Less is more in my view. You don't need loads of expensive lotions and potions or to inject yourself with all sorts of things.
You need lots of water, healthy diet, no smoking or alcohol. Hat in the sun. Start with the basics.
I use a normal moisturiser with SPF (never used to use spf but have moisturised since I was 11). I upgraded to Nivea Q10 a couple of years ago as I was finding my skin was getting drier. I have very sensitive skin so stick with what I know.
I've never smoked, rarely drink, but drink lots of water (and always have done)as it's the one thing I like since they replaced sugar in almost every squash with artificial sweeteners and I don't drink tea or coffee. I cleanse every night with a hot cloth cleanser, normal cleanser in the morning. I get out in the fresh air as much as possible, even in the rain.
I tried retinal and wanted to rip my face off (going out in the freezing cold was bliss on my burning face). Worst decision I ever made.
I have a phobia of needles, so botox, fillers, surgery is off the cards. I'm 47 with very few wrinkles if any (only when I'm tired do you see them).
I'm surprised my years of caning it in my 20s and 30s haven't caught up with me. Think I stopped at the right time though.
