Firstly the packaging has changed, so if you want to buy it, it no longer looks like this. I'm not sure if i like the new packaging though.
What it says:
• extra-strength with pore-refining salicylic and lactic acids• begins working immediately on application
• with irritation soothers and redness reducers
• slows down oil-secretion
• strategically formulated for oily and combination skin
This truly works. It works from the first application, drying out the spot and reducing redness within hours. After about a day you will notice that the spot is getting smaller and after a few days it will be almost gone if not gone completely. You can even use it under makeup as it creates a invisible barrier between it and the makeup. You only need a small amount for one spot so it lasts quite some time even though it's only a small tube.
I can't say if it drys the skin or not as i have dry skin to start with.
I'd say this is for the random breakout spots you may get and not to treat acne though.
Would i buy it again? Yes when i run out as it really does work. I use this every time i get a breakout.
Sorry i can't link to boots the site isn't working for me, but here it is from the Soap & Glory site.
