Improvement in the Appearance of Fine Lines

Vitamin C has been clinically studied and proven to improve the appearance of fine lines and wrinkles. In one 2017 study, consistent and daily use of vitamin C noticeably improved the look of fine lines and wrinkles on the face and neck.

Improvement in Skin Texture and Tone

In one double-blind dermatological study, daily use of vitamin C improved the overall appearance—particularly the texture and tone—of skin.

Increase in Collagen Production and Hydration

In that same double-blind study from 2002, biopsies showed an increase in collagen production, an improvement in hydration, and zero evidence of inflammation. Collagen production is directly linked to the firmness of skin, so this noticeable increase in the skin’s collagen production is impressive.

Reduction in the Appearance of Dark Spots

The appearance of dark spots can be improved with consistent vitamin C usage, suggests one clinical trial. The majority of participants in the trial saw a noticeable reduction in dark spots, with Vitamin C not only lightening the pigmentation, but also blocking the production of pigmentation altogether.

Vitamin C is incredibly sensitive to sun, heat, and light. Any exposure to these elements will cause it to become unstable and ineffective, notes one study. Look for a product that is in protective packaging, including tinted or completely covered—this will shield the product from light. And a pump, versus a dropper (which will expose the formula to the elements) is great, too.

Are There Skin Types That Should Not Use Vitamin C Serum?

While almost all skin types can benefit from using vitamin C skincare products, those with sensitive skin may experience redness or allergies. Begin by spot testing to ensure no negative irritation occurs, then incorporate a lower concentration of vitamin C into your skincare ritual and concurrently build up to the suggested usage on the packaging.
