Before you can apply your new lashes, there are a few more things you need to take care of. First, clean your hands, face, eyes and eyelashes. The eyes and the skin around them are extremely sensitive, so you'll want to make sure there's no soapy residue or anything extra that can get into your eyes. The adhesive may also have a hard time sticking to anything that has residual makeup on it.
Next, you should remove the eyelashes from the box with a pair of tweezers. They may vary in length, so you might need to trim them to have the desired effect. For a full, natural look, trim the extensions so they're closer to the length of your true lashes. For something more dramatic, keep them longer. You may also want to shape the lash over your finger to give it a natural curve and blend in more easily with your regular lashes.
