To be fair a lot of the products I have are left from when I had a blog and was purchasing things to keep up with bloggers that received things in PR.Put stuff that you're on the fence about in a box. If you then use any of the things from that box in the next 12 months, you know it might be worth keeping. Anything else from that box, just toss away/recycle.
Don't feel guilty about getting rid of things. Possessions should serve us, and not weigh us down and make us feel stressed or overwhelmed. Only keep things which are useful or make you feel good.
If you’ve bought too much makeup, maybe take some time to assess why that is? I am guilty of doing this, but mainly because I have a hard time finding colours which suit me. I’m finally getting to a place where I know what suits me, and what won’t.
I made a promise to myself to not buy any more liquid products, as these don’t last long. E.g. lip glosses, liquid highlighters. Powder products last for years if you store them well, and if they contain preservatives (so not products from "clean beauty" brands). I'm glad I kept some powder blushes, eyeshadows and foundations that I thought didn't suit me, but do now.
The only thing I feel bad about is throwing away makeup in packaging which isn't recyclable. So much of it isn't recyclable. I think in the next few years, companies are going to have to (or they should be made to) change their packaging to become recyclable and more eco-friendly - more cardboard, recyclable plastics, metals/aluminium. Why should they be allowed to produce things made of impossible-to-recycle plastic, just because it looks good or cool? I'm talking about the hard coloured plastics and decorative resins some companies use. It might look good on their Instagram pages, but this stuff will take hundreds of years to degrade in landfill.
Really bugs me about packaging especially for products where there are multiple elements so have to be broken down for recycling. Seems to be more brands coming out with refillable products so hopefully that'll be the future.

I'm not sure if they'll take used product but that's a good shout, will check out what they take.If there is a women’s shelter/refuge near you they may be take your unwanted items. Often women flee domestic violence with little more than the clothes they are wearing and are grateful for any gifts.
