Melagenina Plus is a topical product developed in Cuba for vitiligo, containing an extract of human placenta together with calcium chloride. The proposed effect is stimulation of the cells that give skin its colour (melanocytes), encouraging proliferation and melanin production. The approved product information specifies application once daily, at 24-hour intervals, rubbed onto the depigmented areas, and without exposure to an infrared lamp or sunlight.
Setting realistic expectations matters particularly here. Response in vitiligo is measured in months; the face and neck generally respond better, while the backs of hands and feet, the fingertips and the area around the lips repigment far less. Where the disease is active — that is, patches are spreading quickly — the first aim is to halt activity, usually with topical or systemic treatment.
The evidence for Melagenina Plus in international peer-reviewed literature is limited. Most published studies are single-centre, lack a comparison group, or use non-standard outcome measures. Better-defined options exist in vitiligo: topical corticosteroids, calcineurin inhibitors, narrowband UVB phototherapy and, in selected cases, surgical melanocyte transfer. A responsible assessment includes whether those options have been exhausted for this patient.
For this reason a dermatology file should not consist of photographs alone. When the patches began, whether they have spread in the last six months, which treatments were used and for how long, the presence of accompanying autoimmune conditions such as thyroid disease, and current medication all directly affect the suitability decision.
