The Derma Co5% Vitamin C Daily Face Serum

The Derma Co's gentlest vitamin C serum uses 5% 3-O-ethyl ascorbic acid, a stabilised vitamin C derivative, with ferulic acid, a multivitamin blend and dimethyl isosorbide, which the brand includes to help the serum absorb. It is fragrance-free and comes in a 30 ml dropper bottle. Price, size and rating were read together from the brand's own store: 472 rupees in a sitewide sale against a 549 rupee MRP, rated 4.83 from 133 reviews. A lower strength like this suits beginners or sensitive skin better than the brand's 15% and 20% serums. Ratings on a brand's own store tend to run higher than on open marketplaces.
