I've recently read about a new kind of girls get together called a Trash it or Treasure it party. I've known that they existed for clothing but I had never heard of one with a beauty theme. You can read more about it at Sunnie Brook Beauty Blog. There are some important guidelines listed to let attendees know how to tell if the products you're interested in bringing could be expired.
I would totally take part in this party! However, I would only be interested in products that you can individually dram out i.e. not something that you have to dip into the jar for. This would exclude makeup that is pressed into a compact (blush, powder). I would also have to exclude any eye makeup because I just think that is gross. I would be inclined to rule out nail polish too, although I am told that the formaldehyde in it kills any bacteria or fungus I just wouldn't want to take the chance.
It would be perfect for trying out shampoo, conditioner, lotion (face or body), hair styling products, beauty treatments (face masks), self-tanners, bronzers, face wash, makeup brush cleaners, makeup brushes...the list is long.
Because who hasn't a purchased beauty product that they have instantly regretted or immediately disliked? I know it isn't just me.
Also, let's exclude toothpaste and dental floss. You know somebody would try to bring that.
