Vitamin C can be fickle — for instance, it doesn't generally mix well with other acids (retinoids, AHAs, BHAs, etc), and it can also cause skin sensitivity and irritation. But don't let that scare you off! Not all vitamin C products are created equal; there are different kinds that have varying concentration of vitamin C and others that add on soothing, boosting and hydrating benefits too.
In other words? There's a vitamin C out there for everyone — and one that will work great, just for you! Here are some suggestions for your skin type.

Vitamin C for Sensitive/Dry Skin
A bonus: this serum has niacinamide! When paired together, these ingredients give you an extra boost of benefits for more radiant-looking skin.
Tip: when looking for a vitamin C for sensitive skin aim for a product with less than 20 percent L-ascorbic acid.
Vitamin C for Normal Skin
Vitamin C for Oily/Combination Skin
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!).
