Why it must
be this product
Do you know how to choose a vitamin C product properly?
Vitamin C can't be expected to work unless it's at pH 3.5.
Many vitamin C products are formulated at pH 5.0 or higher to reduce irritation, but in doing so they give up much of pure vitamin C's real efficacy. As the pH rises, oxidation accelerates and the effect drops off sharply.
Pure vitamin C (ascorbic acid) is most stable at pH 3.5, where skin penetration and antioxidant performance reach their peak.
DA99 is formulated to this optimal condition.
- Multiple clinical studies suggest pure vitamin C helps support firmness and brightening by supporting collagen synthesis and reducing melanin production.
Journal of Investigative Dermatology · International Journal of Molecular Sciences, and others - Studies show that vitamin C's stability and skin permeation are best near pH 3.5.

The DA99 Vita C Lifting Ampoule builds on the optimal pH 3.5 condition and adds a patented chitosan melting-thread essence.
It forms a lifting film on the skin and slows the oxidation of vitamin C — so you truly experience glow, firmness and improvement in fine lines.

The instant you apply it, the skin feels firmed and gently drawn taut.
