I had the misfortune to suffer from acne when I was a teenager and thankfully it cleared up but I know that some people suffer from it for years into their adulthood. It can be embarrassing and makes people socially inept.
The doctor can help you by prescribing you with a number of treatments but these days many people are looking for more natural acne treatments and you will not find any more natural acne treatments than those found on acnexus.com
I am running the 2018 London Marathon to raise money for Livability UK in memory of my dad. If you can I'd appreciate any donation you can spare. http://uk.virginmoneygiving.com/deansaliba
