Why you need vitamin D for your immune system and also for healthy skin
Deficiency affects also your skin
Healthy levels of vitamin D prevent skin aging, promote healthy bone growth, possibly reduce the risk of certain cancers, and even improve mood.
Vitamin D deficiency results from lack of exposure to sunlight (from October until April in Austria), problems with vitamin D absorption and low dietary intake.Levels of Vitamin D can be checked with a free blood test prescribed by your doctor.
Vitamin D deficiency is associated with poor immune function, increased inflammation, and decreased insulin sensitivity. Hence deficiency can negatively impact the skin in a way that poor immune function weakens the skin barrier, increasing dryness and chance of infections. Increased inflammation can worsen inflammatory conditions like acne, eczema and rosacea.
Benefits of Vitamin D for Skin
1. Decreases inflammation:
The most important use of Vitamin D is its a mild-to-moderate anti-inflammatory effect, used clinically as a cream in the treatment of conditions like psoriasis, eczema, and vitiligo.
2. Protects the skin:
Vitamin D functions as a steroid, working within a cell’s nucleus to stimulate proliferation, regulate function, and potentially stabilize genes. According to some studies this has a protective effect on the skin, potentially fighting off skin cancers and autoimmune skin disease.
3. Decreases environmental damagers:
As an antioxidant vitamin D can also suppress damaging environmental oxidants that cause premature aging. Thus having ant/aging effect of the skin.
4. Normalizes cell turnover:
Some studies say vitamin D have been shown to normalize cell turnover and prevent the build-up of dead cells on the skin's surface that lead to psoriasis plaques.
