Full skin routine for £100

[SparrowFeet]

Looking to buy a 50th birthday gift for a friend that is a full skin care routine for under £100
She used to be into Korean skin care but now with children etc got quite lax with it and I know she wants to get her back into it all without ten layers...
Personally I'm using skin and me but not much of a gift just to refer that so thinking cleanser, vit C, spf, then vit A for evening?
Aware loads of cheap bits out there via ordinary but also want it to be a bit 'gifty' so something special in there.
So.. hit me with what you would buy if you would have £100 to spend on daily routine?

Hmmm.....on that budget I think I would go for:

Superfacialist Vitamin C Cleansing Oil - £8
Medik8 C-Tetra Serum - £39
Ultra Violette Supreme Screen SPF 50+ - £34
Alpha H Liquid Gold - £15

The Liquid Gold is an acid rather than a Vit A but is marketed as an overnight facial, so might be good for the 'luxury' effect.

Oooh fab I'd forgot about Alpha H, and could be a nice starter rather going straight in with retinol if she's new to it. Thanks!
