I used retinol ointment over my enire cleavage and neck area for 3 days ( day and night) and came out in an itchy, red rash as a result. I didn't expose my skin to the sun at all. It was rainy, and I was covered up completely. Neck is clean but the whole cleavage, also breast are covered in red tiny spots. I stopped using the ointment, and resumed regular skin care routine. Is the rash going to disappear eventually?
