Hi doctor, I have been having a problem with my lips for the past few months. Earlier, my lips would only become dry and cracked during winters, but this time they have been getting very dry even in summer. Almost every day, the inner skin of my lips starts peeling, and sometimes my lips feel very dry and uncomfortable. I have tried plain Vaseline, but the peeling continued even while using it. I recently stopped using Vaseline, but now my lips  become very dry but peeling is not that much . I also make sure that I stay well hydrated. Could you please tell me what might be causing it and what I can safely use to help my lips heal?
