In my exploration of skincare, I came across a common ingredient called Benzoyl Peroxide. It's often used in acne treatments, but if you're dealing with rosacea, you might want to steer clear. I've found that it can potentially exacerbate redness and irritation, which are symptoms those with rosacea already struggle with. So, despite its effectiveness against acne, it might not be the best choice for everyone. Keep this in mind next time you're in the skincare aisle!
