I've been waiting for a post like this!.
My skin is not very problematic at all so yes, I may be lucky but it is also not perfect in any way
I am 35 and in various stages of my life (and finances) I have used Liz Earle, L'Oréal, Elemis, No 7, Clarins, Lush (the £35 one!),Olay; Elemis. Soap and Glory, Clearasil, and more ....from the cheapest to the most expensive.
NONE of them have made any discernible difference to my skin. I'm often told I look like I'm in my 20's despite drinking and smoking etc. I know that won't last but would LOVE to find skincare that seems to make any kind of difference because otherwise, I've wasted A LOT of money for no reason.
Now, I exfoliate with poundshop scrubs and use poundshop moisturisers.
That may mean I'm lucky but I would love to be able to slap something (anything!) on while thinking it's worth the money and makes me look better!.
