Protect your skin from environmental and sun damage with these vitamin C serums. According to Nevada-based beauty chemist David Petrillo, vitamin C serums are rich in antioxidants that can protect the skin from environmental damage. They also brighten the complexion by stimulating collagen production and minimizing fine lines and dark spots. When incorporated into a morning skincare routine, vitamin C serums can enhance the effectiveness of other products like sunscreen and retinol serums. Generally, vitamin C is safe for all skin types and can help manage conditions such as acne and rosacea.
To help you find the perfect vitamin C serum, we tested 34 different products over six weeks. Each serum was evaluated based on ease of use, absorption, value, and its impact on skin texture and firmness. After the testing period, we reviewed our results to curate the best options. A dermatologist from our Medical Expert Board also verified this article for accuracy.
How Vitamin C Serums Work:
Triple board-certified dermatologist, Dr. Mamina Turegano, explains that vitamin C serums promote collagen production and address hyperpigmentation. It neutralizes free radicals, unstable molecules that can harm the skin and break down collagen, helping to prevent damage. It also evens out the skin tone. Dr. Yadav adds that vitamin C serums are suitable for all skin types and recommends daily use.
Choosing the Right Potency:
Vitamin C offers numerous benefits but can sometimes irritate sensitive skin due to its unstable antioxidant nature. Adrienne O’Connell, DO, suggests that those with sensitive skin should start with a lower potency serum to avoid irritation. Petrillo advises the same for individuals with melanated skin or those new to vitamin C products. Conducting a patch test is an effective way to ensure the product suits your skin.
What Healthcare Providers Want You to Know:
Best Practices:
Dr. Turegano recommends applying vitamin C serums in the morning, including a thin layer to your neck and décolletage. Dr. Yadav emphasizes that morning use provides optimal protection against free radicals, which your skin is most exposed to during the day. If you use retinol, Dr. Turegano advises applying it at night instead of in the morning when using your vitamin C serum.
Stable Forms of Vitamin C:
Dr. Turegano suggests looking for serums that contain L-ascorbic acid (the purest form of vitamin C) or tetrahexyldecyl (THD) ascorbate (a more stable form that penetrates deeper). For those with sensitive skin or prone to hyperpigmentation, she recommends choosing serums with L-ascorbic acid concentrations under 15% or sticking to THD ascorbate.
Antioxidant Boosters:
Since vitamin C can be unstable, Petrillo recommends pairing it with other antioxidants like vitamin E and ferulic acid. Dr. Yadav explains that vitamin E enhances vitamin C’s effectiveness, while ferulic acid helps stabilize it.
Natural Extracts:
Petrillo advises seeking out natural extracts like aloe vera or green tea, which can soothe the skin. He also suggests avoiding serums with artificial fragrances, essential oils, colors, or high alcohol content.
When to See a Healthcare Professional:
If you have skin conditions, Petrillo recommends consulting a dermatologist to ensure you’re using the right type and amount of vitamin C. Additionally, conditions like eczema can worsen with vitamin C use, so professional guidance is key.
