So you’ve finally decided you need a vitamin C serum—congratulations, you are one step closer to achieving a brighter, more youthful complexion. You’ve read all about the little-known benefits of this powerful antioxidant and even found out that Obagi Medical, one of the most renowned professional skin care lines, offers some of the best vitamin C serums out there. Still, you find yourself confused. What is L-ascorbic acid and what do those percentages mean?
Lucky for you, we’re here to demystify the science behind vitamin C and Obagi’s Professional-C Serum line. Here, we chatted with the experts at Obagi to answer seven of the most frequently asked questions about this line.
Question#1: What result can I expect from a vitamin C serum?
Answer: Vitamin C is essential for a healthy body, and therefore essential for healthy skin and hair. It’s a potent antioxidant that can neutralize free radicals, such as those found in environmental pollutants and after exposure to ultraviolet radiation. A vitamin C serum can do various wonders for your skin. Among the most noticeable benefits are the following:
- Even skin tone; diminished dark spots
- Reduced appearance of fine lines and wrinkles
- Brighter skin overall
Question#2: Why does Obagi prefer L-ascorbic acid over other forms?
Answer: Not all forms of vitamin C are created equal, and there are many derivatives on the market. Obagi uses L-ascorbic acid because it is known to be the most bioavailable (most absorbed by your skin) and thus most efficacious form.
Question#3: Why do Obagi Vitamin C serums come in different concentrations (10%, 15% and 20%)? What’s the difference and who should use which?
Answer: There are three percentages of L-ascorbic acid available in the Obagi Professional-C product line. A higher concentration isn’t necessarily better than a lower concentration; the difference is in intended use.
