Is putting lemon to whitening underarm cause irritable pain?
I’m not entirely sure what this means, but most probably yes. Putting lemon on your skin is exposing it to a fairly high acid content. Your underarms are also an area that undergoes a great deal of friction, so you will spend all day not only rubbing acid into your pores, but also causing the skin to stick together because of the sugar in the juice, causing more friction. DO NOT put lemon juice on your underarms, it WILL cause irritation and, likely, PAIN.
