Makeup thoughts:
I second the advice to try tinted moisturiser (Boots no7 City Lights is nice)
And tinted lip balm (Vaseline rose tint in the pink tin is my favourite.)
And also a good mascara (I'm exclusively waterproof these days - post meno my eyes are watery 😔). If you are cool hair tones (blonde, grey, black, dark brown) go for black, if warm tones (chestnut, strawberry blonde, red etc) go for brown.
For concealer, I really like Fit Me by Maybelline.
For brows - Maybelline Build a Brow has gel, spoolie brush and colour felt pen for filling in sparse bits.
Once you're used to putting things on your face, add:
Lipstick close to your own lip colour (I like Max Factor in Firefly), avoiding glitter, shimmer, gloss and matte. Go for a satiny velvety moisturising finish. Smudge a little on your fingertips and pat high on cheekbones for healthy glow.
A soft smudgy eye pencil that highlights your own eye colour. Avoid black - too harsh. Grey and brown shades work well.
Once you're used to colour, add more for evenings, parties, dates (if appropriate!):
A more impactful version of your neutral lip colour (I like No7 Sugar Plum).
A neutral toned eye palette with a range of colours including flesh tones, smoky and highlight shades.
