The Banisher Roller is for most kinds of scarring including acne scars, dark spots, hyperpigmentation, boxcar scars, rolling scars, ice pick scars, and stretch marks.
The Banisher Stamp does the same thing as the roller version. It's equally as effective too! Stamp the area instead of rolling with the pen. It's smaller so you can use it on areas like the nose and temples easier and it makes it easier for you to stamp around an active pimple.
Don't use over active acne.
