I agree with all fellow electrologists: your skin looks ok. Fine hairs can be removed. Reason of re-growing those could be that you sweat on that area too much maybe? Just keep in mind, not 100% sure because could be other factors contributing as well.
I wanted to add: use neem oil for skin imperfections. It’s indian spice, fod category, will never hurt you. It has specific smell though but in my practice NOTHING takes care after electrolysis scars, acne scars and acne itself, redness all kinds of skin conditions, like neem oil. Seriously. I sell it in my office. I recommend to everyone. Any brand will work, just make sure its food grade, because sometimes they use it as plant pesticide and add adder chemicals. You need just NEEM OIL with no additives, food grade and you’ll be fine.
Hope this helps:) Stay safe!
