Ooh. I love a good routine. Start basic and build up once you know what works for you. I would suggest;
Cleanser - something basic is good enough. I love gel/oil cleansers, and highly recommend Superfacialist Vit C oil cleanser - in Boots. Or, for a nice cream/hot cloth cleanser, Superdrug Naturally Radiant cleanser is fab. Well priced too. If you wear a full face, double cleanse at night, single cleanse in the morning. Use flannels to wash off.
Acid (exfoliant) - start gentle until you know what suits your skin. Rent Ready Steady Glow is good - M&S sell it.
Hyaluronic acid - this is optional. I love it. The Ordinary, Hada Labo, Indeed Labs all do good, well priced options. It grabs moisture from everywhere, makes your moisturiser work harder!
Spritz - Boots Botanics Rosewater spray is fab.
Moisturiser - I prefer gel again, Superdrug Vit C gel moisturiser is great, cheap and imo far better than Cliniques Moisture Surge, which is a similar product. Cream moisturiser wise, Beauty Pies Jeju night cream is lovely. Or the serum/moisturiser from the Naturally Radiant range at Superdrug (and they're always in BOGOF etc).
Hope this helps a bit?!
