Using these peel and stick prosthetics is a breeze. First, peel the prosthetic from its backing. Then, stick it firmly on the desired area of your skin. If you notice any edges, grab a little acetone and gently apply it to melt those edges away for a perfect finish. After that, blend the prosthetic with your skin and apply the color you want. Remember, you don't need any extra adhesives. When it comes to removal, use a gentle makeup remover to take off the prosthetic without harming your skin. To keep these prosthetics in good shape, store them in a cool, dry place away from direct sunlight. Avoid bending or folding them too much when not in use, as this can damage the material.
