I'm sorry to hear about the dark spots on your face. Demelan cream is commonly used for treating hyperpigmentation and dark spots as it contains ingredients that help lighten the skin. However, it is important to use it under the guidance of a dermatologist because:

• The cream may cause skin irritation or sensitivity, especially if not used properly.
• Your skin type and the cause of the dark spots need to be evaluated to ensure this treatment is appropriate.
• Some ingredients in such creams can increase sun sensitivity, so proper sun protection is essential.

Recommendations:

• Consult a dermatologist who can examine your skin and confirm if Demelan cream is suitable for you.
• Follow the prescribed usage instructions carefully.
• Use sunscreen daily to protect your skin from further pigmentation.

If you notice any redness, itching, or worsening of spots, stop using the cream and seek medical advice promptly.
