Come and ask on Style and Beauty!
Basically most people can do it with:
Non-foaming cleanser such as Cetaphil, La Roche Posay Physiological Cleansing Gel, Avene Extremely Gentle Cleanser
Salicylic acid product such as LRP Effaclar Duo, Paula's Choice 2% BHA (there are loads of others but these have a higher % of salicylic + the right pH)
Oil-free moisturiser e.g. Cerave PM, Cetaphil moisturiser
In the mornings oil-free SPF, possibly instead of the moisturiser eg Sunsense Daily Face
Go back to basics with your routine - start with just cleasner and moisturiser and introduce one other product every 3-4 weeks, don't be phased if initially you come out in new spots.
If that hasn't worked add in LRP Redermic R
And then if that's not worked see your GP, you need a prescription.
