I make makeup for a living...I work for a pretty big well known company....we test our makeup for stability at 50C (122F), for five weeks, if it doesn't pass (smells funny, seperates, ect. we have to reformulate. 122 degreees is pretty hot, but a hot car in the summer can reach over 120-160 degrees. At that temperature, lipsticks and hot pour formulas can melt. Some emulsions can seperate. Powders, pressed or loose, are generally fine. As far as bacteria growing, most products (at last the ones from the bigger companies) are very well preserved (sometimes overpreserved), especially if they contain drug actives like SPF ingredients or salicylic acid. I wouldn't worry too much about vitamins breaking down, since makeup contains very tiny amounts of them anyway (even the expensive brands).
It's generally not a good idea to leave sunblock in in your car, for more than a few days (I know people who do this all summer). Sunscreens contain a high level of SPF ingredients, and the high temperature can cause them to break down, and slightly reduce the SPF of the product.
I have done this. I keep two folding coolers in the trunk for anything that needs to avoid being warm.
One cooler is small and I keep any makeup items and pills in there all the time. I even put my car CD's in there on a really hot week. I do not use ice in it the idea is just to keep it at normal temp when the car is at 95 degrees inside. A small foam cooler would work just fine also.
Then the other larger cooler i use if I have to buy foods at the store that need cooling but I cant get home right away. Works like a charm.
I totally know what you are talking about. I have a hard time finding my shade too (and I have pretty fair skin. Everything is too red....I can't wear any of the shades in any of the lines of foundation that my company makes, which is a big mass market company. The department store stuff is too expensive for what it is and I refuse to spent that much money on something I can make myself. Sometimes I get creative and make my own shade myself. But my skin breaks out from anything, so I can't use much of the makeup that I make at work (even the anti-blemish ones). I kinda like that Bare Minerals stuff, it has a low breakout factor and a nice finish, and decent shades, but it's kinda pricey...
I've been working in this industry for almost five years....I am becoming very disillusioned the marketing and advertising side of the industry. A lot of the time there is a marketing "story" around a product talking about all these vitamins and botanicals and whatnot....but usually most products, even the department store ones, only contain very tiny amounts of these compounds, not really enought to be active, they're just in there so that the company can make a particular claim about a product.....
I have the same problem as my skin needs a slight correction from its natural pink. What you want is a makeup with a touch of yellow in it. Heres what worked for me over the years.
1. Going to an expensive beauty salon and having makeup professionally mixed. They would save the recipe and if I needed more could mix it up.
2. Perscriptives has makeup with a slight yellow tone.
3. I use Origins makeup now. I like thier blush too with the warm brown yellow pink tones. Looks like natural but better. Try thier eyebrow pencil, i use the blonde one. Wow do I ever love it.
That's a good idea. I have one of those refrigerators that plug into the cigarette lighter socket (it's not called that anymore, I can't remember what they call it!) and it's essentially a cooler if we don't plug it in. My sunscreen is at home but my husband keeps one in his golf bag in the trunk.
