Why You Need Vitamin C for Your Skin

Vitamin C is not only good for your immune system, but also for your skin. This powerful antioxidant has many benefits that can improve your skin health and appearance. In this blog post, we will explain what vitamin C does for your skin, how to use it, and what to look for in skincare products.

What Does Vitamin C Do for Your Skin?

Vitamin C, also known as ascorbic acid, is a water-soluble nutrient that plays an important role in keeping your body and skin healthy. When applied topically, vitamin C can:

  • Boost collagen production: Collagen is the building block of skin, hair, muscles, and tendons, and it is what keeps our skin looking youthful and smooth. As we age, collagen production slows down, which may lead to sagging skin. Vitamin C accelerates the production of both collagen and elastin, which help keep the skin plump and firm.
  • Reduce the appearance of dark spots: Vitamin C may help improve skin complexion by reducing the appearance of hyperpigmentation, a common condition characterized by the development of darker spots on the skin. Hyperpigmentation is most often caused by overexposure to the sun’s ultraviolet (UV) rays and environmental stresses. Vitamin C helps inhibit the production of tyrosinase, an enzyme that aids in the production of melanin, preventing hyperpigmentation. Vitamin C doesn’t have an effect on normal skin coloration—it won’t fade away normal dark skin pigmentation, only the abnormal melanin deposits caused by excess sun exposure.
  • Reduce the appearance of early aging: Topical vitamin C can help prevent premature aging of the skin, restoring a youthful, smooth appearance to the skin. Not only does vitamin C boost collagen production, which can reduce wrinkles and increase elasticity of the skin, but it also help prevent the loss of collagen that results from natural aging. In addition, this antioxidant plays an important role in combating unwanted dark spots and preventing signs of premature aging caused by factors such as smoking, environmental pollutants, and chronic sun exposure.
  • Protect against sun damage: Studies show that vitamin C in the skin can help protect against UV damage. Exposure to UV radiation from the sun (as well as tanning beds) can create free radicals in the skin, which may damage skin cells and lead to the breakdown of collagen. Vitamin C neutralizes these free radicals and may also enhance the effectiveness of sunscreen by boosting its SPF. However, vitamin C is not a substitute for sunscreen and should be used in combination with a broad-spectrum sunscreen with at least SPF 30.
  • Promote wound healing: Vitamin C may also help with wound healing by stimulating the formation of new blood vessels and collagen in the injured area. Vitamin C also has anti-inflammatory properties that can reduce swelling, redness, and pain associated with wounds.
  • Keep the skin hydrated: Vitamin C can help the skin retain moisture by increasing the production of ceramides, natural lipids that form a protective barrier on the skin surface. Ceramides prevent water loss and keep the skin hydrated and soft.
  • Reduce redness: Vitamin C can also help reduce redness and inflammation in the skin by inhibiting the release of histamine, a chemical that causes allergic reactions and irritation. Vitamin C may also improve the appearance of rosacea, a chronic skin condition that causes redness, flushing, and bumps on the face.

How to Use Vitamin C for Your Skin

Vitamin C can be found in various skincare products, such as serums, creams, lotions, masks, and cleansers. The most effective way to use vitamin C for your skin is to apply it topically, as oral supplements may not reach the skin in sufficient amounts. Here are some tips on how to use vitamin C for your skin:

  • Choose the right product: Different formulations of vitamin C can alter its strength and effects in the skin. Consider purchasing vitamin C products from reputable brands or verified online retailers, with a clinical formulation that contains an active form of vitamin C (for instance, L-ascorbic acid), has a strength of 10% to 20%, and a pH lower than 3.5, as this combination has been studied in clinical trials. You can check the ingredients list and the manufacturer’s website for this information.
  • Apply it in the morning: Vitamin C is best applied in the morning, as it can help protect your skin from sun damage and environmental stressors throughout the day. You can also apply it at night, but make sure to use a gentle cleanser and moisturizer afterwards, as vitamin C can make your skin more sensitive.
  • Use a thin layer: A little goes a long way with vitamin C. You only need a few drops of serum or a pea-sized amount of cream to cover your entire face and neck. Gently massage the product into your skin until it is fully absorbed. Avoid the eye area, as vitamin C can cause irritation.
  • Store it properly: Vitamin C is unstable and can degrade when exposed to light, heat, and air. To preserve its potency and shelf life, store your vitamin C products in a cool, dark, and dry place, preferably in an opaque or amber-colored container. You can also keep them in the refrigerator for extra protection. Discard any products that change color, smell, or texture, as this indicates oxidation and loss of effectiveness.


Here are some frequently asked questions about vitamin C for skin:

  • How long does it take to see results from vitamin C?: The effects of vitamin C may vary depending on your skin type, condition, and product. Generally, you may start to notice some improvement in your skin tone, texture, and brightness within a few weeks of consistent use. However, it may take several months to see significant changes in your wrinkles, dark spots, and sun damage.
  • Can I use vitamin C with other skincare ingredients?: Vitamin C can be safely combined with most skincare ingredients, such as hyaluronic acid, niacinamide, peptides, and retinol. However, some ingredients may interfere with the absorption or stability of vitamin C, such as benzoyl peroxide, salicylic acid, and alpha hydroxy acids (AHAs). If you use these ingredients, apply them at different times of the day or wait at least 30 minutes between applications.
  • Are there any side effects or risks of using vitamin C?: Vitamin C is generally well-tolerated and safe for most skin types. However, some people may experience mild irritation, stinging, burning, itching, or redness when using vitamin C, especially if they have sensitive skin or use a high concentration or low pH product. To avoid or minimize these reactions, start with a lower strength product, use it every other day, and apply a moisturizer afterwards. If the irritation persists or worsens, stop using the product and consult your dermatologist.
  • Who shouldn’t use vitamin C products?: Vitamin C has only been studied in adults and is not recommended for children. People who are allergic to vitamin C or any of its derivatives should avoid using vitamin C products. People who have certain skin conditions, such as eczema, psoriasis, or dermatitis, should consult their dermatologist before using vitamin C products, as they may cause further irritation or inflammation.


Vitamin C is a versatile and beneficial ingredient that can help you achieve healthy and beautiful skin. By using vitamin C products regularly and correctly, you can enjoy its many benefits, such as boosting collagen, reducing dark spots, preventing sun damage, and more. However, remember that vitamin C is not a miracle cure and should be used as part of a comprehensive skincare routine that includes cleansing, moisturizing, and sun protection. If you have any questions or concerns about using vitamin C for your skin, don’t hesitate to contact your dermatologist for advice and guidance.
