If all these changes are visible on the skin then it may be due to deficiency of this vitamin and not due to fatigue!



The body needs adequate amounts of Vitamin B12 to stay fit and healthy. This essential nutrient plays an important role in DNA synthesis, energy production, formation of red blood cells and proper functioning of the central nervous system. As age increases, the body's ability to absorb vitamin B12 decreases, leading to deficiency. However, deficiency symptoms may be seen even at a younger age. Recognizing and addressing these signs is important for overall health. Here are 5 skin signs that may indicate vitamin B12 deficiency:

Yellowness of the skin:

When there is a deficiency of Vitamin B12 in the body, the skin starts appearing yellow. This is because the deficiency may result in reduced red blood cell production, leading to yellowing of the skin. It is not advisable to ignore such signs.


Inadequate levels of vitamin B12 may contribute to the development of acne on the face. Vitamin B12 is essential for skin cell reproduction and its deficiency can cause acne. If acne persists, it is recommended to include foods rich in vitamin B12 in the diet.


Vitamin B12 deficiency can cause hyperpigmentation. Dark spots or patches may appear on the skin and the skin color may become darker. This happens when the skin produces extra melanin pigment.

Redness or swelling:

Swelling or redness in the corners of the mouth may be a sign of vitamin B12 deficiency. This condition, known as angular cheilitis, may be accompanied by difficulties eating and drinking. It is important that such a situation is not ignored.

Dryness and wrinkles:

Vitamin B12 deficiency can contribute to skin dryness and the development of wrinkles. This is because vitamin B12 promotes collagen production and moisturizes the skin from within. Deficiency of Vitamin B12 can cause fine lines and wrinkles on the face.
