It's been a problem for me since the age of 13 and still twenty years on, I'm cursed with blemish prone skin. It's linked to hormones, the fact both my parents suffered from acne and my sensitive combination skin which reacts to a lot of products. It also takes a lifetime to heal.
I have to say that now I'm a lot more comfortable in my skin generally in terms of looks, weight etc. and have learned to accept my acne (as unattractive as it is). However I still can't bear the thought of leaving the house make up free. To me that's my worst nightmare!
Over the years I've tried changes in my diet, antibiotics and various potions that chemists, GP's and alternative practitioners have given me (some of which have been pretty scary and taken layers of skin off) to no avail. The one thing that did work very well was Dianette contraceptive pill but I couldn't stay on that forever and when i came off it, my skin really flared up. It's very hard at this age trying to find products that tackle the blemishes while moisturising ageing skin...
I have found some products I really like however and do seem to make a bit of a difference although they are not a particularly preventive measure.
The Freederm range seems to be pretty effective at reducing redness and inflammation and I have just started using the overnight serum which is promising. Korres are a Greek company that I have dipped in and out of over the years. They are a little expensive though. Korres had a store in Edinburgh which unfortunately closed over the last few years so I buy online now and Liz Earle's products are a cut above but due to frugal times, I can't always afford to shop there. Always a good product to have on your birthday and Christmas list though!
