body? I used monobenzone 60% cream for 4 months that I bought from a foreign country. The package said it contained methylbiphenyl. Some people said it was not only monobenzone, but contained phenyl hydroquinone. I put it on my face and some was on my mouth. I think some of this got on my tongue and I might have ingested some of these chemicals. I put this cream all over my body and it may have contain methylbiphenyl, phenyl hydroquinone, and monobenzone. What effects do these chemicals have on the body. Does it cause stomach swelling or any other harmful body effects? It caused swelling, skin peeling, and burning the entire 4 months I used it. Will this swelling be permanent? It hasn't gone down yet.
