HI, THANKS FOR CHOOSING HCM, severe acne problem may be due to reasons like hormonal imbalances polycystic ovaries(though your periods are regular pcos may be present) exposure to dust and pollution infections so meet your doctor rule out the cause first some good tips: completely clear out your dandruff take less fatty foods, go for good diet and exercise keep your skin away from pollution(use a scarf etc) try to control cause of acne frequent facewash as well as hand wash stop fast foods seriously have fresh fruits,green leafyveggies ,fruit juices reduce spicy foods dont scrub the area inorder to get rid of pimples because it makes your pimples spread dont squeeze them ,it leaves pores and dark patches clear your pimples by following the above measures or meet a doctor... once your pimples get cleared completely then only treatment of pores and black patches can be cleared succesfully . this happens naturally after your pimples clear off or you may need medication also(ointments like melacare helps in clearing marks but this should be used after complete eradication of pimples) remember dont go for facials when you have pimples it worsens the condition natural remedies like neem leaf paste and tulsi paste application can help you with quick results but when you apply anything on face check that it suits you and only when you are sure it is working go ahead with it and also remember that when few creams are used initially acne gets worse but later it works very well so it is up to you to judge whether to continue or stop it hope i answered your query feel free to contact me for further queries thank you
