How does vitamin C help your skin?

What is vitamin C?

Vitamin C, also called ascorbic acid, is a water-soluble vitamin and antioxidant. Your body needs it for many functions, including making collagen. In skin care, vitamin C is used in products such as serums, creams and moisturizers.

Antioxidants help neutralize reactive molecules created through normal body processes and environmental exposure. This does not make vitamin C a substitute for sunscreen or other proven skin care. It is one part of a routine, and the form and strength of a product affect how it should be used.

The benefits of vitamin C for your skin

Collagen is a protein that helps support the structure and elasticity of skin. Because vitamin C is involved in collagen production, it plays a role in maintaining normal skin. Collagen production naturally decreases with age, which contributes to changes such as fine lines and reduced firmness.

Vitamin C's antioxidant activity can also help protect skin from oxidative stress caused by factors such as sunlight and pollution. It cannot block ultraviolet radiation, so continue to use sun protection. Think of a topical antioxidant as support for your routine, not as a replacement for sunscreen.

Vitamin C products may brighten the appearance of skin and reduce the look of dark spots or uneven pigmentation over time. Results vary with the product, consistent use and the cause of the pigmentation. A changing, painful or otherwise concerning mark should be assessed rather than treated only as a cosmetic issue.

Choosing a vitamin C product

Vitamin C comes in several topical forms, including serums, creams and moisturizers. Labels differ in ingredient form, concentration, directions and storage. Start by reading the full label and following its frequency and application directions. Using more than directed does not guarantee a better result and may irritate your skin.

If your skin is sensitive, you already use several active skin-care ingredients, or you take medication that affects your skin, ask a pharmacist or another healthcare professional before adding a product. Introduce one new product at a time so it is easier to notice irritation.

Build a routine you understand

Keep topical products stored as directed and pay attention to colour, texture and expiry information. Stop using a product and seek advice if you develop a significant reaction. Persistent acne, rash, pigmentation or another skin concern may need an assessment rather than another product from the shelf.

A Revive pharmacist can help you compare over-the-counter skin-care products and check how they fit with your medicines. If you have broader questions about everything you take, bring your prescriptions, non-prescription products, vitamins and supplements for a medication review.
