These 53 Inexpensive Alternatives To Popular Products Are So Good, You Will Never Buy The Pricier Version Again

When it comes to vitamin C, this formulation is on the stronger side, so you should do a patch test before using! And make sure you use SPF after (tbh as you should every morning)! Though the bottle looks small, reviewers say it’ll last you several months with daily use.

Promising review: “I love this product so much. In only five days, my skin is smoother, clearer, and tighter. On the second day, my skin was a bit warm and red, so I skipped a day and have been using it every day without any more irritation. I find this just as effective and WAY less stinky than Skin Ceuticals. I highly recommend giving it a try.” —Alex

Promising review: “I should have started using this years ago! I’m in my mid-30s, and I’ve tried everything, including much more expensive brands, Korean skincare, Japanese skincare, etc., but I’ve always had breakouts and problems with texture. This is by far the best vitamin C product I’ve tried. I’ve tried multiple vitamin C serums in the past, but they always broke me out or had a slimy or gritty texture. This serum has a smooth texture, soaks in quickly, does not pill with other products, and has noticeably cleared up my skin.” —Amazon Customer
