Inflammation of the hair follicles and oil glands causes acne. In teenagers, acne may be due to increased androgen hormones acting with hereditary factors. Other factors contributing to acne are emotional stress, touching your face often, oil-based cosmetics, drugs with lithium or steroids or a dysfunction of the ovary or adrenal glands. Acne strikes at male teenagers or menstruating females. There is no cure for acne.
Treatment can only improve the condition of acne.
Usually, acne can be controlled with washes and gels which are commercially available. Some people will seek medical treatment for even the slightest show of acne. Others may not be overly concerned with it. Acne cannot be prevented. It is a hereditary disposition.
