TONER! HELP!

So I'm 22 and honestly I've been experimenting with different products of all kinds (foundation, primer, eyeshadow, moisturizers, toner, blush, etc.) since I was about 15 and never figured out quite what works for me until this year. But toner is one thing I have not had any luck with. EVERY toner I've tried makes me break out!!! Any tips? My skin is fairly clear, a few breakouts here and there and mostly just little bump-type acne. But my skin tone is so uneven. Help!!
