What treatment can I use in order to remove the fatty underarm bulge? (Photo)

I have two underarm bulges and I am not overweight. Even when I was 5 kilos lighter it does appear slightly smaller but won't go away. I have tried exercise. I didn't have this as a teenager but then when I was 16 I lost a lot of weight and when I regained it this bulge has been following me since I was 17. I am 25 no. I was looking into aqualyx or lipo dissolve as I would prefer liposuction as a last reserve only. Mainly due to its cost. I would appreciate any advice. Thank you
