Whether or not vitamin B can be taken for white spots depends first of all on which type the white spots belong to. If it is an ordinary white spot on the face of children, most of them belong to pityriasis albuginea or pityriasis simplex, you can take vitamin B, especially vitamin B complex, and also vitamin B2 orally, and you can also use vitamin B6 cream locally. But if the white spots do not belong to pityriasis alba, such as belonging to vitiligo, there is no point in taking vitamin B. Or if it belongs to pemphigus, there is no point in taking vitamin B either, including post-inflammatory depigmentation spots. Relevant treatment is needed, which can be done with topical glucocorticoids, without oral vitamin medication.
