We sorted through hundreds of vitamin C serum products to narrow down the top ones to test. These are the best vitamin C serums to try now.
Vitamin C serums are seemingly everywhere and for good reason—this powerhouse antioxidant and skin brightener is one of the most effective skincare ingredients out there. But vitamin C is notoriously fickle. It can degrade and lose its potency over time or when exposed to light and heat.
Our team of researchers and testers researched and tried hundreds of vitamin C serums on the market to find the best of the best. Testers looked at various factors, including company ethics, quality, efficacy, results and value. They also looked for the most effective forms of vitamin C and other anti-aging ingredients. These “Top 5” vitamin C serums stood out.

This is their top seller and for a good reason! The Super C Serum rejuvenates skin by reducing the appearance of wrinkles and age spots. It also moisturizes, brightens, evens out skin tone, lifts, and firms. This silky smooth all-in-one serum is a true multi-tasker. Their Vitamin C formula is superior than standardized Vitamin C. They also add Hyaluronic Acid, Vitamin B5, Vitamin E, and other key ingredients that make Vibriance Super C Serum an all-in-one multitasker that's gentle enough for the most sensitive of skin while also delivering noticeable results.
Seratopical Gleaming Brightener is the new holy grail in skin transformation with its powerful triple peptide blend of P3P, Licorice Root Extract, and Coriander Seed Extract. These ingredients are primarily famed for improving the skin's texture, diminishing the appearance of dark spots and age spots, along with helping collagen and elastin regeneration and improving skin suppleness and strength.
C E Ferulic serum is one of SkinCeuticals’ most popular products, with a loyal following of aestheticians and dermatologists. Its patented formula provides environmental defense, brightens the skin and helps to improve the appearance of fine lines and wrinkles.
C E Ferulic serum is a clinically tested, award-winning formula with many positive reviews online. Along with vitamin C, vitamin E and ferulic acid, it also contains hyaluronic acid to hydrate the skin.
However, this SkinCeuticals serum contains only 15% L-ascorbic acid (vitamin C). This is less than our top pick. It also skips retinol and botanicals. And at the steep price of $166 per ounce, this cost-prohibitive option is not accessible to all users.
SkinMedica Vitamin C + E Complex is one of the simpler formulas we researched, with a focus on vitamins C and E. Our testers liked that it contains two forms of vitamin C: ascorbic acid and tetrahexyldecyl ascorbate. The company states that it delivers this vitamin C to the skin gradually to offer all-day protection.
However, testers also noticed that this serum does not contain ferulic acid. Ferulic acid is widely believed to support the stability and effectiveness of vitamin C formulations. Without it, we have concerns about this formula’s potency and stability.
Also, this serum is not available for sale online, so buying it requires a trip to a dermatologist, aesthetician or plastic surgeon.
Testers had high expectations for this serum from Clarins, a historic French beauty brand. Double Serum is one of the brand’s best-selling products, first produced in the early 80s and reformulated multiple times.
Double Serum contains 21 plant extracts, including turmeric, avocado and goji berry and some unique ingredients like the leaf of life plant. The company reports that this serum firms, moisturizes and increases radiance. However, it doesn’t contain the clinical ingredients we like to see in a serum, such as retinol or hyaluronic acid. And it contains artificial fragrance, which we prefer to avoid.
