Why You Break Out After Sweating, And What to Do About It

Hey there,

Let’s be real, after long, hot days or an intense workout, nothing feels more frustrating than looking in the mirror and spotting new breakouts. Sweat is a normal, healthy part of life, but when it mixes with dirt, oils, and bacteria, it can quickly turn into a recipe for acne flare-ups.

This week, we’re breaking down sweat-induced acne, why it happens, how your daily habits contribute to it, and what you can do to keep your skin clear even on your sweatiest days.

In today’s newsletter, we’ll cover:

• Does sweating actually cause acne?

• How sweating may be contributing to your breakouts

• Are sweat pimples the same as regular pimples?

• Struggling with stubborn breakouts?

• Dermatologist-recommended tips to prevent sweat-induced acne

Does sweating actually cause acne?

Here’s the truth: sweat alone doesn’t cause acne. Your body is meant to sweat, it cools you down and even helps remove waste. The problem starts when sweat stays too long on your skin.

Once it mixes with dirt, sebum, and bacteria, it can clog your pores… and that’s when breakouts begin. So while sweat isn’t the villain, what happens after you sweat makes all the difference.

How sweating may be contributing to your breakouts

If you often let sweat dry on your skin, after a stressful day, a commute under the sun, or a workout, you’re giving bacteria the perfect environment to thrive.

Combine this with tight clothing, friction from gear, or headbands that trap moisture, and suddenly your pores are overwhelmed.

This mix of sweat, dirt, oil, and friction is exactly what triggers those annoying sweat breakouts on your face, back, chest, or shoulders.

Are sweat pimples the same as regular pimples?

Pretty much. Sweat pimples are still acne, just triggered differently.

They tend to appear more on the back and chest, especially where sweaty clothes or equipment touch the skin. They’re usually small, red, inflamed bumps that appear after sweating and wearing damp clothing for too long.

You might ask…

Is working out bad for acne?

The answer is yes… and no.

Working out itself is fantastic for your health. It improves circulation, boosts mood, and supports a balanced lifestyle. Sweat is part of that healthy process.

But… if you don’t clean your skin properly before and after workouts or you wear tight, unwashed gear, you can unintentionally set yourself up for acne.

The workout isn’t the problem, poor sweat hygiene is.
