If a drug is photosensitive enough to impact LHR, stopping for 1 day won’t be enough. I would talk to your clinic and your doctor. If Chris thinks it’s ok, he might have previous experience with this specific drug.
p.s. Danika, unfortunately for the industry, I know quite a bit more than many laser techs treating people who come seeking advice on this forum. I’ve been studying the industry for 10 years now, and have gotten great results from both laser and electrolysis due to this (something I don’t believe you can say yet, but hopefully you’ll learn enough to stick around and help people here. I don’t disperse medical advice here - and neither should most laser techs as the majority don’t have any medical degrees and just took some hours of training with whatever company sold them the machine).
