I use baking soda occasionally too, and like it-- but I'm 32 years old with oily, thick, non-sensitive skin. It definetly depends on your skin type. From what I understand, salt/sodium is better for oily skin, and sugar is better for dry skin. Maybe just try a teaspoon of fine white sugar, mixing it in with a gentle moisturizing cleanser like Cetaphil, or your normal cleanser, and exfoliate your face with it. After rinsing keep your face a teeny bit damp and generously apply a moisturizer.
I have a book called Beauty 911 by Diane Irons. It's fabulous! It's got tons of tips, tricks, and do-it-yourself beauty stuff. I've been meaning to skim through it and collect the best tips and post a thread. Guess that'll be my project for this weekend!
