Does It Matter If The Redness On My Hand From Using A Resistance Band Is Exposed To The Sun?

I exercise with resistance band. I perform the following exercise https://gethealthyu.com/exercise/resistance-band-squat/. The problem is that due to rubbing some part on my hand gets red. Afterward I go and run. Does it matter that the redness is exposed to the sun. Meanwhile i would like to mention that i go to the sun at 18:00 or afterwards.
