Hi,
As you said you suffer from
acne vulgaris. And you took antibiotic without response.You may be knowing that acne is a recurring skin disease and caused by multiple factors. Genetic influence may be also there.
Stress,anxiety,sun exposure,oily skin,oily food, dandruff,
sleeplessness,drugs like steroids,pills,iodine..etc factors might exacerbate the disease.
You should continue treatment for long time even after control of disease.
Antibiotics like
minocycline or azithromycine in proper doses and
isotretinoin in low dose may be taken under observation of
dermatologist. Local application of clindamycine with adapalene gel at night with cleansing the face by antiseptic face wash like cetaphil may be considered.
Avoid to squeez or to rupture the acne lesions,otherwise your lesions may be infected by bacteria. Then you have to take antibiotic like cephalaxin and to apply antibiotic cream like sisomycine.
Avoid anxiety related to acne.Keep patience for the good result.I hope you got my answer.
