Hi it depends what you mean by cheap!? Also, is your acne active at the moment? If you are currently suffering with breakouts, it's better to wait until your skin is calmer before you try any treatments.
At Waters Edge Clinic we specialise in skin treatments and problems. We offer a peeling treatment that helps to de-congest and clear the skin, and also helps to tackle scarring and redness.
The cost of this treatment is £45.
Hope this helps, and if you want to contact the clinic for a chat about your skin, we'd be happy to help.
