Dot & Key's 10% Vitamin C + E serum is a popular brightening pick, but if you want the same core formula for less, The Derma Co 10% Vitamin C Face Serum is built on the same headline actives — 10% vitamin C paired with 5% niacinamide — from another dermatologist-led Indian brand, usually at a lower price and in a larger bottle.

Both serums share the same two headline actives at the same strengths — 10% vitamin C for brightening and antioxidant protection, plus 5% niacinamide to even tone and support the barrier. Dot & Key also lists vitamin E as an added antioxidant; The Derma Co keeps the formula fragrance-free and comes in a larger 30 ml bottle. For the everyday goal of a 10% vitamin C brightening serum, the two do the same job.
