The Dos and Don'ts of Mixing Skincare Ingredients

If you're new to skincare or have recently decided to add a few new products to your routine you make not know the do's and don'ts of mixing ingredients. Mixing skincare ingredients can either have a positive or negative effect on your skin, so it's important to be aware of what you're doing.

Here are a few dos and don'ts when mixing skincare ingredients:


Retinol is one of the most highly respected skincare ingredients that dermatologists love to recommend. Retinol is so great because it promotes skin cell turnover, which can help improve the appearance of wrinkles, fine lines, uneven skin texture, dark spots, and acne.

Do Mix: Retinol can be irritating so mix it with moisturizing ingredients like hyaluronic acid and ceramides as well as sunscreen!

Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids.

Vitamin C

Vitamin C is another highly respected skincare ingredient that is known for its antioxidant properties. Vitamin C can help brighten the skin, reduce the appearance of wrinkles and fine lines, and even help improve the appearance of dark spots.

Do Mix: Vitamin C with antioxidants and SPF. Sunscreen should be worn daily no matter what.

Don't Mix: Mixing Vitamin C with Retinol is a no-no!

Benzoyl Peroxide

Benzoyl peroxide is a popular acne treatment ingredient that helps kill bacteria on the skin.

Do Mix: Benzoyl Peroxide with other acne-fighting ingredients like salicylic acid and sulfur.

Don't Mix: Do not mix benzoyl peroxide with vitamin C or retinol. These ingredients can make benzoyl peroxide less effective.


AHA and BHA acids are popular ingredients for exfoliating the skin. They help remove dead skin cells and can improve the appearance of acne, dark spots, and wrinkles.

Do Mix: AHA/BHA acids with other exfoliating ingredients like enzymes and manual exfoliators.

Don't Mix: Do not mix AHA/BHA acids with benzoyl peroxide, retinol, or vitamin C. These ingredients can make AHA/BHA acids less effective.
