I'm sorry to hear you're concerned about dull skin.

About Glutathione:

• Glutathione is an antioxidant naturally produced in the body and is sometimes used as a skin-lightening supplement.
• While some people use it to improve skin brightness, scientific evidence on its effectiveness and safety for long-term use is limited and not conclusive.

Safety Considerations:

• Long-term use of glutathione supplements has not been extensively studied, so safety throughout the year cannot be guaranteed.
• Potential side effects may include allergic reactions or interactions with other medications.
• Oral supplements and injectable forms differ in safety profiles; injectable forms should only be administered by qualified healthcare providers.

Alternative Recommendations for Dull Skin:

• Maintain a balanced diet rich in antioxidants, including Indian staples like millets, dals (lentils), fresh fruits, and vegetables.
• Stay hydrated and protect your skin from excessive sun exposure using sunscreen.
• Regular cleansing and moisturizing suited to your skin type can help improve skin texture.

Next Steps:
It is best to consult a dermatologist who can assess your skin condition and recommend safe and effective treatments tailored to your needs. They can also advise whether glutathione or other therapies are appropriate for you.
