Kosmea is an Australian skincare brand that's still owned and run by an Australian family. I don't know the whole story of how rose hip oil got so popular, but Kosmea Rose Hip Oil is the only one that claims to be the original rose hip oil, so I'd take their word for it ;)
Unlike most other rose hip oils, Kosmea rose hip oil isn't South American - it's sourced from certified organic, hand-picked rosehips from Lesotho in Africa, which supports the local community. The oil is extracted from the whole rose hip (seed, skin, and fruit) using a supercritical CO2 process which doesn't require heating, which means far less of the unstable nutrients in the oil are destroyed during processing.
(A'kin Rose Hip Oil, which I reviewed earlier, also uses a supercritical CO2 extraction process, but with Chilean rose hips, and the seeds only. In one study, oil from whole rose hip fruit was found to have a higher carotenoid (vitamin A) and tocopherol (vitamin E) concentration. I have no idea whether Kosmea Rose Hip Oil has a higher antioxidant content, or whether this results in an observable difference when used on skin.)
Just like A'kin Rose Hip Oil, this absorbed quickly (maybe a tiny bit quicker) and has left my skin clear and glowing. Kosmea's (left) is slightly darker than A'kin's (right), but neither makes my skin noticeably different in colour when rubbed in... perhaps if you're incredibly white you might see a difference?
Kosmea oil smells slightly stronger than A'kin oil, but the scent disappears after a minute. I don't find it unpleasant (kind of musty), and it's easily covered up once I put my moisturiser on over it.
I can't really tell the difference between the two in terms of their effect on my skin - how do you tell the difference between astounding and breathtaking? I have nothing but praise for both these brands of Rose Hip Oil - all the fangirly gushing I did in the A'kin review equally applies here!
Are there any other brands of Rose Hip Oil you think I should try out?
