I always seem to have 3 or 4 blemishes, oh ok then blardy great whiteheads and a couple of blackheads. When I get rid of them they go to a faint red mark for aaaages.
I moisturise daily, wash face thouroughly, use a face scrub, drink water, use spot treatment, all never work.
I'm sure it's hormonal as with each pregnancy I have had beautiful skin. I am tempted to go on the pill purely for that reason.
