I always love these types of threads as I get so many useful tips from them!
For me
BedHead Small Talk - for lifting limp hair - it's not super cheap but a tiny bit goes a long way. Use it every day
Rimmel ScandalEyes kohl pencil and Made by Mitchell All Smudge No Budge eyeliner - I wear eyeliner most days and these stay on for 12+ hours, and look really sharp - about £9-10 each
ELF Pout Clout pens and their glossy lip oils - about £8 and look and feel nice
Ponds cold cream - have tried other, fancier cleansers but keep coming back to this
The Ordinary 0.2% retinol - also about £8 and use it almost nightly - together with marine collagen it's made a big difference to my skin
