Personally, I recommend that you do NOT pursue either laser or IPL. You stated that you have tan skin and thin hairs. This makes you a poor candidate and more likely than not if you do more treatments you will just end up with laser/IPL-induced hair growth.
Fortunately, you've only done one patch test. Since it's already been a few months hopefully you didn't get any induced growth (or it's so minor you can't tell anyway).
IMO, do electrolysis and prioritize the most visible hairs and the areas that you don't like shaving everyday. With electrolysis, time equals money so the more hair/area you want to cover, the more it will add up.
