Honey. Seriously. I have very sensitive skin, and just squirt a teaspoon or so into my palm every morning, and wash and rinse. (At night, just plain warm water.) Once or twice a week, I leave the honey on as a mask, for about 15-20 minutes (do this in private--it looks DISGUSTING); then I rinse it off. It really softens and makes your skin look healthy (as does drinking lots of water, no smoking or excessive alcohol, and eating properly). I swear it has some healing properties on skin, too. Because it's sticky, I usually use it before I wash my hair every day, in the shower. (Actually, left on dampened hair for 15-20 mins. also helps your hair, though not as well as your skin.) I also use slightly diluted cider vinegar as a toner, and a hair rinse (for shine).
Not to sound moralizing, but I prefer not to use chemical stuff on my skin, if I can help it, not just because of the sensitivity issue, but also because I don't think that stuff (a lot of which is hype) does much, or is very safe in the long run; plus, I abhor animal testing for beauty products. Honestly, I've found that natural, simple stuff is just as good, if not better; and safer, and cheaper. Not to brag, but I've been told I have a lovely complexion (after the teenage acne went away!), and look far younger than I really am (wonder how long THAT will hold up
). I simply try to take good care of myself--no drinking, smoking, nor drugs (god, I'm boring), and I try to eat properly, and drink lots of water. Getting enough sleep really helps, too, but I tend to have trouble with doing that. Genetics help, too! Mom had a beautiful English "peaches and cream" complexion, which I used to have as a kid.
