Official answer


Absorica starts to work within 4 weeks but may take up to 20 weeks (5 months) for the full effects to be seen. Within four weeks of taking Absorica, a more than 33% reduction in the overall number of acne lesions was reported. Over 70% of people with severe nodular acne achieved a 90% reduction in the number of their nodular acne lesions after 20 weeks with Absorica. A single course of Absorica for 20 weeks has been shown to result in complete and prolonged remission of acne in many patients.
