I bought some acrylic storage from Amazon Haul and that has helped me to tidy stuff and to see what needs using up. I also have lot of skincare in various beauty bags in cupboards but I do know/remember what’s in them and bring it out when something else is finished.
I’ve mentioned before the cute plastic boxes you can get in Primark. Mine are fixed, but some are foldable for when not in use.
I have far too much moisturiser atm - lots of the ‘good stuff’ but also went a bit bonkers in Aldi months back and have industrial quantities of their dupes to get through. The never-ending night cream finally emptied this week and I swear I did a little victory dance round the bedroom. (Now, if only the ELF day moisturiser would finish too, but sadly there’s no end in sight!)
Meanwhile I get through loads of eye creams and EL eye serum and their anti wrinkle serum 🤷♀️
Re: Haul - for things like the acrylic storage pots, they come from the same sellers as on Amazon proper, just cheaper.
