Whats the best makeup for sensitive skin?  

I like physician's formula. It is on the expensive side, but specially made for people who have sensitive skin. The story behind the company is the doctor who started it fell in love with a woman who had extremely sensitive skin, the makeup has ZERO fragrance and other known skin irritants AND comes in all kinds of colors and styles for everyone. They have eye makeup (safe for contact lens wearers!) concealer, mascara, eyeliner, anti aging lines, cleansers, foundation, etc etc etc. The eyeshadows are especially neat, they can be applied wet or dry for dramatic looks or natural looks. LOL I sound like a commercial but I really like it. Here's the website if you want to check it out! :D :D

I have extremely sensitive skin as well. The only two brands of make up that I can use are Christina Valmy (available only in her salons and very very pricey) and Bare Minerals (not cheap but a lot less pricey). My skin is not only sensitive but it is also extremely dry and vasoline is the only other thing that I can use on my skin. Sensitive skin is very frustrating isn't it?

All right, the trick is not to use store bought makeup. You won't believe the stuff they put in it, and it causes lots of skin problems, and aggravates acne and stuff like that.
If I where you I would check into handmade mineral makeup. I know it sounds weird, but that's what I use, and it's really awesome! The crushed minerals are good for your skin, and I have found that my face has actually been clearing up since I started using it. It looks just like professional makeup, but it's healthy.

You can check out my blogpost about it if you are interested. I have links there to some Etsy shops where you can buy it. I really encourage you to give this a try, I think you'll like it! My blog is http://www.etsytreasurechest.blogspot.com

Good luck!

Use some product which can prevent the sensitiveness. Avene is a good choice.
