Vitamin C has many essential functions inside and outside the body. According to Allure's Readers' Choice Award survey, vitamin C serums are the most sought-after skincare products in the beauty industry. How exactly does vitamin C help the skin? Do we rub orange juice on the body? Luckily dermatologists have shared their expert knowledge about the benefits of vitamin C for the skin. Forbes, Allure, and Byrdie have published articles explaining why vitamin C is an effective skincare product.

What is Vitamin C, and how does it work?

The pure form of vitamin C is Ascorbic acid, a nutrient in many fruits and vegetables. The beauty industry uses several derivatives of this acid in skincare products. Derivatives are pure vitamin C combined with other ingredients to maintain stability, according to a cosmetic chemist and founder of BeautyStat Cosmetics, Ron Robinson. The variant of vitamin C varies in pH and releases pure vitamin C when in contact with the skin.

Dr. Patricia Wexler, M.D., a board-certified dermatologist, describes vitamin C as a 'potent antioxidant.' Topical antioxidants aid in the natural repair process of damaged skin cells and neutralizes harmful reactive oxygen species (ROS), a type of free radicles. ROS damages the dermis of the skin and alters DNA. Renée Rouleau, celebrity esthetician and founder of her eponymous skincare brand, constructed an experiment to explain how Vitamin C protects cells.

He cut a slice of apple, sprayed one half with vitamin C serum, leaving the other half normal. The half without vitamin C serum after three hours turned brown after oxidation. His experiment proved the protective action of vitamin C on cells.

Vitamin C undergoes irreversible chemical changes when exposed to air, light, and heat. It's necessary to store serums in air-tight, opaque bottles and a cool place.

What does Vitamin C do for the skin?

1. Vitamin C protects against environmental stressors

Your skin is exposed to many forms of free radicals in the environment, which cause harm to cells. Elements such as UV light, smoke, and even stress generate free radicals. free radicals damage cells, promoting skin dullness, wrinkles, and even cancers." Dr. Anna Guanche explains. Vitamin C's role as an antioxidant protects skin cells from these harmful effects and decreases the rate of aging. Joshua Zeichner, M.D., the director of cosmetic and clinical research at Mount Sinai Hospital in New York City, added that vitamin C can help to protect the skin from precancerous changes from UV exposure. According to Tiffany Masterson, the founder of Drunk Elephant, vitamin C serums works best when used under sunscreen lotion. The best feature of this serum is it can be used on any skin type for an extended period, without side effects.

2. Vitamin C promotes collagen synthesis.

Vitamin C plays an active role in the production of collagen and elastin says Dr. Howard Sobel, M.D. Ascorbic acid is a cofactor for two essential enzymes needed for collagen production, they are:

  • prolyl hydroxylase, for collagen molecule stability
  • lysyl hydroxylase, for structural strength

Collagen fibers are protein in the skin that helps to keep it plump and firm, reducing visible signs of aging.

3. Vitamin C lightens dark spots.

According to Drs. Guanche and Jennifer Herrmann vitamin C can lighten dark spots by blocking the pigmentation synthesis pathway. Whether the pigmentation resulted from a post-inflammatory reaction or sun exposure, vitamin C can inhibit melanin production, stopping the pigmentation. Dr. Wexler advises that continuous topical use helps prevent the formation of dark spots.

"It's a superior brightening agent that works to fade brown spots without altering normal skin pigmentation," -Dr. Sober.


Vitamin C serums are indeed assets to your skincare routine. Vitamin c's ability to lighten dark spots and promote collagen synthesis makes it a superior skincare product. Vitamin C also has minimal to no side effects on all skin types and works as an antioxidant. Several dermatologists have written about their support of vitamin C serum.
