Hi roseneath.
I only use a tinted moisturiser, only cheap, I'm not a believer in paying for expensive make up.
I've bought expensive stuff over the years, and it doesn't do a massive difference, so I always go back to what I know. I only use The Natural Collection from boots, it's £2.99. It does the job.(in golden color)
Mascara, I use Maybelline, that's a good one, again cheapish. And just a slick of lippy, always pink,
And an eyeliner. I've green eyes, so I use blue/green/mauve/. If you want a bit of a glow, the natural collection does a bronzer which hasn't got over the top pigments in it, and I just use a big brush and dust all over and a little more on the cheeks. You can always blend, and wipe it off with a pad if you're not happy.
That's it.
Just makes me look human. Also, I have to be careful what I use because I suffer with eczema on my face sometimes, and the natural collection seems to be ok.
Good luck. Try and go into the shop in the week, not at weekends when all the young ones are in there.
