Hi, Tetralysal contains Lymecycline , which is a broad spectrum antibiotic. It is used to treat bacterial infections of the skin such as severe acne. Yasmin is a progesterone and estrogen combination birth control pill. It is used to treat severe acne to counter androgenic effects, which helps to decrease the production of sebum. Hence, what treatment has been given is right and kindly continue to take the medications as advised. The duration of the response to the treatment could vary depending on the status of the underlying condition and the response to the treatment. Since stress also plays a role in improvement of the condition, kindly stop worrying about it and keep your mind healthy by doing meditation regularly. Along with it, you need keep the skin clean and healthy by washing with medicated soap thrice daily. You can also apply Clindamycin cream topically over the lesions regularly at bedtime. Gradually, you should be able to overcome the problem. Hope the information provided would be helpful. Let me know if I can assist you further. All the best. Regards, Dr. Ashakiran S
