Sergand cordless Micro-needling Pen Professional kit. The kit comes with 20 replacement Blades ranging from nano, 16 pin, 36 pin, and 42 pin. It was extremely easy to use if you’re new to micro-needling. It didn’t hurt at all! My skin felt very soft and glowy with a minor amount of redness. I followed up with my favorite snail mucin serum and Epionce renewal moisturizer. LTKVideo LTKFindsUnder100 LTKBeauty
