Dry Mouth Corners
A few weeks ago, I noticed I had dark spots at the corners of my mouth. One on each side. Both are dry, and make my skin a darker shade. One day my skin there was normal, the next it was darker. I noticed this after a New Year's party and previously I had switched to a new face wash. I have switched back to my old one and have been applying plenty of moisturizer to the spots to prevent flakiness and drying out.
The spots tend to flake throughout the day even though I exfoliate every other day and moisturize often. They are also rough at times and feel different to the rest of my skin.
I haven't been able to find out what it is or how to get rid of it through searches and I'm really hoping I can find some help me. The spots go from the corner of the mouth and a bit down. They aren't too big but they make me look like I'm frowning constantly. Any idea on how to fix this?
