Personally, i'm not the biggest fan of facial scrubs. I always feel like they are too harsh on my sensitive skin; whilst using scrubs I feel like my skin is getting sandpapered and afterwards it even looks like it - my skin always looks red and uneven. Currently there is only one exfoliator I use but it's after I've used a string of bad ones. So here is the list of all I've tried.
1. St Ives Apricot Scrub. I think they have different formulas for different skin types. I'm sure I've tried them all. Too scratchy for me.
2. St Ives Olive Scrub. I fared better with this one. It's a lot more oily and soft in texture and a lot less drying since it's made for dry skin. I can only use this on bitterly cold winter days when my skin peels off from the cold. For the rest of the year it doesn't do much for my greasy t-zone and combo skin. I'd recommend to people with dry skin though.
5. Origins Modern Friction Nature's Gentle Dermabrasion. I got a sample of this product free after buying an Origins moisturiser. I knew I wouldn't like this since I didn't like The Body Shop Microdermabrasion scrub but I still gave it a go. It's definitely a lot gentler than all the other scrubs I've mentioned and I would recommend this to others. I used this only on my t-zone because I still found it too harsh for my cheeks (but then nearly everything is too harsh for my cheeks so I don't blame this product!).
Finally, my favourite exfoliator: Liz Earle Gentle Face Exfoliator
