When using Melano TX cream, it is generally recommended to apply it only on the pigmented areas rather than the entire face. This is because the active ingredients like tranexamic acid, kojic acid, and arbutin are targeted to reduce pigmentation and lighten dark spots.

Applying the cream only on affected areas helps to avoid unnecessary exposure of the entire skin to these potent ingredients, which might cause irritation or sensitivity if used broadly.

However, always follow the instructions provided by your dermatologist or the product leaflet. If you have sensitive skin or any concerns, consulting a dermatologist before use is advisable.

Key points to remember:

• Apply Melano TX cream only on pigmented or dark spots.
• Avoid applying on unaffected skin to reduce risk of irritation.
• Follow your doctor's advice or product instructions carefully.
• If irritation occurs, discontinue use and consult a dermatologist.

This approach helps to safely and effectively target pigmentation while protecting your overall skin health.
