Hi,
Adult acne affects 5% of males and about 10% of females. In female adult acne, hormonal factors may be responsible. Treatment strategies are similar to that for adolescent acne.
Mild acne being treated with topicals. Moderate acne will require additional oral medication such as oral antibiotics, isotretinoin and hormonal therapy in females. A full course of oral isotretinoin over 9-12 months often gives long-lasting benefits for more severe or persistent adult acne.
A thorough assessment by your doctor will help determine your suitability for the various treatment modalities.
Hope this helps!
