Skin needs:
To be clean, to be hydrated, to be protected from the sun. Those are the 3 fundamentals and none need to be £££
AM
Cleanser
Moisturizer
SPF 50 (separate from your skincare, we just don't put enough on if it's in a moisturizer or make up)
PM
Repeat without the SPF.
If you want to explore anti-ageing, a vitamin C in the morning, a vitamin A in the evening. These are two of the very very few products which have a scientifically proven base in anti-ageing.
Serums: most have no active ingredients but are just super-powered moisturizer but in a formula which makes them more easily assimilated. They'll often be silicone heavy which gives an instant smooth effect though that's cosmetic and temporary.
For specific products its harder to recommend as everyone is different. I chop and change.
ANY cleanser is fine- it goes down the plughole after 30 seconds. It's not going to take 10 years off in those seconds it's on your face. It's there to take your makeup off and the day's grime. If you use micellar water to take your makeup off, then make sure you cleanse afterwards as it isn't great for skin but is fine as a first cleanse. Cleansing with a cloth and warm water exfoliates.
Moisturizer - any for dry skin if that's what you have. Look for glycerine, hyaluronic acid, squalane, in the ingredients. Nivea, Olay, L'Oréal, Superdrug own brand, La Roche Posay Riche and Toleriane all great.
SPF 50 Garnier for face is as good as it gets and as cheap as chips.
If you're interested in exploring vitamin C then you're looking for percentages rather than names/prices or anything purporting to be a Vitamin C that doesn't tell you what percentage it is. It should be between 12-20% and it should tell you so.
Likewise vitamin A/retinol. Lots of posters on here have prescription subscriptions with companies like Skin and Me and Dermatica. If you want to try that route those posters have referral codes that get both of you a perk- iirc you get a month free, they get something.
Otherwise you can try an entry grade retinol (about 0.3%) Most creams containing retinol by the big brands lie at around that percentage. Build up gradually.
I'm currently using:
AM
Boots 7 cleansing lotion for dry skin
Boots N7 vitamin C serum
Toleriane Dermallergo moisturizer
Garnier spf 50
PM
Boots N7 cleansing balm first cleanse
Superdrug vitamin E hot cloth second cleanse
Missha dupe of Estée Lauder ANR serum
Toleriane Dermallergo
I use Tret 0.05 a couple of times a week.
Of these, the N7 balm is a repeat purchase and they'll prise it from my cold dead hands. Best balm cleanser I've ever used. Likewise the Vit E cleanser.
I have dry skin and am 57.
