My son is 4-5 years past puberty, but he still has a lot of acne. Acne medication hasn't been effective. What causes hormonal acne, and can it be completely cured? (Vu Thuy, Dong Nai)
My daughter has had a lot of breakouts on her face and body since puberty. Many people say it's hormonal acne, not regular acne. What's the difference, and can it be treated? (Ngoc Trinh, Can Tho)
