thanks for the photos. that looks like reactive skin or eczema.
cleaning chemicals, hot showers, dry skin can all worsen skin eczema
it could also be due to blocked skin pores.
I would use 1% hydrocortisone on the area twice a day for 1-2 weeks and make sure you moisturize after showers.
that should help.
if it doesn't, you may have to see a dermatologist for stronger steroid creams.
let me know if you have other questions.
