@Angelprincess87 I always get rid of mascara within 3 months. I've had loads of problems with my eyes over the years. I put a sticker with the date when I open the mascara because I'm sad. Eyeshadow will keep up to 2 years.
I usually use mascara to quite fast but would never throw a palette away😱 in six months it would take me atleast a year to even hit pan on a shade, I feel like false lashes and mascara are the only items you would desperately need to throw out as they can get really dirty, only time I would throw a product out is if it’s empty or started to separate😂
