When it comes to tackling signs of skin aging, vitamin C is an essential ingredient to incorporate in your skincare regimen.

How vitamin C works on the skin:

Vitamin C is a powerful antioxidant that can be found in sources such as citrus fruits and leafy green vegetables. The most effective form of vitamin C on skin is L-ascorbic acid1. When our skin is exposed to UV light, pollution or other environmental stressors, reactive oxygen species or free radicals are formed and may cause damage to the skin cells. This in turn leads to signs of skin aging (i.e. sun spots, fine lines and wrinkles). Vitamin C helps protect the skin of damage from oxidative stress by neutralizing free radicals.

Skin benefits of vitamin C:

  1. Sun damage: Use of Vitamin C may help prevent signs of premature skin aging by reducing visible UV-induced skin redness.
  2. Brightening dull skin: Vitamin C works to help brighten dull skin complexion. Vitamin C may be used in different skin types and in skin of color for tackling uneven skin tone.
  3. Skin texture benefits: Vitamin C may be beneficial for many different skin types in promoting even texture.

Who can use vitamin C?

When it comes to choosing skincare products, understanding if the ingredient is safe to use for your skin type and your skin concern is key.

Uneven skin tone: Vitamin C is frequently incorporated in various skin brightening topicals given its skin brightening benefits. Vitamin C, as mentioned above, helps to reduce pigment production, brighten dull skin complexion and even uneven skin tone2.

Blemish-prone skin: Vitamin C is frequently added to various serums. When it comes to choosing a vitamin C serum that is beneficial for blemish-prone skin, look for a serum that contains other hydrating and soothing skin ingredients, such as hyaluronic acid, ceramides, vitamin E and glycerin2.

With so many vitamin C products out there, it is important to be a proactive and educated consumer when it comes to choosing the best vitamin C product. The key to choosing a Vitamin C serum is to look for serums that contain L-ascorbic acid, the most efficient form of Vitamin C2, such as La Roche-Posay’s 10% Pure Vitamin C Serum. Vitamin C is a key anti-aging skin care ingredient and looking for vitamin C-containing topicals is a helpful first-step to promoting and maintaining radiant, healthy looking skin.
