Quick-drying gel that doesn't smell too overpowering, and is said to reduce spots within eight hours. Pleasantly cooling on skin and doesn't over-dry area around spot - although I couldn't detect a visible improvement 10 hours later.

State-of-the-art zapper that's meant to heat up to just the right temperature to destroy bacteria without damaging outer skin. Reassuringly hot; feels as though it means business and reduced the itchiness from one small spot.

I suspect this could remove nail varnish and strip paint, too. It's a cult product that has built up a loyal following of zit-free fans. I can see why - it's extremely effective.

from Boots nationwide

Pure scorched-earth policy for spots with its antiseptic and antifungal properties, powerful camphorous odour and strong, tingling effect on skin. Rapidly dries out the most offensive of pustules - my favourite remedy by far.

A mild and gentle gel with witch hazel that doesn't feel as if it quite has the hitting power of some of the others here. But it is soothing and good at reducing redness - also free from parabens and petrochemicals.

One of Hollywood's secret weapons for that perfect celluloid complexion, this powerful yellow potion is particularly good for taking redness out of a spot - especially if you've committed the cardinal crime of squeezing it first.
