There are certain products that I am happy buying over and over again. I used to always be tempted by the next new thing, but actually ended up returning to these, as products that do exactly what I want them to.
Max Factor Ageless Elixor Foundation. It feels so creamy, definitely as if there is a serum in it. I like quite heavy coverage, and this gives it to me, without being cakey or mask like. It has an SPF in it, which eases my conscience perhaps more than saving my skin, but it's an added bonus I guess!
Beautiful Brows in Black is my holy grail of eyebrow products. In the past I used to use either black eyeliner or black eyeshadow, and this seems to give me the best of both worlds. You get three stencils and you just apply the powder through the stencil. Easy Peasey. I love the precise definition it gives me. Look how odd I look with my natural colour eyebrows!
Liz Earle's Cleanse and Polish was the best skin decision I ever made. I've since used most of the products in her range, and love all of them.
I have tried and hated many many black eye liners for the rockabilly/retro catseye flick. They get judged on smudging (where they end up on the top half of your eyelid) and general steadfastedness.
The only once I have been pleased with are Mac's LiquidLast and Mac's Gel liner. The LiquidLast lasts the best, but the gel gives a nicer shape, so I sometimes use both for different parts of the same application.
