I was using a bleaching agent to lighten dark spots on my face due to years of acne. I had dark spots scattered all over my face, so I applied the whitening cream all over. I knew the risk before hand, and honestly I doubted it would work, due to failed products in the past. Surprisingly it did work, just not the way I wanted it to. The cream left a couple small white spots under my lip. Luckily It didn't go on a rampage all over my face, blotching up everything, but the two small spots are annoying.
