Vitamin C is my favorite skincare ingredient. I have a dedicated morning routine that starts with a serum containing the brightening component, moisturizer, and sunscreen. As a shopping editor, I am lucky to get to test the latest and greatest as part of my job — and I will always jump at the chance to try out a new vitamin C product. All that to say I’m somewhat of an unofficial expert on what makes a great serum: It must check my boxes of sinking in without feeling sticky or greasy, actually brighten my complexion, and give me that “you naturally look awake and healthy” glow.
Fortunately for me (and you), InStyle did extensive testing this year on 33 top-rated vitamin C serums. We used the products daily for six weeks, then scored based on ease of use, absorption, and our appearance to find the very best ones. The best part? Three of our highest rated selects — plus a personal favorite of mine — are on sale at Amazon right now before the retailers Prime Big Deal Days — starting at $21.
L’Oréal Paris Revitalift 10% Pure Vitamin C Serum
The overall winner of our testing, L’Oréal’s Revitalift 10% Vitamin C Serum, is not only affordable, but efficacious, too. Our testers saw a brighter, firmer, and more awake appearance in just a few weeks of using the product. The thicker, cream-like formula adds a dose of moisture, too. Plus, the aluminum squeeze tube makes it simple to squeeze out every last drop of glowy goodness. I’ve finished tubes of this myself and commonly recommend this pick to friends; especially at the current $24 price point.
RoC Multi-Correxion Revive & Glow 10% Vitamin C Serum
The magic of this RoC serum compared to others is the texture — it has a jelly consistency that never leaves skin feeling tacky, just juicy. The 10 percent vitamin C formulation targets firmness, fine lines, dark spots, and dull skin, which is why we named it the best for anti-aging benefits. “My skin feels smoother, more hydrated, and [more] elastic after adding this serum to my morning skincare routine,” our tester said.
TruSkin Vitamin C Serum
Thanks to soothing, non-comedogenic ingredients like aloe vera, hyaluronic acid, and vitamin E, the TruSkin Vitamin C Serum is a great option for acne-prone skin. The serum has racked up more than 90,000 five-star ratings at Amazon thanks to how gentle (and effective) it is, and even White Lotus star Alexandra Daddario uses it for her sensitive skin. Plus, our reviewer confirmed that it’s sensitive-skin friendly. “As someone prone to acne, I love that this product doesn’t cause breakouts or clog my pores. I’m way more confident in stepping outside without makeup. I took a selfie after a 13 hour flight and my bare skin still looked bright and glowy,” she said.
Bliss Bright Idea Vitamin C Serum + Tri-Peptide Brightening Serum
A dermatologist-approved — and personally vetted — pick is the Bliss Bright Idea Serum. The formula not only gives you a bright, dewy complexion but has anti-aging benefits as well. “The vitamin C and peptide serum delivers a stabilized form of vitamin C to the skin and also contains a peptide to help strengthen the skin barrier,” NYC-based dermatologist Joshua Zeichner MD tells InStyle. This serum sits really nicely on the skin and never pills when you layer on SPF or foundation. “I’ve been using this for a couple years, and my skin has never looked better!” said one Amazon reviewer. “It’s very hydrating, and my skin looks noticeably younger and healthier than it did before I started using it. Love the orange scent, too.”
