For some reason my arms and chest look almost sun burnt to various degrees of " brightness" but always there and u can see my finger print if I touched it.
Have noticed something similar with dd2s legs although not red but more ever so slightly mottled just like when she was a baby 🤔not for very long and not every day but again u can poke it and see your finger mark.
Its all a bit odd. No other symptoms at any point ever.
Mystery allergy maybe?
