I'm out in the sun a lot in the summer and I've developed some discoloration on my lips.
To be honest, I use lip balm but not usually with SPF and that must be the reason.
It's been a few months since I was out in the sun but the discoloration is still there. I keep wearing dark colored lipsticks to hide it. I'm going to be more careful about wearing lip balm with SPF from now on but I don't know what I can do to treat the discoloration that is already there.
