What Is Vitiligo?

Vitiligo is an autoimmune condition in which the immune system destroys melanocytes - the cells responsible for skin pigmentation. This results in white patches that can appear anywhere on the body. Vitiligo affects approximately 1-2% of the global population, with higher prevalence in the Middle East.

Two Treatment Approaches

Approach	Goal	Best For	Permanence
Repigmentation	Restore color to white patches	Limited, early vitiligo	Variable
Depigmentation	Remove remaining pigment for uniform appearance	Extensive vitiligo (50%+)	Permanent

When Is Monobenzone Used?

Vitiligo covering 50% or more of body surface area
Repigmentation therapy failed after 12+ months
Patient has made an informed decision about permanent depigmentation
Treatment supervised by a qualified dermatologist

Monobenzone produces permanent, irreversible depigmentation. This decision cannot be undone. Always consult a dermatologist before starting.

How Monobenzone Works

Monobenzone (MBEH) destroys melanocytes through two mechanisms: free radical generation (permanently destroys pigment cells) and tyrosinase inhibition (blocks melanin production enzyme). The result is permanent, progressive lightening of treated areas.
