Q In summer, sun exposure makes the patch borders stand out more, and a white patch appeared where my eyeglass frame rests. How do I avoid these triggers?
A Severe sunburn and skin friction are major triggers that spread vitiligo. It is important to apply sunscreen thoroughly and reduce friction in areas that are repeatedly rubbed, such as where eyeglass frames or bag straps press.
Detailed Answer
Getting burned by strong sun or repeated rubbing of the skin (the Koebner phenomenon) can create new white patches at that site. Also, the more normal skin tans in the sun, the greater the contrast with the white patches, making them more noticeable. When going out, apply plenty of sunscreen, and it helps to reduce the friction of things that continually press or rub the same spot, such as eyeglass frames, watch bands, tight clothing, and bag straps.
Korean Medicine Clinic Perspective
In Korean medicine, such external triggers are read as "a warning sent by an already weakened area." Alongside putting out the fire through trigger management, we also aim to create a robust skin environment where qi and blood circulate smoothly to the periphery so the skin is less easily shaken by triggers.
