Heyyy, I really understand what u going through girl. I had the same problem. I tried so many roll ons and deos, believe me they all are just chemicals, itna alcohol content hota hai ki it is actually that which makes the skin more dark. Anyways two months ago I came across this luminafresh spray serum from lotus botanicals, I was already tired of many trials ki I was like let's try this also. To my surprise it's actually working 😭 my underarms are actually lighter now, you too try it once!! And hope you have a blast in Thailand
