how long does it take for doxycycline to work for acne

Doxycycline typically begins to show noticeable improvement in acne within 2 to 4 weeks. However, it can take up to 8 to 12 weeks (around 2 to 3 months) for the full effects of doxycycline treatment to be visible. The usual course of treatment for acne with doxycycline lasts between 3 to 6 months, depending on the severity of the acne and individual response to the medication. Consistent use as prescribed and completion of the entire course are important for optimal results and to avoid recurrence or antibiotic resistance.
