Double eyelids are done under local anesthesia, so there will be no pain when doing it, but after all, it is surgery, and there will be some swelling after doing it. Generally, it will recover naturally in 5-7 days, and the superficial wound seems to have healed. It takes 1-3 months to fully recover from internal injuries, which is a recovery time for human body and skin to be invaded by the outside world. The double eyelid itself is built on the basis of beauty, so as long as you choose a trustworthy hospital, it will be more secure and will not leave scars. O(∩_∩)O~

I won't recommend you to go to the hospital because it's not where you come from (lest others say I'm procrastinating, hehe), but you can do it with confidence (because double eyelids are a minor operation) O(∩_∩)O~
