Acne treatment depends on stage of acne and there are many reasons for not getting good results like improper dosage, irregular treatment, underlying infection which is not addressed.
With proper treatment plan you should see good results and clear face within 3-6 months. We have to first start with few blood tests and then start with antibiotics first to clear infection. After that we switch on to isotretinoin if required in proper dosage as per your body weight. Chemical peels if done properly works wonders and clears acne within one or two months. Once we have cleared active acne, next stage is treatment of acne spots and scars which again requires different creams and procedures like Laser, Dermaroller, etc.
Next Steps
I would suggest you share all details of your treatment and blood tests if you have done and the pictures showing affected areas. Once I check everything il write a complete treatment plan that you have to follow regularly and you will definitely see good results.
