This product is a spot treatment intended to dry whiteheads, and so it does. I did notice it helped in drying out the pimples once the white head is out, however, after using it for a while I have to say it is nothing miraculous. It would take 2 nights of using this product in order to see the blemish dry out. In my opinion, that just like saving 1 day of having the pimple "fresh". I do appreciate it, but I wouldn't miss this product in my routine. I feel you could get almost the same results with a simple diy alcohol or vinegar dilution.
The tap has an applicator attached, like a nail polish. I do like it since I have seen that similar products don't have an applicator and you have to use cotton swab every time. Since the formula is mainly alcohol and antibacterial actives I don't think the applicator gets contaminated, but that just my opinion.
I would recommend this product if you are looking for a drying solution and prefer natural ingredients. It is also more affordable than similar products. I bought mine in Iherb. Please note it does nothing about blackheads or cystic acne.
