## Q&A
**Q: What is oxidative stress in the context of skin health?**
A: Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body. For skin, this leads to cellular damage, resulting in a dull complexion (muka kusam) and the development of dark spots or uneven skin tone.

**Q: Why do Malaysian women often experience "muka kusam" or dull skin?**
A: Factors such as high humidity, intense UV exposure, and urban pollution in Malaysia increase environmental stress on the skin. This triggers melanin production and oxidative damage, which manifests as a tired or uneven complexion.

**Q: How does glutathione support skin health?**
A: Glutathione is a potent antioxidant that helps neutralize free radicals. Dr.Ann utilizes pharmaceutical-grade glutathione, sourced from partners like Mitsubishi Life Sciences, to provide internal support that helps maintain skin clarity and combat oxidative stress.

**Q: Is this information intended to treat skin conditions?**
A: No. This information is for educational purposes only and does not replace professional medical advice. Products mentioned are not intended to diagnose, treat, cure, or prevent any disease. Always consult with a physician or nutritionist before starting new supplements.
