Do Vitamin C Serums Actually Work?

2. It Promotes Collagen Production

Vitamin C is also highly acidic – think of that tart orange juice you drink – and when applied topically it forces skin to “heal itself” and generate more collagen, a protein found naturally in our bodies that is vital to the healthy formation of bones, muscle, and skin. Unfortunately by the age of 25, our skin begins to drastically stop producing collagen, so any ingredient that stimulates production is going to help our skin look younger.

3. It Slows Down Melanin Production

Vitamin C can also slow down melanin production, which is responsible for our skin tone. This is what makes vitamin C popular in brightening products as it reduces age spots and other skin discolorations due to sun damage. Its daily use is also thought to prevent sun damage as well as repair it.

4. It Combines Well With Other Antioxidants

Vitamin C is often combined with other antioxidants, such as vitamin E and/or hyaluronic acid, both of which increase its efficacy and the stability of the compound itself. Stability is one challenge that skincare companies have had to overcome when introducing vitamin C serums to the marketplace. Exposure to air, light or heat can degrade its quality, this is why the serum bottles containing vitamin C are dark and opaque.
