I guess you are referring to the leave it alone treatment.
Well if you are going to peel I don't recommend to peel it all at once because you might get eczema around your lips.
If you didn't peel for a while and suddenly do it you will traumatize your lips again and it can make your EC worse.
The body is constant adjusting to regularity so when you suddenly change your habits your body needs to adjust again.
One good treatment you can do while in school is having a healthy lifestyle. Don't change completely overnight because it's hard to make changes. Take it step by step and own it!
