This happens to a lot of people with acne. Pimples keep coming back when medicines are stopped because acne usually needs long-term, regular treatment, not short courses.
It can be related to hormones, skin type, stress, or wrong products being used on the face.
Next Steps
You need a proper skin routine and medicines tailored for you, used consistently for a few months.
Best to consult a doctor so treatment can be adjusted instead of changing medicines on your own.
Health Tips
Avoid creams or home remedies without advice, don’t squeeze pimples, and avoid heavy/oily products. Acne improves slowly, not overnight.
