Makeup, for me, is part of my skin protection regimen on the slopes. I have known women who are lifetime skiers, but never used cosmetics. Their faces age prematurely. Sometmes, when we are young, we don't think about this, but look around the lodges during breaks and you will see faces that are much more lined than they need to be. Now, you may not mind the lines. Some women don't. I'm a bit more vain.
I start with a protective serum, then apply a winter moisturizer that has sun protection. I use a much thicker and creamier moisturizer on a ski day than general wear. After the moisturizer soaks in, I use Shiseido sun protection makeup foundation (SPF42) and a little cream-based blush. On top of that, I apply Shiseido 55 SPF sunscreen. This all sounds like a lot, but once it soaks in, it protects my skin all day and doesn't look at all caked on. Also, Shiseido is very light and pure; I don't get breakouts or feel greasy. I never have a sun or windburned face, regardless of the weather. I am 56 and, despite 25+ years of skiing, I still have good skin.
I do apply eye makeup as well, though I don't use eyeliners because of the potential for raccoon eyes, as mentioned earlier. Again, using cream eye makeup tends to have more of a protective advantage.
I have my routine down to less than 15 minutes.
