I haven't got the cactus brush yet, but in the meantime I had a great idea of how to make the one I got (which is too soft) more effective. I trimmed down all the bristles to at least half their length. Now it feels great when I use it

It gives my skin a nice tingle feeling, I follow the brushing with oil. I'm using Linden leaves which has sweet almond oil, grapeseed oil,avocado oil, rosehip oil, and 23kt gold flakes. I let the oil sink in, and then I smooth over with body cream

at the moment I'm using Clarins.
This is the brush I'm using vvvv
