Review on 💫 The INKEY List Niacinamide 30ml: Ultimate Skin Enhancer at Your Fingertips! by Patty Martin

I've only been using this product for a few weeks. Here's what I know. Apply to damp or slightly damp skin after cleansing. Do not combine with vitamin C serum. These are contraindications. Feel free to apply hyaluronic acid and retinol! I find it best to use even if I can layer. Tightens pores and makes skin clearer. I'm a beautician. I planned on rubbing the products all over my face until I put a few drops in my palm. You can mix several products and rub them into your skin instead of rubbing it in. Try it and see what you think.
