A lot of us have been there, but sometimes it's good to take a breather from thinking. Also please note that reviews are very subjective especially if you're reading ones on sites like purse forum there is a lot of disinformation on there and that's why we made beauty hacker to make a better research community. But here are some cautions about researching:
Researching Plastic Surgery (PS) too much can:
Make you a perfectionist and develop unrealistic expectations
Consume your thoughts and distract you from other things in life
Create a paradox of choice and analysis paralysis by knowing too many options
I recommend to create some clear goals, understand the risks, hope for an improvement, but have some flexibility that it won't be exactly like how you imagined. Try to see if you can do it in your home country first, or use that opportunity to learn more about treatments before going to Korea.
