Safest bleach for acne prone skin

Hey guys as i already said that its my wedding in feb (feb 14 :)), i have started going to parlor for cleaning and all. i go for some lotus gold sheen cleaning (done with only gels, as they say). it suits my skin and in fact helped my marks get lighter, and a lot less whiteheads. but now the problem is that its just 20 days left for my wedding. and the (parlor girl :P) told me that i will have to use facial bleach for the next two sessions (some lotus gold bleach), for glow on skin. but i am quite worried because i havent used any bleach ever. i dont know how my skin will react to it. i dont want to irritate my skin at this time (better not to have a glow but a clear skin). what should i do? is there any way i can test the bleach before actually using it on my face?
