Thank you for your question. My name is***** - I am a Dermatologist and will do my best to provide a useful input.

Would a photograph of the affected area be possible at your convenience?

Customer: replied 10 months ago.
Hopefully these photos work
Expert:  Dr. Nair replied 10 months ago.

Thank you for the photographs - are these on top of the arm or the under-surface?

Have you had more sun exposure than normal in the last few days?

When did you notice this patch?

Customer: replied 10 months ago.
They are in the underside of the arm
Only noticed it Sunday but Thursday, Friday and Saturday were quite sunny!
I've also been using plain soap of late also

Thank you for the information. The rash looks quite non-specific. It could be a mild heat rash or it could be a reaction UV rays (this is a rash called PMLE). Either way nothing to worry about.

I would suggest just keeping the skin moisturised with a bland moisturiser like Cetaphil and the rash should clear up in 1-2 weeks. If you don't see much improvement in 2-3 days then you can apply Cortizone-10 ointment (available over the counter without a prescription) twice a day on the patch for 7 days or so and that should do the trick. In the mean time stay out of direct sunlight as much as possible and avoid extremes of heat or humidity. Use a soap free body wash for bathing.

I'd be happy to answer any further queries you may have. If not kindly consider rating our interaction positively to enable me to get credit for my work with you. You can continue to follow up even after if required. Thank you.

definitely one of those two? just wanted to add a better photo

Hello again,

Yes those two look most likely. Could also be an allergic reaction to something else that came into contact with the area but that's about it. Management would remain the same.

Let me know if you have any more queries, I'd be happy to answer them.
