when a pimple patch doesn't have the micro darts of other ingredients in it to actually treat the acne, the reason I recommend it is based on stickiness and disappearing (if its meant to be invisible). These ones are sticky enough they don't move throughout the day but the do sometimes come off in the night. They are super invisible because I've washed my face more than once in the morning, did my entire skincare routine, only to look in the mirror a few Horus later and still see one stuck on my face. I only gave it a 4 because again a few fell off at night and I have others that never do that.
