Vitamin C is one of the most-studied skincare ingredients: an antioxidant that helps brighten dull skin, fade the look of dark spots, and even out tone over time. It's a daytime workhorse — and you genuinely don't need to spend a lot to get a good one.
We picked these five on formulation (a stable form of vitamin C, sensible concentration, supporting ingredients like vitamin E or hyaluronic acid) and on being easy to buy under $30. Results vary from person to person, so match the pick to your skin rather than the hype.

Apply in the morning after cleansing and before moisturizer and sunscreen. Vitamin C pairs especially well with daily SPF. If your skin is sensitive, start 2–3 times a week and build up. Store it somewhere cool and dark, since vitamin C degrades with light and air.
