Vitamin C + AHA
Be a bit carefulBe a bit careful. Layering low-pH vitamin C with an AHA can sting, especially on sensitive skin - it's a lot of acid at once, not a catastrophe.
The classic fix: vitamin C in the morning under SPF, and keep the acid for the evening. You get the brightening and the exfoliation without the double-acid session.
If your skin is hardy and both products are well formulated, some people do layer them - but if you're sensitive, rosacea-prone, or new to acids, split them and patch-test.
