Detailed answer

Whiteheads are not typically a sign of a vitamin D deficiency in older adults. Whiteheads occur when pores become clogged with oil, dead skin cells, and bacteria. Vitamin D deficiency can have various symptoms such as bone pain, muscle weakness, fatigue, and mood changes, but it is not directly associated with the development of whiteheads. If you are concerned about your skin, it is recommended to consult with a dermatologist or skincare professional for an accurate diagnosis and appropriate treatment.
