On clean skin, apply a few drops of your favorite serum to the area to be covered. Be careful just to use a small amount of product.
Gently pull skin flat in desired area & apply mask. Add light pressure with your fingers to press it into place. Wait for desired amount of time.
Remove mask & immediately wash the silicone with light soap & water. For best results, let air dry print side down (sticky side up). Return to its tin for storage.
