"I was looking to incorporate a vitamin c into my routine to help with my acne scars, and this stuff is insanely good! I received a mini size to test out and one pump goes a long way. After about three weeks, I noticed my forehead and cheek scars were less visible, my overall skin texture improved, and my face was glowing! I have sensitive skin and this didn't make it purge or breakout. I'm so happy with this product." —Jessicah78

When is the best time to apply a vitamin C serum?

According to experts, the best time to apply a vitamin C serum is in the morning on clean, dry skin before using at least an SPF 30. Patel adds, "Vitamin C helps to compound the protection of your SPF.”
Which products should you avoid when using a vitamin C serum?

As some vitamin C serums can be extra potent in your routine, it's not surprising that it doesn't always play well with other ingredients. "Using too many products with exfoliating agents, such as AHAs, retinol, and vitamin C all at once can make the skin peel and lead to sensitivity. Using only one active ingredient at a time helps minimize this," Patel explains. If you're concerned about using products with these ingredients, try using them at night, and vitamin C in the morning.
