Winter Sports – Protect Your Skin

Suncreen is even more important at high altitude. Look for sunscreens with a good UVA blocker like Mexoryl 3%, zinc or titanium 5-10%. UVA becomes more intense at altitude. It’s a longer wavelength of UV radiation, and it damages your collagen and your collagen-making cells more because it penetrates more deeply, causing wrinkles.

Here’s to a skin healthy holidays!

For a good sunscreen with mexoryl, try La Roche-Posay Anthelios 40. I know that some of the customer reviews at are not that great, but this is a good sunscreen.

For a good zinc-based sunscreen, try SkinMedica Environmental Defense Sunscreen SPF 30. This goes on just a bit white, but you can rub it in.  And you want your skin protected at altitude.

Another good mineral-based sunscreen is Fallene CoTZ SPF 58. Great mineral protection, with a slight tint so it doesn’t make you white, and no fragances or chemical blockers.

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes!
