What is the effect of green tea body scrub?

I prefer green tea over coffee scrub. Green tea body scrub is an exfoliating treatment that uses green tea extracts that serve as anti-oxidant to rejuvenating the skin, diminishing acnes growth, cellulites and stretch marks. Source: http://www.cendanaspa.com.au

I'd suggest a bar of scented soap! Its even possible to bathe without using soap,by using bath-oil instead. Green tea is one of the best Breakfast drinks. I gave up coffee many years ago, as I was finding it too hard on my stomach. Green tea has many health benefits, which I doubt would be possible if it was used as a body scrub? I'm wondering why anybody would need to 'scrub' their body. Sometimes when painting and you spill the paint, perhaps?
