Like Laura D., I too believe in doing the very, very minimum when it comes to my health, body, etc. I don't believe half or even three-fourths of what I see in magazines or on TV is good for the body--as Laura D. said, it's advertising/marketing. Those products--shudder--have so many things in them that are just plain BAD for you.
My skincare routine? Using Dr. Thayer's Witch Hazel cleaner in the morning and again at night, before I go to bed. If I believe I have to wash my face, I use either pure, clean water or Dr. Bronner's soap. I wear no makeup, and haven't for years. I am 43, and figured out for myself (even the doctors couldn't agree) that I am already going through perimenopause (my mom and aunts all went through extremely early; I've been going through it since I was 40).
The very best thing you can ever do for yourself--and this includes your skin--is to eat a very good, healthy diet. Eat organic. If you drink tap water, buy a filter or a reverse-osmosis system and filter the chlorine and flouride out (as well as all the other ickys in there that they don't tell us about). Quit using flouride toothpaste. Quit eating anything with excitotoxins, quit the pop, quit the processed/convenient foods, quit the fast foods, eat more veges and fruit. Once you start questioning, reading, and noticing what the food industry is doing to your food (most of it's dead), you'll know why you're always so sick. The body can't live and prosper if it's fed dead food every day.
Oh, I was having lots of issues with breakouts on my face and upper back. Once I discovered I was having hormonal imblances and started taking Maca Root (it's a food, not a herb, but you can buy it in capsules; it helps with adrenal and thyroid issues, fatigue, diabetes imbalance, as well as hormonal imbalance) as well as Hyland's combo of homeopathic remedy for Vaginitis (for issues of yeast infection that weren't yeast infection) and PMS (for bad cramps, feelings of ickiness, all those period feelings that are amped about ten times when it comes to perimenopause), I must say, I'm starting to feel like a whole new woman. And homeopathy is actually fairly cheap to buy, when one considers what pharma drugs cost.
And make sure you're drinking lots and lots of good, filtered water. Most of us are horribly depleted in this very basic body need and don't consume anywhere near enough water during the day. Your skin loves water and will thank you for it.
