Detailed answer

Vitamin B12 is not known to directly treat hyperpigmentation. Hyperpigmentation refers to the darkening of certain areas of the skin due to excess melanin production. Treatment options for hyperpigmentation include topical creams that contain ingredients like hydroquinone, retinoids, or azelaic acid, which help to fade the dark spots by inhibiting melanin production and promoting cell turnover. In-office treatments such as chemical peels, microdermabrasion, or laser therapy may also be recommended by a skincare professional to address hyperpigmentation. It is important to consult with a dermatologist or skincare professional who can recommend the most suitable treatment for your specific condition.
