It’s a powerhouse of a formula thanks to retinol, hyaluronic acid, niacinimide, salicylic acid and, of course, vitamin C. A little goes a long way, making the under-$20 price tag even better! Multiple reviewers like it for sensitive skin, acne-prone skin, and oily or combo skin times (reviewers with dry skin like it, too). Several people say it’s similar to the $182 SkinCeuticals vitamin C serum.

Promising reviews: “I actually heard of this product on TikTok. It’s a nice lightweight formula. Makes your skin so smooth and I’ve noticed a more even looking skin tone.” — Katelyn Hoffa

“I absolutely LOVE this serum. I was spending an absurd amount of money on SkinCeuticals products. This serum is way better. My skin is clearer and more bright. The only negative about this serum is the smell. It’s awful! I will tolerate it and continue to use it because of its effectiveness and price!” — Tish

“I am a licensed esthetician who deals with hormonal cystic acne that leaves scarring on my sensitive skin. My skin has improved so much since I started this!!! First, my skin purged out underlying blemishes but after was clearer + smoother than I’ve seen it in YEARS! I love that it not only targets my acne scarring with the vitamin C but also soothes the redness with the niacinimide, has retinol, AND helps minimize my blackheads and pore size with the salicylic acid. 😭 It is the perfect product for my sensitive oily acne prone skin!” — Jackie
