@kiyokobeauty: Not all skincare ingredients play well together 👀 Mixing the wrong actives can lead to irritation, dryness, and breakouts—even when the ingredients themselves are great. ✨ In this reel: ✔️ Vitamin C + Niacinamide = yes ✔️ Retinol + Niacinamide = yes ✔️ Hyaluronic Acid + everything = yes ⚠️ Vitamin C + Retinol = use separately ⚠️ Retinol + BHA = alternate nights Sometimes it's not that your skincare isn't working—it's that you're layering it wrong. Save this for your next skincare routine check, and send it to a friend who's mixing all the actives 💌 #kbeauty #serum #serumviral #retinol
