I got into skin care about 2 years ago. For full disclosure I have had a lower face and neck lift as I had really, really bad Turkey neck due to losing a lot of weight in my late 40's.
After sorting out the 'scaffolding' with that and some subtle Botox and fillers I concentrated in my skin. As I have heard an aesthetician say it would be like going to the dentist without brushing your teeth if you didn't take care of your skin.
I've tried higher and lower end stuff and whilst I think that cleansing/cleanser can be fairly cheap ( it only ends up down the drain after all ) a good acid toner, serum and moisturiser are essential.
Retinol OR retinal is brilliant for that glow and fine lines.
I've recently got into medik8 retinal and you can start off with a lower dose ( like medik8 3 ) eventually working your way up to medik8 number 10. It's supposed to work much faster than retinol and without the irritation.
I've used dermatica and I rate it but got the irritation so stopped.
One thing I have recently discovered via a beauty advent calendar and I really love is Bioeffect EGF serum. Bloody pricey but it's amazing stuff.
I finish off with Sunday Reily CEO vit c moisturiser which I also got in an advent calendar this Christmas and it's honestly one of the best I've ever used ( smells like oranges too ).
I was going to say also if you are of a 'certain' age that hrt helps with not only your bones but your skin too ( I'm 51 ) I've attached a pic so you can get a good idea of my skin now.
I do use Nars tinted moisturiser for a light coat of colour and to even my skin tone a little but in all honesty my skin has never been better 👌🏻.
