It is reported that Korean women is with flawless skin even in summer with Korean cream to apply to get their whiten & pink skin back after sunburn. Is it a falacy or not? 

The best advice is to avoid it in the first place whenever possible. Many people fail to realize that sunburn can occur even when the temperature is mild, and even on days that aren't particularly sunny. Overexposure can cause problems later in life, from wrinkles to serious skin conditions. Using sunscreen every time you go outdoors will help protect your skin from damaging UV rays.

If you do happen to get sunburned, there are various remedies you can use to soothe the pain and help heal your skin. Aloe Vera comes highly recommended, but be sure you purchase a product that lists aloe as one of the top ingredients. Always check the expiration date, since aloe is susceptible to losing its curative properties after time. In fact, the very best use of aloe is taking it straight from the Aloe Vera plant. Break open a leaf and remove the gel contained inside. Apply it to help soothe the burn, and to moisturize and protect the skin. 

Also, be sure to drink plenty of water, as the dangers of dehydration multiply with sunburn. It is not wise to drink alcoholic beverages, because they may increase the risk of becoming dehydrated. You may not feel like eating, but you should try to eat a little something to keep up your strength. Sunburn can be like any illness or injury depending on its severity, and your body needs nourishment to heal itself.

Taking a cool bath will also help make you more comfortable. The cool water will help lower your body temperature and reduce the heat of the skin. Soak in the water and rinse gently but do not use soap on burned areas. Soaps can remove naturally occurring oils that your body needs to heal. After bathing, dress in loose comfortable clothing and stay in out of the sun until your burn begins to heal. Be sure to get plenty of rest.

If your burn starts peeling, it may begin to itch as well. Try not to scratch, which can cause further damage. Apply calamine lotion to alleviate itching and use plenty of moisturizer to help re-hydrate the skin.

Never try to open blisters, as this may cause serious infection and scarring. In fact, if you suffer from blisters or swelling along with serious pain, fever, dizziness, or nausea, you need to consult with your health care provider. Sunburn can be very serious and may result in first-degree burns, which require professional treatment.
