She has got white patches around both the eyes.. looks scaly and dry at the start and then the color changes to white . consulted doctor and they have suggested the tacrovera ointment. Please suggest how long it will take to cure this patches and what is the reason for this patches?

The white patches around the eyes with a scaly and dry appearance that later change color to white could be indicative of a skin condition called vitiligo. Vitiligo is a condition where the skin loses its pigment cells (melanocytes), resulting in depigmented white patches. The exact cause of vitiligo is not fully understood, but it is believed to be an autoimmune condition where the body's immune system mistakenly attacks and destroys the melanocytes. The doctor has prescribed tacrovera ointment, which contains tacrolimus, an immunosuppressant that helps to modulate the immune response and reduce inflammation in the skin. It is commonly used in the treatment of vitiligo to help repigment the affected areas. The duration for the treatment of vitiligo with tacrovera ointment can vary from person to person. It is important to follow the doctor's instructions regarding the application of the ointment and attend follow-up appointments for monitoring progress. In general, it may take several weeks to months to see visible improvement in the white patches, and complete repigmentation may take longer. It is essential to protect the affected areas from sun exposure and follow a healthy lifestyle to support the treatment process. Additionally, maintaining good skincare practices and adherence to the prescribed treatment regimen can help optimize the outcomes.
