A dermatologist explains why vitamin C should be in your skincare routine

(BPT) - Are you always on the lookout for better, more effective — and affordable — ways to help boost your skin's health and appearance? If so, you've probably noticed that vitamin C has become a staple when it comes to top ingredients in the best skincare products. You’ve also probably heard dermatologists consistently recommending the topical application of vitamin C as a crucial part of their patients' everyday skincare routines. But why? And when should you use it?

What vitamin C can do for your skin

New York City Dermatologist Dr. Joshua Zeichner explains some of the reasons why this vitamin should be at the top of your skincare regimen to-do list.

"Vitamin C, technically known as ascorbic acid, has become so popular because it is the best-studied topical antioxidant on the market to treat the skin. It neutralizes free radical damage to help repair and protect your skin at the cellular level. It also helps even out skin tone and brighten dark spots," said Dr. Zeichner. "Adding a skincare product with vitamin C to your routine can give the skin a glowing, radiant appearance."

With many skincare products on the market now featuring vitamin C, it's important to find the right products, as well as a skincare regimen that's best for you.

"I recommend looking for products that have been clinically tested and approved by dermatologists," said Dr. Zeichner. "Vitamin C can be used in the morning along with sunscreen to help protect the skin. It can also be used in the evening along with your nighttime moisturizing cream to help repair it."

Here’s an easy and affordable 2-step routine that can help you bring the power of vitamin C into your daily skincare regimen.

Step 1: RoC Multi Correxion Revive + Glow Daily Serum

After gently cleansing your skin, apply this potent, lightweight serum, which is supercharged with a daily dose of vitamin C. One hundred percent of testers experienced brighter and tighter skin in just 4 weeks, along with a reduction in fine lines and wrinkles — and 94% had a more even skin tone.

The serum contains a 10% active Vitamin C Antioxidant blend that include Peptides and Advanced Hydrators to visibly brighten skin, improve elasticity and reduce the look of lines and wrinkles.

Step 2: RoC Multi Correxion Revive + Glow Gel Cream

For your second step after applying the serum, this gel cream has a potent vitamin C blend that's great for supporting your skin's health. In clinical tests, 97% of testers instantly saw more luminous, plumper-looking skin, and 100% experienced brighter skin and improved elasticity in just four weeks.

Both of these products are clinically proven, dermatologist-tested and both paraben- and sulfate-free.

"One important note is that vitamin C and retinol should not be mixed. If you use retinol products at night, then use the vitamin C products only in the morning," added Dr. Zeichner.
