Protect Your Face During the 100-Miler: A Skincare Guide

Running 100 miles through the mountains builds absolute endurance, but it accelerates facial aging to a horrifying degree.

The repetitive impact, hours of unprotected UV exposure, and the drying effect of alpine wind are bad enough. But the real damage comes from your sweat. As you run for 24 hours straight, your sweat evaporates, leaving behind jagged, microscopic salt crystals on your face. This salt actively draws deep moisture out of your pores while simultaneously acting as sandpaper, causing severe micro-chafing across your cheeks.

The Failure of Traditional Solutions

Applying a thick layer of generic petroleum jelly at aid stations will destroy your ability to regulate heat.

Heavy ointments trap your body heat, pushing your core temperature dangerously high during an ultra. Standard sunscreens melt directly into your eyes within three miles, causing excruciating stinging. If you use normal soap post-race to get the salt off, you chemically burn the micro-lacerations caused by the chafing, making the pain significantly worse.

The Base Layer Solution

Base Layer is the ultimate, clinical post-race recovery complex.

It is specifically formulated with a massive concentration of **Centella Asiatica**, an advanced botanical that rapidly cools the skin and neutralizes the red, painful micro-abrasions caused by 24 hours of salt chafing and windshear. It then floods your highly depleted skin with **Ceramides**, structurally rebuilding the moisture barrier you completely destroyed on the trail.

It absorbs instantly without leaving a sticky, heavy residue that traps heat. Finish the 100-miler, wash the salt off, and apply Base Layer to structurally repair the damage.
