Yeah leucoderma is somewhat hereditary and can happen to your child. leucoderma or vitiligo is a skin disorder wherein the skin develops white patches or spots. The condition is basically an outcome of melanin deficiency, a skin pigment that protects the skin from sun and other harmful radiations. Hence, the skin areas which are deficit in melanin over a period of time turn pale or white, resulting in white patches on the face, hands and legs margined with dark or hyper pigmented skin. The condition causes no organic harm. However, homeopathy treatment and some home remedies for cure, like use of psoralea seeds and red clay in ginger water, or goosefoot, turmeric powder, etc. can help prevent the disorder from spreading and regaining the normal skin pigmentation. Now you just take your decision and do exactly what you want ,not your parent.
