hi thanks for choosing hcm yes minocycline an antibiotic fluconazole an antifungal isotretinoin a retinoid and the gel good combination therapy indeed,are all these prescribed by a doctor...then you have too much of acne right but if you have sensitive skin,and if you go to the sun after using the gel,it makes your skin worse take measures like: 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 reduce your medication frequent facewash peeled off skin exposes young sensitive layer of your skin,which is more sensitive and gets pigmented very quickly when exposed to sunlight so better to stop using the gel go and meet you doctor ask him to change the medication dont worry pigmentation,dark skin can be treated by medication,but only afterr you completely get rid of your acne so be cool,talk to your doctor and take help accordingly feel free to cotact me for further queries thank you
