This question is a bit tricky! It's important to understand that skin tone is primarily determined by genetics and melanin production, and exercise alone won't change that.
However, there are a few reasons why someone might appear fairer after a gym session:
- Increased Blood Flow: Exercise increases blood flow to the skin, giving it a temporary rosy hue. This can make someone appear "fairer" compared to their usual complexion.
- Sweating: Sweat can wash away dirt and grime on the skin, making it look brighter and more even-toned.
- Improved Circulation: Regular exercise improves overall circulation, which can contribute to a healthier and more radiant complexion.
It's crucial to remember that these effects are temporary. Skin tone is determined by a complex interplay of factors, and exercise alone won't permanently alter it.
