Natural deodorants are really hit or miss - mostly miss!

: I've wasted enough money on them to know. I have yet to find anything really great, but my current combo of using the crystal stick (I use Lafe's but also heard thai is good) immediately after showering then putting some Now long lasting deod cream (their version of the famed Lavilin, wchich now has chemical junk in it

THe Now also comes in a stick) seems to work the best. I still sweat and sometimes have to reapply if I'm out in lots of heat. It's the aluminum in the antiperspirants that makes them particularly bad. If you can't convince her to go natural, maybe just getting a commercial one w/o the aluminum in it? I've tried Adidas deod (not antipersp) with "cottontech" and it does help control sweating along with odor. It unfortunately has troclosan (antibacterial) in it, though.
For facial care, when I wasn't making my own with honey, etc I really liked Juice Beauty and Mychelle. Both are pretty natural and have some acne-specific products. Unfort. both are $$$ hence my switch to honey and other natural things with those products as an occasional boost. I also like the Burts blemish stick. Helping her skin will be a multipart approach though. Making sure she gets plenty of water is key. I also find adding probiotics, B vitamins and cod liver oil (high in vit A as well as EFAs/omega 3) to help immensely. You'll also want to teach her to be careful about readingf labels (natural or not) because there are some ingredients that are very comedogenic always (SLS/SLES, wheat germ oil, cocoa butter) and some that can help one person while triggering breakouts in the next (coconut oil and shea butter, for example). Be diligent about hand creams (hands go on the face often), hair products, etc in addition to make-up and facial products. You'll be SHOCKED to see just how many "acne" or "non-comedogenic" products actually have comedogenic ingredients in them! A good site for info on ingredients to avoid is
http://www.zerozits.com/Articles/acnedetect.htm Their products are full of chemicals but I like their database of ingredients rated by potential for conedogenic effects.
In the end, I agree to an extent with what the PP was saying but wouldn't completely let her choose something I feel is harmful. I'd really start working with your DD on respecting her body in general so she'll *want* to be more mindful of what goes in/on it. Also, teaching her (or maybe leaving some "breadcrumbs" but allowing her to stumble on the info herself) about WHY conventional antipersp is so bad, and why these chemicals are so bad to put on your skin may be the better route. It may take a while but I'd *hope* that as she learns about what these things can do to her body, her future fertility, the environment, her skin in the future (lots of chemicals are thought to cause premature aging/wrinkles) she will *want* to avoid them without any motherly "nagging", KWIM? The EWG skindeep site has lots of good info and links. Also try the green guide. If you feel strongly she should only use natural and she is just dead set against it, maybe try a compromise. Look at the EWG ratings for each product in question and tell her she can choose whatever she wants so long as it has a rating of (X) or better (look at them yourself first and pick what feels like a good compromise to you).
Good luck! I hope you both find something that works!
