Ingredient Investigation by Sephora:
Vitamin C

Beauty Pie, 2024

Meet your new holy grail.

Everyone drinks their vitamin C through orange juice, but did you know you can apply it to your face? This powerful active ingredient does wonders for your skin. If you’re struggling with dark circles, stubborn acne scars, hyper pigmentation, and uneven skin tone, vitamin C might become your new holy grail. Vitamin C comes in different concentrations, so even if you have sensitive skin, it’ll work for you. As an antioxidant, vitamin C helps protect your skin from sun damage, harmful pollutants in the air, and in general, helps with anti-aging. On Harvard Health, Dr. Neera Nathan and Dr. Payal Patel explained that “Clinical studies have shown that combining vitamin C with other topical ingredients, namely ferulic acid and vitamin E, can diminish redness and help protect the skin from long-term damage caused by harmful sun rays” (2021).

Vitamin C is most effective when used during the day time, and can be applied via eye creams, serums, and moisturizers. There are also makeup products infused with skincare ingredients like vitamin C. Be sure to use a sunscreen with high SPF when using vitamin C to protect your skin from any irritation from the sun, and watch out for any other active ingredients in your other skincare products that could cancel vitamin C out or combine to cause irritation.
