Sweat & the Skin Microbiome: How Exercise Affects Your Complexion

We all know that exercise is good for our bodies, but did you know it also benefits your skin? Beyond the well-known glow that comes from increased circulation, movement plays a crucial role in maintaining a healthy skin microbiome—the delicate ecosystem of bacteria, fungi, and other microorganisms that keep your skin balanced and resilient. 

 

HOW EXERCISE SUPPORTS SKIN HEALTH

1. Boosts Circulation for a Natural Glow 

When you work up a sweat, your heart rate increases, pumping more oxygen and nutrients to the skin. This enhanced blood flow supports collagen production, speeds up cell turnover, and delivers essential nutrients that help maintain a youthful, radiant complexion. 

2. Encourages Detoxification

Sweating is one of the body’s natural ways to remove toxins, including heavy metals and pollutants that accumulate on the skin. While sweat itself isn’t a direct cleanser, it helps flush out impurities from the pores, reducing the risk of congestion and breakouts. 

3. Supports a Healthy Microbiome 

Regular movement has been shown to positively influence the skin microbiome. Exercise reduces stress—a major disruptor of microbial balance—and helps regulate hormones that can trigger inflammation and acne. Plus, sweat contains antimicrobial peptides that can help keep harmful bacteria in check while allowing beneficial microbes to thrive. 

 

EXERCISE & MICROBIOME BALANCE: FINDING THE RIGHT ROUTINE 

Not all workouts affect the skin equally. Here’s how different forms of exercise impact your complexion: 

- Low-intensity workouts (Yoga, Pilates, Walking): These reduce cortisol levels, lowering inflammation and supporting a balanced microbiome. 

- Cardio (Running, Cycling, HIIT): Increases blood flow and oxygenation but can also lead to excessive sweating, which, if left on the skin too long, may cause irritation. 

• Strength Training: Helps regulate hormones like testosterone and insulin, which can influence sebum production and acne formation.  

 

HOW TO PROTECT YOUR SKIN BEFORE & AFTER EXERCISE 

Before Your Workout

✔ Keep your skin clean but don’t over-wash—stripping natural oils can disrupt the microbiome. Consider B&B Labs’ [Micro-Molecule Gentle Cleansing Solution] (https://bb-labs.com/products/micro-molecule-gentle-cleansing-solution), a microbiome-friendly, rinse-free 3-in-1 cleansing liquid that removes makeup, cleanses and tones skin.   

✔ Apply a lightweight, microbiome-friendly moisturiser to create a protective barrier. Explore B&B Labs’ moisturisers (https://bb-labs.com/collections/moisturisers).

✔ If exercising outdoors, use a breathable, non-comedogenic sunscreen like B&B Labs’ [Tribiotics 360° Suncare] (https://bb-labs.com/products/tribiotics-360-suncare).

After Your Workout

✔ Rinse your face with lukewarm water to remove sweat without over-drying. 

✔ Use a gentle cleanser with prebiotics or soothing botanicals to restore balance. Consider B&B Labs’ cleansers.

✔ Rehydrate with a probiotic-rich treatment essence and moisturiser to replenish good bacteria. Explore B&B Labs’ treatment essences and moisturisers.

 

FINAL THOUGHTS 

Exercise isn’t just great for your body—it’s a natural way to support a glowing complexion and a balanced skin microbiome. The key is to find a routine that works for your skin type and to adopt a post-workout skincare regimen that preserves your skin’s natural defences. So, lace up your trainers, get moving, and let your skin reap the benefits!
