Re: most expensive usefull products???
Oh and to answer the question, it would have to be the Lancôme Brightening Spot Correcting Serum. A while back I had a break out from yet another failed skin care line (sigh) and this serum really helped even out the spots. I don't use it as much now as it's not needed, but I might be replacing it with the glycolic serum altogether since the latter is, i feel, stronger in giving consistent results for long-term use.
