RMS Beauty "Un" Powder- reviewed and recommended

RMS Beauty


The only ingredient is 100% silica


Included puff doesn't work very well
November 27, 2012 Reviewed by Marta 6 Comments
My new favorite powder for an invisible matte finish when applied with a brush

RMS Beauty’s makeup line could be said to be unconventional. Even their names – take “Un” Cover Up – imply that this is not going to be your auntie’s war paint. The latest product to join the line up is “Un” Powder, a formula that is 100% pure white silica. Extraordinary.

I am already a fan of RMS Beauty and love the founder, celebrity make up artist Rose Marie Swift (see Kristen’s video interview with her and you’ll love her too). Nonetheless, when I first opened “Un” Powder I had to take a leap of faith. The minimalist white box reveals a white lided pot, which on opening reveals a white powder puff, under which is white powder. Actually, not white powder... dazzling white, super soft and fine white powder. I didn’t quite know what to make of it.

After a cautious start, I have now experimented with the powder puff, a brush, no makeup, over Osmotics Inner Light, over “Un” Cover Up, and over La Vie Celeste’s Crème Foundation. I don’t find the puff works to well. At least with my inexpert handling, I ended up with very small but still visible clumps of white powder. Results are far better, I found, when “Un” Powder is applied with a large fluffy brush.

Applied sparingly with the brush, it is gives a truly invisible matte, I would venture to say, porcelain look. Except that porcelain may imply that the skin looks white and, surprisingly, it doesn’t at all – just very even toned and clear.  Now that I’ve got used to it, I like its effects so much that I give my skin a light dusting over Inner Light ($30) and either “Un” Cover or the LVC Crème Foundation  (it works slightly better with the first two).

The supremely healthy conscious Rose Marie Swift has ensured that the silica, which is this powder’s only ingredient, has been cut spherically, as naturally crystaline silica can be irritating. I haven’t found “Un” Powder to be irritating at all. In fact, I don’t even know that I am wearing it – except that I look more “put together” than I usually do.

    Hi Greta, we have written extensively about silica, its uses and safety in cosmetics. You can read here: and if you have any other questions or concerns about ingredients you can search our extensive database for information:

    I tried the RMS powder in a local beauty store and agree that it has a lovely softening effect. Like Arandjel, though, I am also concerned with the inhalation of silica because silica is bioaccumulative. I stopped using Jane Iredale's Amazing Base because I was concerned about inhalation of loose powder. I would love to know TIA's thoughts on this topic, which may be a concern to many. Can you set our minds at ease? Thank you.

    Paulette that is a good question. There may be something to who finely it is ground or a superior grade of silica. The only other thing I would add is that un powder was really designed to be optimal when used over un-cover to take down any shine. Whether that justifies the price for you is another matter. But if you do try any alternatives we'd love to hear your verdict.

    Hi Marta, I love your website but despite being a regular reader, I on,y came across this review only recently. Can you help me understand how un-powder differs from other 100% silica spheres like the ones supplied by Coastal Scents at a fraction of the price? They make a similar claim at being spherically cut....

    I love rms beauty & have gone thru pots of un cover and lip shines & have most of the lip2cheek so I count myself as a fan :-) but un powder seems a bit of the emperor's new clothes... But happy to be proven otherwise!

    This seems like a great product in terms of coverage, but wat about the health aspect of it? Inhaling powdered silica causes silicosis, and I assume you would breathe in quite the amount of silica putting this on - or?

    Thanks for this review! I was so excited to hear this powder came out because I love Un-Cover Up so much. I can't wait to try it!
