| Beeswax. I'm seriously allergic to bee propolis. Its really not that uncommon, I'm always shocked that companies don't post a possible allergan on the label instead of cramming the "all natural, buy this product" speech all over the place. |

There you have a very important point! There are more people who are allergic to things that have to do with bees, like beeswax and propolis.
Just goes to show how VERY IMPORTANT it is that skin care companies comply with the rules and give a complete ingredient list! |

I'm curious as well.
I've read the specific scientific reports, in the past, about the very real danger of DMAE definitively causing cell death,
but also read somewhere that some small percentage range of DMAE is, possibly, quite beneficial, acceptable, and allowed in topical skin products by the, I think, some federal government regulators. (or something like that) |

Dr. J,
I know I don't really need to ask but I was wondering what you thought of Lancome's new cream. The magic ingredient is supposed to be rose stem cells (2 million of them in each jar of cream). http://www.lancome-usa.com/absolue-lextrait/absolue-lextrait,default,pg.html#/section/2/1
Do people really sit around in a meeting and think, what can we call this process, I know we'll call it Fermogenesis. They just make up a new word and trademark it! And, they have Julia Roberts as a spokesperson. $350 for 50 ml.
What do you think?! |
Total and complete bunk. What I really think I am not allowed to say.
You can isolate the "stem cell like" cells of a plant from a tiny area of ~35 cells in the apical root, called the meristem). That's 35 cells per plant. (In contrast, we start with
about 500,000 whern we start a culture of human cells). Now, plant cells are slow growing in culture. The population doubling time is weeks. So, in order to get to 2 million plant stem cells, you would need (let's see 35, 70. 105 ... etc) somewhere around 2 years to get to 2 million cells. That's one jar - let's start on the next.
In other words, work from the biomass equations, you find out is is bloody impossible to do this commercially. Unless you want to start with maybe 100,00 roses per jar. That would be pretty high cost of goods, mind you. Somebody is fibbing. |

Some sunscreens irritate my skin.
However, mineral-based sunscreens, such as those featuring zinc oxide and titanium dioxide, seem to be okay for me. |

I can't tolerate any chemical sunscreens they make my eyes tear horribly! |

| I can't use chemical sunscreen on my face either, though I can use it on my body. IF I use chemical sunscreen on my face my eyes swell shut. I have used several great physical sunscreens such as Raw Elements (very thick though), Thinkbaby, Beyond Coastal, even CeraVe Am (which does have a few chemicals, but no avobenzone). I think it's the avobenzone that causes the problem. CeraVe doesn't have it. |

| Also, I forgot to add this. If you are going to an island location for vacation you should only use a physical sunblock that is "reef safe". The chemicals in chemical sunscreens bleach and kill coral. In fact, many islands areas won't even sell chemical sunscreens. Actually you should only use a physical sunscreen any time you are going to any ocean side resort and swimming in the sea. |
