Most parents who book a teen consultation with me have already tried a lot. Chemists' products, whatever the pharmacist suggested, maybe a cream from the GP that helped for a while and then stopped. By the time they get to me, they are not worried about spots. They are worried about scarring, and they are worried about a teenager who has stopped wanting to be in photographs.
Teenage acne is a medical condition, not a phase to be waited out, and not something your child caused by eating the wrong thing or not washing their face. It responds to proper treatment. The difficulty in Ireland is getting to someone who will look at it properly and stay with you while it clears.
That is what this is.
One thing I would say plainly: acne scarring is very difficult to reverse and much easier to prevent. The window for preventing it is while the acne is still active. That is the reason not to wait this one out.
