It depends on the products, I suppose. 🙂 For example, vitamin C absorbs better in a lower pH environment, so it's better to use an exfoliator first. But if the exfoliating ingredient is in moisturizer or a thick serum, it's better to apply the vitamin C first.

That depends on the formula of vitamin C. Some have pH even above 5, but the best for absorption is a pH of below 4. If your vitamin C product has higher pH, it could be beneficial to use an acid before vitamin C application.
