Protect Your Skin Through 140.6 Miles: A Guide for Triathletes
By Base Layer Team, Skincare Science & Formulation
Key Takeaways
Stop letting chlorine, 100-mile winds, and severe UV exposure destroy your skin barrier. Base Layer's no-nonsense recovery guide for triathletes.

You spend six months deadlifting, dialing in your VO2 max, and agonizing over your aero position. Your body is a machine. But look in the mirror after a 3-hour brick session: your skin is shredded.
Between the lipid-stripping pool chlorine, 20mph headwinds on the bike, and compound UV exposure on the run, your face is aging twice as fast as the rest of you. If you are dealing with chronic windburn, deep sun lines, and extremely dry skin before you're thirty, it is time to focus on recovery.
The Failure of Traditional Solutions
Most guys try to fix the damage by slathering on heavy drug-store lotions or standard sunscreen. This is a crucial mistake.
Standard sunscreens sweat into your eyes at mile 10 of the run. Heavy lotions act like a moisture trap, sealing in the aggressive pool chlorine and trail dust instead of letting your skin breathe. More importantly, they do absolutely nothing to repair the structural lipid barrier that the wind just sandblasted off your cheeks.

The Base Layer Solution
Base Layer was engineered for performance, not vanity. Instead of heavily-scented creams that cause breakouts under a bike helmet, Base Layer delivers a lightweight, aerodynamic shield packed with active recovery ingredients.
It uses **Squalane** and **Ceramides** to instantly rebuild your wind-stripped moisture barrier without a greasy finish. Crucially, it incorporates targeted **Antioxidants** to neutralize the deep cellular damage caused by hours of direct sun exposure on the road.
It absorbs instantly, leaves zero shine, and won't streak your face during the marathon block. It is the ultimate recovery tool for extreme endurance athletes.
