The "Micro-dermabrasion" caught my eye because I need a scrub that has tiny beads in it. I wanted to purchase Clarasonic or PMD's micro dermabrasion device but it costs too much for me, so I went ahead and got this.
The package says use once a week and I think it's accurate. The beads are so tiny but it really does gets into your skin. After usage my skin feels so nice and exfoliated. I used to have flakiness around my nose and now it's completely gone.
It's easy to wash it off and doesn't leave any residue. It doesn't break me out and I think this is one of the best scrub I've ever tried yet.
I used a tube of this and while it is an effective exfoliator, be warned that it's very abrasive. This is not plastic beads or ground up seeds, but aluminum oxide crystals. (If you ever used Avon Anew's micro-dermabrasion exfoliator from ages ago, you'll find the Boots very similar.) It's definitely something that should only be used once or twice a week and follow the instructions to only scrub for a max of 60 seconds. Otherwise you'll basically tear your skin up.
It's meant to be used on already cleansed skin. It rinses rather easily and doesn't leave a residue. But beware if some gets in your mouth as you scrub near your lip line -- it's like sand in your teeth. It comes in a soft plastic tube with a flip-top, so easy to dispense in the shower and easy to use every last bit. It's not the cheapest exfoliator out there, but considering how powerful it is, the price isn't bad, especially with the relatively frequent £5 off Boots vouchers. I don't know that I'd pay full price at £11.
Although I'm not rushing out to repurchase, as I think it's a bit harsh for my skin, I won't say I'd never buy it again. My face definitely felt smoother after using it; it does work. So I'll keep it in mind if I need something with a bit more "oomph."
