With you on that. I have never had any issues with a physical scrub. The chemical ones just hurt my skin.It didn't really do much for me, there was eventually a bit of dead skin but i literally soaked myself in the bath for like 40 mins. Nothing crazy though, not different than any other exfoliants.
However, I tried it on my nose. I wouldn't recommend it as it's not meant for face ( I have the green one) but i just used it really gently around my nose which seemed to have a lot of dead skin on it and it did remove loads of it and left my nose smooth.
This made me buy a facial scrub. I've been avoiding physical exfoliation due to bad press it's been getting for years in the interest of chemical exfoliants. BHA and AHA never really worked for me, at best they didn't do anything, at worst they broke me out and dried my skin out.
My skin is so much better now after using the scrub! I'm just going to stick with physical exfoliation now, seems to work much better for me than acids.
