Abstract
- Background
Vitamin A is a fat-soluble vitamin that plays an important role in skin immunity. Deficiencies in vitamin A have been linked to impaired immune response and increased susceptibility to skin infections and inflammatory skin disease.
- Results
This narrative review summarizes recent primary evidence that elucidates the role of vitamin A and its derivatives on innate immune regulators through mechanisms that promote skin immunity and sustain the skin microbiome.
- Conclusions
Adequate vitamin A status is essential for optimizing cutaneous innate immune defenses and maintaining a balanced skin microbiome to prevent inflammatory skin conditions and infections.
