Serum 50 plus skin

[Candlecassie]

What would you recommend please? I am 51.

I don't rate The Ordinary. I'd like just one thing to apply if possible. I am considering Clarins Double Serum but wonder if you can suggest something else.

I use one from Lidl under Nivea Soft.

I'm using the inkey list, polyglutamic and retinol serums

The estee lauder one is expensive but very good

The Beauty Pie ones are good, but nothing beats Tret. I have the one from Skin+Me.
