Designer bindis have become a popular accessory, with endless choices available in stores and online - ranging from minimalistic dots to elaborate pearl-studded patterns.
But while these self-adhesive bindis are fashionable, dermatologists warn they may come with hidden risks, including a condition now widely referred to as “bindi leukoderma.”
The problem lies in the adhesives used to stick these bindis, which often contain p-tertiary butyl phenol (PTBP). This chemical is highly toxic to the skin’s pigment-producing cells, causing permanent depigmentation at the site of contact. Over time, the area where the bindi is placed may develop a vitiligo-like white patch.
Hot and humid climates, such as in India, where bindis are traditionally worn, increase the risk because heat and sweat allow chemicals to penetrate the skin more easily. The longer someone wears adhesive bindis, the higher the chances of pigment loss.
Before depigmentation sets in, many people experience itching, rashes, or other allergic reactions. Stopping the use of adhesive bindis at this stage may help prevent permanent skin changes.
Safer alternatives include kumkum, which has been used traditionally for centuries and does not contain harmful chemicals. Homemade kumkum, made with turmeric, is considered especially safe - though it may leave a temporary yellow tint. However, caution is advised with DIY mixes containing lime or ghee, as they may irritate sensitive skin or clog pores.
While adhesive bindis may still be worn occasionally, regular use significantly increases the risk of skin damage. For those with sensitive skin or a history of allergies, kumkum or homemade options remain the safest and most reliable choice.
