Doxycycline and sun

Patient: I am currently taking 100mg of doxycycline one to two times a day, and have been on it for several months. However, I am planning on going to Florida in a few weeks and am wondering how much of a risk it is in getting a lot of sun exposure. The medication is helping to clear my skin and I have tried going off of it in the past and my skin got much worse so I am hesitant to go off again. I am wondering what your recommendations are. Thank you so much for your time!
