How to avoid "rebound effect" on acne post summer?

Marion

Hi everyone ! So I have kind of an acne prone skin, I mean I had some acne for a couple of years but I seems to really calm down since a couple of months (about 5 months), I get a few pimples every now and then, when I'm on my periods too, but it's really not that bad and I'm si glad about it, it makes me feel so much more confident ! I have a couple of acne marks on my face but you can't really tell because i have freckles so it kinda "melts" the acne marks, so now we're in summer time and I'm afraid that when summer will be over, and my skin won't get sun on it anymore, to have a rebound effect on my skin, I mean to have so much more pimples, so I was wondering how to avoid that?

I have a pretty simple skincare routine: Every morning I spray the Mario badescu rose water spray on my face because I like the little hydration and glow it gives to the skin, and every night after my shower I apply an aloe Vera hydrating cream. When I have a pimple I apply tee tree oil on it. And also, when I'm going to spend a day or even only a few hours at the beach I put some spf 50 sunscreen on my face. Will this avoid the rebound effect ? If you guys have any advice or recommendations I would love it !
