Vichy LiftActiv Vitamin C Serum Review
Now, for the differences:
- Vichy uses pinus pinaster bark extract (a.k.a. Pycnogenol), rich in plant antioxidants and derived from French Maritime pine trees, instead of 0.5% ferulic acid
- Vichy uses hydrolyzed hyaluronic acid, a lower molecular weight and "chopped up" version of its bigger brother, hyaluronic acid, instead of sodium hyaluronate
- Vichy is miles more affordable versus SkinCeuticals (twice the price!) plus the smaller bottle size limits vitamin C oxidation
Unfortunately, Vichy doesn't disclose the pH (one customer said it's 2.5) whereas SkinCeuticals is formulated at a pH between 2.0-3.5, in line with the Duke Antioxidant Patent.
Nonetheless, I'd bet that Vichy is using a pH below 3.5 since research has shown it's required for L-ascorbic acid to effectively penetrate your skin barrier (Pinnell, 2001).
Our Verdict: With over 7K+ reviews, Vichy Liftactiv Vitamin C Serum is our Editor's Choice because it's simple, effective, and affordable for everyone! Featuring 15% pure vitamin C, vitamin E, pine bark extract, and hyaluronic acid, this popular vitamin C serum is almost identical to the world-class SkinCeuticals C E Ferulic for a fraction of the price.
