extracts. Skip it if you avoid fragrance, because a fragrance plus six declared allergens close the list, and its one clinical figure, 33 percent barrier improvement, was measured using this ampoule together with a separate essence.

What makes it different?

Two things separate it, one substantive and one presentational. The substantive one is genuine formulation ambition: 87 entries carrying NAD at 500 ppm, NMN, niacinamide fifth, glycolic acid at 22, six oligopeptides, two palmitoyl peptides and six separate ferment filtrates, which is far more machinery than most ampoules attempt. Iron oxide and mica sit at 77 and 78, so there is a faint cosmetic tint supporting the makeup-grip positioning the brand leads with. The presentational one is the 50 percent figure, which describes a named complex whose first two members are water and dipropylene glycol, the first two ingredients in the product. Every performance figure the brand publishes comes without a participant count, a duration or a control arm, and the 3.6 times absorption comparison is against its own essence with no method given.

What is in it?

The full ingredient list as the brand publishes it, in the printed order. Each name links to what we know about that ingredient.

This brand publishes its ingredient list in Korean only. Names below are the matching INCI names from the Korean Cosmetic Association ingredient dictionary, except 9 with no dictionary entry, left in Korean.

Ingredients with no mark are ones we found nothing notable about, and when marks overlap on one ingredient we show the caution first.

We could not place these in the list above: 하이드로제네이티드레시틴, 돌콩오일, 솔비탄올리에이트, 피이지-8카프릴릭/카프릭글리세라이즈, 폴리솔베이트20, 솔비탄스테아레이트
