The Hydrocolloid Pimple Patch and Microdart Spot Patch each have two one-week use studies and a separate 24-hour primary skin irritation patch test. The two one-week Microdart Spot Patch studies evaluated the complete Blemish Clearing Pad and patch routine. The 24-hour tests evaluated each patch separately. These six studies do not apply to the Microdart Acne Patch.

The two one-week Microdart Spot Patch studies evaluated the complete routine: Blemish Clearing Pad followed by Microdart Spot Patch. The separate 24-hour primary skin irritation patch tests excluded people with sensitive or hypersensitive skin. These short-term results do not mean non-irritating, hypoallergenic, or suitable for every skin type. The Hydrocolloid Pimple Patch and Microdart Spot Patch are cosmetic products; neither is intended to treat, prevent, or cure acne or any other medical condition.
