At under $10 this is the most budget-friendly way to get a high concentration of L-ascorbic acid, and the water-free suspension keeps it stable without a fancy bottle. The texture is thick and slightly gritty, so I'd apply it alone and let it absorb ...
The Ordinary Vitamin C Suspension 23% + HA Spheres 2%
This is one of the lowest-priced true L-ascorbic acid serums you will find, and 15 percent is a concentration that actually counts. The lightweight serum texture layers well under moisturizer and absorbs quickly without leaving a residue.
The INKEY List 15% Vitamin C and EGF Serum
This long-running bestseller uses sodium ascorbyl phosphate, a gentler and more stable vitamin C form that suits people whose skin gets reactive with straight L-ascorbic acid. It layers in hyaluronic acid and vitamin E, so you get a hydrating, non-st...
TruSkin Vitamin C Facial Serum, Anti-Aging Blend for Brighter-Looking Skin with Soothing Squalane, 1 fl oz
A 22 percent blend of vitamin C forms with turmeric and it is completely fragrance free, which I appreciate at any price point. The serum has a fluid, fast-absorbing texture that plays nicely under SPF without pilling.
Naturium Vitamin C Complex Serum
A 22 percent vitamin C blend with ferulic acid and vitamin E at $26, fragrance free, and the serum has a silky texture that layers under makeup without a problem. This is one I'd reach for if you want the antioxidant stack without paying luxury price...

Twelve percent pure vitamin C with vitamin E and salicylic acid, fragrance free, and available at any drugstore or Walmart for around $28. The lightweight serum absorbs cleanly and the formula is well-tolerated for a straight L-ascorbic acid option a...
L'Oreal Paris Revitalift 12% Pure Vitamin C Serum, Brightening Serum for Face with Vitamin E, Salicylic Acid, 1 fl. oz.
This is the drugstore answer to the gold-standard vitamin C plus E plus ferulic acid formula, at $28 and sold in an airless pump that actually keeps the formula stable. Twenty percent L-ascorbic acid is on the higher end of what I'd recommend, so if ...
Timeless Skin Care 20% Vitamin C + E Ferulic Acid Serum
Ten percent L-ascorbic acid paired with ceramides and vitamin B5 makes this a solid option if you want brightening actives without stripping the skin barrier. The gel serum texture is lightweight and non-greasy, and CeraVe's price point makes it easy...
CeraVe Skin Renewing Vitamin C Serum, Brightening Antioxidant Serum for Dull Skin, 1 fl oz
Ten percent pure vitamin C with salicylic acid and neurosensine in a packaging format designed to limit oxidation. La Roche-Posay tends to formulate with sensitive skin in mind, and this one absorbs quickly without the sticky or tacky finish some vit...
La Roche-Posay Vitamin C12 Face Serum, Vitamin C Serum with Salicylic Acid, 1 fl oz
Sodium ascorbyl phosphate with ferulic acid, vitamin E, and konjac root in a gentle formula that works well for people who want a stable vitamin C without the irritation potential of high-dose L-ascorbic acid. The texture is lightweight and the ingre...
Mad Hippie Vitamin C Serum
Twenty percent vitamin C paired with ten percent AHAs from fruit makes this a two-in-one brightening and resurfacing serum at $34. The texture is silky and it layers beautifully, but because of the AHA content I'd skip any other exfoliating actives o...
Tatcha Violet-C Brightening Serum
Five forms of vitamin C alongside tranexamic acid and ferulic acid at $45 puts this near the top of the under $50 range, and the gel texture feels genuinely enjoyable to apply. It is a good pick if you want a vitamin C serum that also brings tranexam...
