Thank you for your question.Minocycline can make your skin more sensitive to light; including sunlight, tanning beds and even lasers. You have a higher chance of developing a burn if laser treatments are performed while on this medication. I would inform the provider who is performing for hair...
The person who performed your treatment should have a medical Director or a physician who is knowledgeable about laser assisted hair removal who ultimately has responsibility for the patients treated at the clinic, I recommend being examined by the physician overseeing your treatments.
Best approach is to have the procedure done in a dermstologist's office. Results , & side effects depend on the machine type & the doctor's experience. Settings on the machine vary according to the skin color & hair color/thickness. A novice technician can definitely cause harm.
