What has she got already?
And is she looking for Cruelty Free (my DD is 16yo and we only use CF)
Superdrugs is brillliant , lots of different brands ( Superdrug carry the 'Leaping Bunny' logo) get yourself a Superdrug card and get discount/money back rewards.
Often things on BOGOF/BOGOHP
Brushes - loads of choice. My DD likes Real Techniques
Beauty Blender / equivilant to apply foundation
Eye make-up palletes. I think Revolution does huge ones
There's one that looks like a chocolate bar
Concealer
Brow gel/clear mascara to tame eyebrows
Lip liners
Lipsticks (MUA are £1 a go)
Bronzer and blusher (contouring and highlighter too, she'll want to practice her cheekbones
)
DD uses a powder to 'bake' the make-up (look on YouTube for videoes , I have no blinking clue but its applying a good layer of powder then brushing off the excess)
And finally .................. a good cleanser , eye-make-up remover , some muslin cloths and cotton pads.
No baby wipes !
Are you just goig to surprise her or ask her for clues?
