I'm Cynthia Garcia. Certified Clinical Nutritionist, skincare founder, and best-selling author.  When I hit my forties, and the rules changed. Half of what I knew stopped working on my own face and body, and nobody was telling women the truth about what actually does. So I went and figured it out, all of it, and I've spent over $1.3 million in the process.

I grew up so broke I used to dumpster dive for makeup, so I don't take a single bit of this for granted. At 48 I feel better than I did at 28, and everything I learn the hard way goes into guides like this one. This is where I'd tell you to start.
