Im 13 and i want clearer skin?

Well some things you can try and change and some can not. Double chin is very hard to get rid of and you are young yet so time will tell, but try lose some weight and see if helps. For the redness etc you may have rosacea in which it seems is your symptoms. You can google it and learn a lot about it or you can see if parents will take you to a dermatologist they can prescribe oral and also creams. Your freckles are just there freckles are cute Again the chubby cheeks and chin may go away losing some weight
