Vitamin C Serum Guide

What to Look For

Topical vitamin C, also referred to as L-ascorbic acid, is a topical antioxidant that has been shown to increase collagen production, smooth the appearance of fine lines and wrinkles and even skin discoloration, according to Skin & Aging magazine. The most important thing to look for when choosing skin serums containing vitamin C is the concentration. The serum must contain at least a 10 to 15 percent concentration of vitamin C to be deemed effective, according to Skin Care Guide.

Common Pitfalls

Vitamin C is an unstable compound, and when exposed to air it becomes ineffective and potentially harmful, because it may increase the production of free radicals, according to Smart Skincare. Skin care companies have introduced stabilized forms of vitamin C, but these serums can be costly.

Companies may also advertise that a serum contains vitamin C, but it's important to make sure the concentration is at least 10 percent.

How to Use Vitamin C Serum

Step 1

Select and purchase a vitamin C serum. According to Christine Dreher, a nutritionist, herbalist and author of "The Cleanse Cookbook," you should choose a serum with at least 10 percent concentration of L-ascorbic acid, also known as vitamin C.

Step 2

Wash your face with a clean wash cloth, a mild cleanser and warm water. Leave skin damp.

Step 3

Apply the vitamin C serum to your face and neck with your fingertips. Gently massage the serum into the skin. Wait three to five minutes for it to dry.

Step 4

Apply your normal moisturizer, preferably one that contains sunscreen. According to a study led by D. Darr at the North Carolina Biotechnology Center, antioxidant serums applied prior to sunscreen can improve the effectiveness of sunscreen against skin damage.

Step 5

Repeat the process twice a day.
