Does anyone know the website that says what cheap products match the posh ones for ingredients

[LaurieFairyCake]

I've been searching for an hour and I can't find it

I vaguely remember that Creme de la Mer is almost matched ingredient wise with the plain blue Nivea

I'm looking to 'match' Eve Lom's serum at £57 with a cheaper one

help me please

This?

Hmmm, not sure, but sounds good.

I can tell you that Chanel Vitalumiere and Boots No 7 Lift and Luminate foundation are almost exactly the same thing. Found that out by accident though.

not that one (it doesn't have skincare) but that looks a good site for make-up
