trying to use what i have instead of blindly decluttering

i already purchased it right?? and decluttering leaves this empty space in my collection that makes me want to buy more. on my youtube (ill link in the comments but no pressure to watch LOL) i’m starting a makeup probation bag where im going through my products and deciding what im not using enough and giving it a second chance. i want to buy LESS thats the main goal. do you also feel like decluttering makes you want to buy more crap? or substitute? it all ends up as trash so it’s better to not buy in the first place imo. or at least be very cognizant of what you decide to buy.
