If you thought it was blistering skin, you are right!
These blisters are not caused by sun poisoning, those tend be more yellowish and follow extreme sunburn. This blistering happens a few days after you get a mild sunburn. The sunburn kills the tops layers of your skin and this "bubbling" of the skin is the first step in the peeling process. Moisture and heat become trapped under the dead layers of skin forming tiny bubbles on your skin.
These little blisters don't hurt though because they're filled with air, not liquid. They do, however, make your skin really itchy. Don't pick at your skin since this will expose the new skin before it is ready. Instead, moisturize your skin multiple times daily.
Fit's Tips: To speed up the shedding process and combat the itch, I like to gently exfoliate in the shower with moisturizing soap and bath gloves. Then when you get out of the shower, while your skin is still damp, moisturize, moisturize, moisturize!
