I use an AHA from Paulas Choice--5% RESIST. I didn't notice a huge difference until I started using it morning and night. I'm 38, majorly sleep deprived, rarely have time to exercise....and my skin glows like I'm outside, living a clean, healthy, active lifestyle.

(which I hope to be once my kids are older and start sleeping). I would get some samples from PC and from Sephora and see what you think. The Philip Thomas Roth one is highly recommended, but it was too much for me. I liked the one by REN. The also gave me one from Ole H to try, but it did nothing. Point is, you may need to try a few before you find what works for you. You definitely don't need to spend $250 for this!
