This was one of the products I also received in my hamper. Its awesome suff with a rich menthol smell. I applied some last night on a pimple I had and it went to work instantly. Felt a bit on a tingle on my skin but that was shortlived.
Really helps to get rid of spots quickly, and the roll-on is a great advantage - because you don't apply it with your finger, there's no bacteria transfer to your face (a very good tip for avoiding spots!)
Wwarning: the packaging does indicate that use of this product will make your skin sensitive to the sun so be sure to wear a borad based sunblock at least spf 15.
Garnier Pure Active Spot Roll-On is a good treatment; I have tried a lot of treatments and this is definitely one of the best. A good point about this is that it also helps to fade marks, which is problem that others don't address or make slightly worse..

some points of interest:

roll-on, so increases face hygiene
- maximum concentration of salyic acid - dries up the spots in no time
- definitely reduces swelling, and dramatically increases healing time
- packaging has lots of info on the product and ingredients
- products lasts a long time, so it makes the price worth while
