Skincare for Movers: How Fitness Shapes Your Skin and How to Protect It

When we talk about the benefits of staying active, most people think about stronger muscles, better endurance, and that post-workout endorphin high. But regular movement also impacts your largest organ: the skin. For fitness and wellness enthusiasts alike, understanding this connection is more than a matter of vanity – it’s a part of true, holistic self-care.

Michelle McDonald, founder of Sásta Skin Health, breaks down the most common skin changes that happen during exercise, why they occur, and how to keep your skin protected and resilient.

Sweat – The Good & The Bad

Sweat has an undeserved bad reputation in the beauty world, but in reality, it’s one of the body’s most elegant detox systems, flushing out impurities and debris as pores open. But if left to linger, sweat mixes with oil, bacteria and dead skin cells, creating the perfect recipe for clogged pores and breakouts. It also temporarily raises skin’s pH, creating a more welcoming environment for certain bacteria

The Post-Workout Flush

That rosy glow you get mid-workout? It’s your body’s cooling system at work. Exercise dilates blood vessels, boosting circulation and releasing heat. For those with sensitive or rosacea-prone skin, the flush can be more intense and sometimes slow to fade. Over time, repeated bouts of intense redness may contribute to inflammation and a weakened skin barrier.

Barrier On The Brink

Heat, friction, and constant moisture can throw your skin’s microbiome off balance. This disruption increases water loss, weakens defences and makes irritation more likely. Without proper recovery, skin can feel tight, dry, or reactive after exercise.
