Hi!

I'm new here and I'm considering skin bleaching.I wondered if I could layer skin bleach?
For example, I'd use a product that lightens maybe two shades and another one that lightens 2-3 shades giving me an overall lightening 4-5 shades? Is that possible or am I just being downright silly?:o

You're being silly. Using something with concetration of 3% and 2% hydroquinone, will not give you hydroquinon of 5%. It will actually have an averaging effect on your skin. The Obagi Nu-Derm works really well though. My moher uses it and er skin is beautiful. It is expensive however a great investment.
