Dry, Flaky Skin: Which Vitamin Deficiency Is Most Likely?

Which vitamin deficiency causes dry, flaky skin?

Several nutrient gaps can show up on your skin, but the vitamin deficiency most often associated with dry, flaky, rough skin is vitamin A. Vitamin A helps support normal skin cell turnover and barrier function; when levels run low, skin can feel tight, look dull, and develop persistent flaking.

Vitamin A deficiency: the classic “dry and scaly” pattern

Low vitamin A can contribute to a buildup of dead skin cells and a weaker surface barrier, which makes moisture escape faster. If your flakes are stubborn even with a gentle routine, vitamin A is one of the first deficiencies to consider—especially when dryness is paired with rough texture.

Other deficiencies that can make skin look dry or flaky

Dryness isn’t always one vitamin. Our team often sees dryness overlap with these common shortfalls:

Vitamin D: may be linked with impaired skin barrier comfort and overall skin resilience.
B vitamins (especially B2, B3, B6, and biotin): can be associated with dryness, irritation, or flaky areas—often around the nose, brows, or mouth.
Vitamin E: supports antioxidant protection; low intake may leave skin more prone to feeling stressed and dehydrated.
Essential fatty acids (omega-3/omega-6): not vitamins, but a frequent reason skin feels “paper-dry” despite moisturizing.

What you can do next (without overcomplicating it)

Start with a barrier-first routine while you address nutrition. Use a gentle cleanser, moisturize on slightly damp skin, and seal with an occlusive if you’re flaking. If dryness is new, severe, or paired with other symptoms, consider asking a clinician about labs before adding high-dose supplements—fat-soluble vitamins (A, D, E) can accumulate.

FAQ

How can I stop my face from peeling and flaking in the winter?

Switch to a gentler cleanser, moisturize immediately after washing, and add a thicker barrier balm at night to reduce moisture loss. Also limit hot water and over-exfoliation, which can worsen winter peeling.
