FAQs

How long does it take for vitamin C to fade acne scars?

In the case of post-inflammatory hyperpigmentation, how long it takes for these marks to fade differs from person to person, and also depends on the severity of the mark. How diligent you are with applying your vitamin C serum also affects how quickly it will work. Generally, if you're consistent with your application, you should start to see improvement in your post-inflammatory hyperpigmentation in about 3 weeks. For pitted or raised acne scars (where the actual texture of the skin is changed, rather than just the color), vitamin C may help minimize their appearance over time, but these scars often need a professional treatment to completely get rid of them.

Can I use a vitamin C serum everyday?

Yes, you can use a vitamin C serum everyday. Regular application will help you fade your acne scars more quickly. However, some people may find that using a vitamin C serum on a daily basis may irritate their skin. This is especially true for serums that contain a high concentration of vitamin C. If this is your first time using a vitamin C product in your routine, consider applying it every other day to allow your skin to adjust to the ingredient. After a few weeks, you can increase to daily usage, if it seems suitable for your skin.

What can you not mix with a vitamin C serum?

Since vitamin C is such a powerful skincare ingredient, you often shouldn’t mix a serum with a high concentration of this vitamin with other products containing powerful active ingredients. Some ingredients will actually counteract the effects of vitamin C, while others will just increase your risk of irritation. When you apply a vitamin C serum, you should avoid applying products with AHAs or BHAs (like glycolic acid, lactic acid, and salicylic acid), retinol, or benzoyl peroxide. If you use products with these ingredients in your routine, simply apply them at different times. For example, apply a vitamin C serum in the morning, and retinol at night.

The Bottom Line

With consistent usage, the right vitamin C serum can help you minimize the appearance of acne scars for a more even complexion. Consider adding one of these effective serums to your routine to get rid of annoying acne scars once and for all.
