Why does sunburn cause peeling? It is a normal phenomenon of dead cells peeling off

The weather is quite hot in summer. If you don't take good sun protection measures at this time, you will easily get sunburned. Sunburn means that the skin will become red and swollen in patches, and in severe cases, it may even cause peeling. So, why does sunburn cause skin peeling?

Why does sunburn cause peeling?

Sunburn and peeling are caused by the skin being exposed to the strong sunlight outside, and the skin usually does not peel immediately, generally one to two days after being exposed to strong sunlight. So for us, if we get too much sun, our skin will peel off, which is a normal phenomenon. Peeling caused by sunburn is because dead skin cells need to be sloughed off to make way for new skin to grow underneath. Although it may not look pretty, it is an important part of the healing process.

Tips: Dead cells always need to be sloughed off, so it is better to let them complete the whole process naturally rather than intervene manually. For example, it is best to let them fall off naturally rather than tear off the dandruff with your hands.

How skin gets sunburned

Overexposure to the sun can severely damage the outer layer of the skin, killing skin cells and causing redness, swelling and blisters. Normally, during the first few days after a sunburn, the dead skin remains intact while the body builds new cells underneath, using the dead skin as a protective layer because the new skin is still delicate. Just as new skin cells are getting ready to take on the world, that’s when the damaged skin above is shedding moisture. Dry skin begins to flake and peel, eventually revealing new cells underneath. During this process, these new cells are fragile because they have not been exposed to sunlight before.

What to do after sunburn

The first thing to do is to use a cold towel to repair it, because cold compress can lower the temperature of the skin and relieve the redness and swelling caused by sunburn. You can also take a shower, but be gentle and don't scrub too hard. After showering, dry yourself with a soft towel. Then use sunburn medicine for treatment. Never scratch the sunburned area with your hands, as this will be bad for your own condition. Use after-sun repair cream. If your skin is sunburned, you might as well apply some after-sun repair cream. It is good for skin pain and can also improve the skin.

How to avoid sunburn and peeling

The best way to avoid peeling is to use sun protection and avoid sunburn. Prevention also helps keep your skin in tip-top shape and slows down the aging process. Additionally, for those who have already suffered a sunburn, proper care can help mitigate the peeling process. Wash with mild soap and cool water and pat dry with a towel rather than rubbing. Some people find that applying some vinegar after a bath can effectively reduce the itching associated with sunburn and reduce peeling. Additionally, moisturizer can help hydrate damaged skin and prevent excessive peeling.
