Vitamin C Serum
Vitamin C Serum
“Vitamin C is a potent antioxidant that brightens dark spots, smooths fine lines, and, importantly, scavenges free radicals from the environment, pollution, and UV radiation,” Sara Hogan, M.D., dermatologist at UCLA Medical Center, Santa Monica, tells SELF. Over time, those free radicals can damage the skin, leading to premature signs of aging, and increase your risk for skin cancer. So protecting against UV damage with an antioxidant—and, of course, daily SPF—is important.
However, not all vitamin C products are created equal—and they can be irritating and finicky to use in some cases, Angela Lamb, M.D., director of Westside Mount Sinai Dermatology Faculty Practice, tells SELF. It’s important to read the label on the product and know what you’re really getting (which isn’t always an easy feat when it comes to over-the-counter products), especially if you have sensitive skin. below you can see vitamin c serum before and after.
How to use a vitamin C serum
Although topical vitamin C is generally well-tolerated, all skin products have the potential to cause side effects. You should always do a patch test to assess your risk for allergic reaction. Here’s how:
Select a small area of skin that’s easy to conceal, like your forearm.
Apply a small amount of product and wait 24 hours.
If no side effects occur, you can apply to your face. Discontinue use if you develop a rash, redness, or hives.
When it’s time for a full application, follow the instructions on the product’s label.
Vitamin C serum is typically applied once or twice per day. A good rule of thumb is to cleanse, tone, apply vitamin C serum, and then moisturize.
It can be safely used in conjunction with other active ingredients, although use alongside niacinamide may render vitamin C less effective.
