The gel is to be applied to any blemishes that refuse to leave. It's inparticularly good for the massive under the skin spots that never seem to come to a head. Put this on over night and the pain will instantly disappear, as will the spot, if not coming to a head.
It contains the mighty salicylic acid that stings a little when applied to open blemishes, but it's worth the tiny sting for the after effect. I'm personally of the opinion that if it stings, you know it's working.
It is dispensed by squeezing the product out of the small hole, meaning you can greatly control the amount you need. This, by the way, is the tiniest amount. You need literally the size of the spot amount to cover it. Leave on overnight and then you can usually just peel off the set gel in the morning, if not then a quick face wash will rid it.
It's definitely a repurchase item for me, and while you might not wake up blemish free every single time, it will certainly speed up the process.
