Mixing skincare ingredients incorrectly can make them ineffective and ultimately a waste of money, or even worse, causing skin irritation and dryness. Find out the ingredient combinations you should never put on your face in this article.
Vitamin C + Retinol
Layering these two powerful ingredients one after the other could cause irritation. Not only because of that, but also the effectiveness of the products can become compromised if combining the two ingredients together. Still want to use both of them? The best way is to use vitamin C serum in the morning as it functions best in the daytime and retinol cream at night to stimulates collagen production and cell turnover.
Benzoyl Peroxide + Retinol
Have been dealing with pimples for a while? Then you should be familiar with these two acne-fighting ingredients. Remember not to layer the two on top of each other as benzoyl peroxide may inactivate topical retinol. If you’re worried, use benzoyl peroxide in the daytime and apply a retinoid at night.
Retinol + AHAs/BHAs
Combining these ingredients together can cause excessive skin sensitivity, irritation, and redness. Never mix one and other on top of each other. If you still want to use retinol with the above, apply it in the morning and use the rest at night.
