If you've got oily skin then you've probably got the acne scars to prove it. But thank god for vitamin C, because it does wonders for us (yes, this is me too). Not only does vitamin C help fade hyperpigmentation and aid in skin brightening, it can also help clear up redness, destroy acne-causing bacteria and prevent acne scars.

My personal favorite is Cosrx's Triple C Lightning Liquid, $27. With 20.5 percent pure vitamin C it works hard to reverse hyperpigmentation and lighten brown spots and acne scars. It's a simple yet powerful formula with added black chokeberry and licorice root that helps bring radiance back to your skin.

Tip: be careful when mixing vitamin C with exfoliating acids like AHAs, BHAs, and retinol. Using these together can lead to skin irritation. Instead try switching off days that you use each product. Or use you vitamin C in your morning routine — especially since it can fight against environmental damage and UV rays (still, make sure to use your SPF!).
