@ashley_breaks_beauty: Niacinamide is one of my favorite skincare ingredients…but I’m seeing a lot of people accidentally overdo it. What people think: “If one product has niacinamide, five must be better.” What’s actually true: Stacking multiple high-percentage niacinamide formulas can overwhelm the skin barrier and cause redness, sensitivity, or breakouts…especially if you’re also using exfoliating acids or retinoids. Who it’s great for: Oily, acne-prone, uneven texture…when used thoughtfully. My rule of thumb: One niacinamide product at a time is usually enough. #niacinamide #skincareroutine #skincaretips #BeautyTok #skincaretips
