Last night while applying fake tan I noticed the outside of my mole wouldn't tan which has left a white ring around it. I attended the dermatologist a few weeks ago regarding this mole as it was sore and with my anxiety I was constantly focusing on it and poking prodding it. The dermatologist had a look with her scope and said it didn't look interesting and was just irritated with my clothes rubbing. I'm now back to freaking out as I've read this is a halo nevus? And they can be concerning in adults, I'm 37. I suppose If I didn't apply fake tan I wouldn't have noticed. Has anyone experienced this that can calm me down
