Contact leukoderma, or hypopigmentation, from bindi wear is characterized by white marks on the forehead due to localized loss of skin pigmentation. This condition is caused by prolonged contact with adhesive chemicals in bindis, such as para-tertiary butylphenol (PTBP). These chemicals can trigger an inflammatory response, damaging melanocytes - the cells responsible for skin pigmentation. The condition is more noticeable in darker skin tones due to the contrast between depigmented and normal skin.

How to Prevent Contact Leukoderma?

Prevention involves using hypoallergenic bindis, switching to kumkum powder, or alternating bindi placement. If white marks develop, discontinuing bindi use in that area is crucial. Treatment options include topical corticosteroids or repigmentation therapies prescribed by a dermatologist. Early intervention can lead to gradual repigmentation once the irritant is removed.
