Microneedling at home. No way. Home use needles, get products into skin. Don't go above 0.1mm please. It's needs to be sterile, sterilized. Don't want infection, flare up of cold sores etc. in combination with the fact that people needle stuff into their skins that often isn't designed to be needled into the face in the first place!
I have nothing against collagen boosters , skinade drinks, smoothies, carrots, multivitamins. All the things you didn't have the time to make. Make them now.
