Hello, everyone. Sorry for creating new thread, i just couldnt find my old one. Last time i wrote only few sentences about my problem, becouse i was rushing. This time ill try to explain all details.
I have acne since 14-15yo old. At teen years till 20years old it was just teenager pimples becouse of puberty. But now, its something else. Bacteria, allergy, i have no idea. I have less white heads, and i have less pimples generaly than i had in my teen years, but when i get new pimple, it form like 1-3 weeks in one big,red, painfull. Last acne spot was VERY big and very painful, it was like 4cm wide. But it gone before it poped lol. I read on some forums that best solution for such acnes is to ice it before it formed white head, so that's what i do. It was already 4 such pimples, now i have 5th on my cheek. This one is much smaller, but not less painful. It also hurt, when i wash my face (i dont touch my face with hands).
 About my diet. I dont use sugar (i only get suger from food wich is impossible to avoid). I dont  use salt. I almost dont eat cookies, candys and chocolate (like 5 candys per month, its not a big deal.... i guess). 
  About dairies, i think thats biggest allergen for my acne,  i noticed when i eat careals with about 400ml of milk, after few hours my red spot becomes much more painful and after ~12hours it's much bigger. Im not sure if its becouse of dairies, becouse i noticed it only 1 time yet. But still i almost cut dairies out of my diet. I use vitamins C and fish oils daily, drink a lot of water, green teas (2-4liters per day, depends how hot the day is ).
  Without those pimples i have a lot of scars little  red spots few milimeters wide. Also my face skin is really sensitive, it get's red above my lips when i wash my face, or put mousturizing  crem on (my skin around my mouth is very dry). 
  When i wash my face, i barely touch my face with my hands, becouse i dont want to iritate skin. I remember when i was young i had very nasty habit to touch my face with my hands, when i was sitting in class, i was always hodling my face with my palm while sitting, but i dont do it anymore for last few years.
Anyway, anyone have same  problem? how do you solve it? have you tried icing it (put ice and pimple and hold it for few minutes, then stop few mins, hold again, stop, hold, stop, and cont for ~40mins)? How to solve problem with redness? What to do with little red scars? Thanks god these scars are not deep scars, so i can cure it and make it much less visible, maybe even fade it at all. But still major problem right now is with these big red painfull pimples.
