The confusion between sweat and skin oil
Many people believe that sweating makes the skin oilier, but this is a widespread misconception. The reality is that sweat and skin oil (sebum) are two completely different things , with different functions and produced by different glands.
Understanding this difference will not only help you better understand your skin, but also help you make better decisions in your skincare routine. Let's debunk this myth with science.
🔬 Sweat vs. sebum: what they are and how they work
Sweat: to regulate body temperature
Sweat is a liquid composed primarily of water, minerals (sodium, potassium), and toxins that the body eliminates. It is produced in the sweat glands, whose main function is to regulate body temperature .
When it's hot or we exercise, the body releases sweat to cool itself. But this fluid has nothing to do with hydration or the oil in our skin.
Sebum: the skin's protective barrier
Sebum, on the other hand, is a mixture of lipids and ceramides produced by the sebaceous glands. Its function is to protect the skin, maintain its elasticity, and prevent water loss .
That is, sebum is what actually makes skin feel oily, not sweat .
🚫 Does sweat cause acne or oily skin?
When you sweat, your skin may feel damp and sticky, but this doesn't mean you're producing more oil. In fact, when sweat evaporates, it can cause a feeling of dryness.
However, if sweat mixes with impurities and isn't properly cleaned, it can clog pores , leading to the appearance of blemishes. The key is to maintain good hygiene without damaging the skin barrier.
💡 Keys to taking care of your skin if you sweat a lot
- Proper Cleansing : Use a gentle, sulfate-free cleanser to remove sweat and impurities without disrupting the skin barrier.
- Light hydration : Opt for light formulas to replace lost water without adding heaviness.
- Don't overuse mattifying products : If your skin sweats but feels dry, what you need is to hydrate it, not remove more sebum.
- Avoid harsh wipes : Using alcohol wipes can disrupt the skin barrier and cause your skin to produce more oil to compensate.
- Change your clothes after sweating : In the case of body skin, leaving sweaty clothes on for too long can promote the appearance of pimples on the back and chest.
📚 SCIENTIFIC SUPPORT
According to dermatological studies, sweat itself is not responsible for acne or increased oiliness. In fact, an article from the American Academy of Dermatology highlights that maintaining a balanced cleanse and avoiding harsh products is key to healthy, balanced skin.
