Dr Susannah Hoey, Consultant Dermatologist at the Royal Victoria Hospital, gives advice on acne treatments.
Most of us, at some stage of our lives, will get the odd spot. But for others it can be more problematic.
In fact, for those who suffer from acne it can mean years of feeling self-conscious or inferior.
This week on Health Focus, our Health Correspondent Marie-Louise Connolly talks to Dr Susannah Hoey, a Consultant Dermatologist at the Royal Victoria Hospital in Belfast who gives advice on dealing with skin problems.
We also find out how young people cope with acne.
The most common cause of acne is hormonal changes. From puberty, the body starts to produce sexual hormones, known as androgen.
These changes cause most adolescents, both male and female, to experience some form of acne, ranging from very mild to moderate.
However, in some cases the acne can be quite severe, resulting in permanent scaring of the skin.
Acne problems disappear for most people when they reach adulthood and hormone levels begin to regulate again.
For others, they have acne into adulthood but for a small minority, it never goes away.
