First, never use a cotton-tipped applicator.  Cotton fibers will stick to the ointment.  If you prefer not to use your finger, choose a firm applicator; a wooden paddle or spoon handle is fine.  If Perrin’s Blend is sticking to the applicator you may want to slightly oil the applicator before applying.  If you are covering the area with a bandage you can apply the Perrin's Blend directly to the bandage and then apply the bandage to the skin.
