I recently picked up Rimmel's Clear Complexion powder when my previous face powder ran out and I've been giving it a go for a few weeks now. As with most high street brands, the packaging is nothing special but it does what it needs to do. It's a compact powder, so easy to take out and about with you without it spilling everywhere and making a mess in your bag.
It does claim to 'clarify' skin and 'minimise breakouts' but I can't honestly say that I've found that to be entirely accurate since I've been using it - I don't feel that it's made any difference either way. It also aims to control shine for up to five hours which I'd say is about right, though if you have particularly oily skin I'd maybe pair it with a primer. If you have dry skin then just a light dusting would do the trick.
This to me seems like a fairly standard powder, there's nothing wrong with it but it also doesn't massively stand out in anyway. It's probably a stable one to keep in your make up bag that you can rely on for a quick fix. I think it'd be ideal (price wise too, it's not expensive) for younger people, just starting out with make up.
