Among the most important vitamins for color regulation is vitamin B12. When B12 levels drop too low, the processes involved in normal cell growth and pigment formation may slow down. In some people, this can contribute to lighter patches or uneven tone.
Individuals who follow vegetarian or vegan diets, as well as those with absorption problems, are more likely to experience B12 deficiency. Another essential nutrient is vitamin D, which supports immune balance and general skin function. People with little sunlight exposure or who live in areas with long winters may have lower levels of this vitamin.
