Vitamin B12 supplement: Four signs on your face that show you’re deficient in the nutrient

The first course of action is to identify whether or not you have a vitamin B12 deficiency. According to Dr Rajendran Kannan, his research proposes there are four tell-tale signs of the condition on your skin. These included skin hyperpigmentation, vitiligo, angular cheilitis, and hair changes.
Hyperpigmentation
The American Osteopathic College of Dermatology explained hyperpigmentation is when “patches of skin become darker in colour than the normal surrounding skin”.
