Understanding the Science of Restoring Skin Colour
Vitiligo is a condition in which the skin loses its natural pigment due to the absence or dysfunction of melanocytes—the cells responsible for producing melanin. Medical treatments are primarily aimed at controlling disease activity and stimulating residual melanocytes. However, in certain stable cases, these cells are either absent or insufficient in number, which limits the ability of the skin to repigment on its own and hence leads to failure of medical treatments including phototherapy.
Vitiligo surgery addresses this exact biological gap. The principle is precise and evidence-based: to reintroduce functional melanocytes into depigmented skin, allowing the natural pigmentation process to resume. These procedures are performed only when the disease is stable, because ongoing disease activity can affect the survival and function of transplanted cells.
Two well-established techniques are commonly used, both grounded in this same principle but differing in execution and clinical application.
Melanocyte–Keratinocyte Transplant (MKTP)
The melanocyte–keratinocyte transplant procedure is based on cellular transplantation. A small sample of normally pigmented skin is harvested, and melanocytes along with supporting keratinocytes are separated under controlled conditions. This cellular suspension is then applied over the prepared vitiligo patch.
Scientifically, this method enables uniform distribution of melanocytes across the treated area, supporting consistent and natural pigmentation. It is particularly effective for larger or irregular patches where precision and coverage are essential. The interaction between melanocytes and keratinocytes helps stabilise pigment production, contributing to durable and aesthetically refined outcomes.
Suction Blister Grafting
Suction blister grafting works on the principle of epidermal transfer. Controlled suction is used to create a superficial blister in normally pigmented skin, and the epidermal layer—rich in melanocytes—is then transplanted onto the depigmented area.
Because this technique preserves the natural structure of the epidermis, it allows for excellent colour matching and seamless blending. It is particularly suited for smaller, stable patches where precision and cosmetic outcomes are key.
What Happens After the Procedure?
Following transplantation, melanocytes gradually integrate into the treated skin and begin producing melanin. Pigmentation typically becomes visible within a few weeks and continues to improve over the next few months. The goal is not merely repigmentation, but harmonious integration with surrounding skin, so that the treated area appears natural and uniform.
Expertise at Dermalaya Clinic
Dermalaya Clinic is a centre of excellence in vitiligo surgery. Each patient is carefully evaluated to confirm disease stability and suitability for surgery. Our protocols are aligned with international standards, and we utilise advanced cellular processing kits to ensure controlled, reproducible outcomes. Every procedure is individualised—taking into account skin type, lesion characteristics, and patient expectations—to achieve results that are both medically sound and aesthetically natural.
Frequently Asked Questions
When performed in stable vitiligo, results are typically long-lasting. Disease stability remains the most important factor in maintaining pigmentation.
In appropriately selected cases, the treated area blends very closely with surrounding skin, especially with MKTP and suction blister grafting.
Procedures are performed under local anaesthesia and are generally well tolerated. Mild discomfort during recovery may occur.
Initial pigmentation may be seen within 3–6 weeks, with continued improvement over 2–4 months.
With proper technique and patient selection, risks are minimal. Adherence to post-procedure care further optimises outcomes.
No. Surgery is recommended only for stable vitiligo. Active disease must first be medically controlled.
