I am, as I often am, indebted to British Beauty Blogger for her review of this remarkable product – Goldfaden MD Doctor’s Scrub – which she described as ‘one heck of a scrub’. Well it certainly should be because the first item on the ingredient list is ruby crystals. BBB is rightly cynical about beauty business claims and brushed the ruby thing off as a sales gimmick. But in this case, there is something about rubies that makes them uniquely suitable as the abrasive agent in a scrub. They are one of the hardest substances known to man.
Chemist’s measure hardness on the Mohs scale. The Mohs scale is one of those ideas that is deceptively simple but very useful. It works simply by assessing a material’s ability to scratch another. So for example flint, or quartz to give it its chemical name scratches gypsum, so it is harder. Quartz rates a 7 on the Mohs scale, whil gypsum only scores 2. The hardest material of all is diamond, which gets the top rating of 10.
Ruby is just beaten by diamond, but still scores a 9. Normal sandpaper would score about 7. So this is seriously abrasive material and I am not at all surprised that BBB found it to be effective. Quite rightly she advises people with sensitive skin to be careful with this scrub. We are talking industrial level scrapability here.
Scrubs are designed, or at usually designed, to remove the dead cells at the surface of the skin and reveal the fresher younger skin below. You don’t really want to take off more than the thinnest layer from the surface. Go much deeper and you risk impairing your skin’s barrier function. Go further still and you can right down to the dermis and possibly even make your skin bleed. This isn’t going to improve your skin at all, it will damage it.
Most people know what they are doing with scrubs and get the results they want from them. If you want to try this one, bear in mind it is going to be a lot harsher than what you are used to. But some people seem to really enjoy the scrub experience and if you fall into this category then this might be one for you. It does also contain some seaweed extract for whatever that is supposed to do and hyaluronic acid which is a good moisturiser – though this is hardly the product to get the best out of it.
The other striking feature is the very high price – it is in the £60 bracket in the UK. This price might sound steep for a scrub, but this is going to be a difficult product to manufacture. The rubies are going to grind away stainless steel with ease so it will have to be made on plant that has been specially adapted. This applies not just to the tank it is mixed in but the filling line as well. I imagine this will add a lot of cost.
So this is likely to be an interesting experience. I have to say that I was somewhat astonished when I realised what the proposition was. But I really shouldn’t have been. There is no idea too eccentric or far fetched for somebody somewhere in the beauty business to put it into a product.
(I am trying out a new way of writing posts by ex-temporising about them first straight to camera. I’ll see how well this works, but here is the video this one was based on. If you like hearing people say umm a lot you might enjoy it.)
