If you’re prone to skin redness, itchiness, and dryness after your morning or evening skincare regimen, don’t blame the products themselves. Instead, blame your regimen.

It turns out that certain products should not be put on in conjunction with one another. Doing so may just be why you have these uncomfortable symptoms. Here’s which skincare products you should not mix together.

Vitamin C and Beta or Alpha Hydroxy Acids

In certain instances, these two skincare products may not bother the skin due to their similar acidities. That said, it’s a good idea to put on just the beta or alpha hydroxy acid, see how the skin reacts to that, and then slather on the vitamin C cream as necessary. If skin redness or drying occurs, do not mix the two again.

Vitamin C and Benzoyl Peroxide

Vitamin C does not play nicely with benzoyl peroxide. Why? It turns out benzoyl peroxide may erase vitamin C’s skin effects, which hurts your wallet. In some instances, vitamin C and benzoyl peroxide toner may get along better together, but not always.

Retinol and Benzoyl Peroxide

If benzoyl peroxide is part of your daily skincare routine, you must be careful with retinols. If the two products are put on together, neither product works. What if you need both retinols and benzoyl peroxide, though? You’ll have to put on the benzoyl peroxide at one time, such as earlier in the day, and then the retinol before you go the bed.

Retinol and Beta or Alpha Hydroxy Acids

The salicylic acid in beta hydroxy acid as well as the citric, lactic, and glycolic acid in alpha hydroxy acids are fine for most skin types on their own. When placed over a retinol, which lessens the appearance of wrinkles, fine lines, brown spots, and even acne, the skin may become agitated and reddened. Not only that, but you may dry your face out.

Retinol and Vitamin C

Vitamin C is a great product for turning back the hands of time by subtly erasing fine lines and dark spots while restoring collagen. You already know what retinols do by now. The two have similar functions yet require two separate pH balances, such as 5.5 or 6.0 for retinol and 3.5 or lower for vitamin C. Blending the two may lead to a reddened visage.
