How to start Iodone

Hello to everyone.

I am very overwhelmed with the mass of info on here and I hope it's not too uncommon to ask how to start.

I bought the 5% Lugols' because I read that's the one I wanted if I were to use it topically. I am planning on using it internally but also wanted to treat a cyst I have on my face topically.

My symptoms I am hoping to address are, acne, cystic acne, being cold; cold fingers and toes, digestion issues, tiredness, Depression (mostly the really bad times are related to social anxiety because of my skin) and most recently hair thinning out.

I have been taking vitamin C and have already starting doing 1 to 1.5 teaspoons a day of celtic Sea Salt to help with digestion and overall health.

I am not home at the moment but expect to be in about a week and I have selenium at home and will start taking that then.

So my questions are how much to take to start ( I know the recommend amount by Dr Brownstein is 12-50mg) and also is it a big deal if I don't have the selenium the first week?

I don't want detox symtoms but I'd rather get it over with quicker if I am to go through it.
Also would like to know have any of you NOT gotten detox symptoms? And does the salt protocal always properly take care of it?

Thank you so much to anyone and everyone's help. I am desperate to not feel like I always have to worry so much about my skin and what I eat and really appreciate your help!
God Bless
