The health of your skin, not to mention your bones and immune system, depends on vitamin A. This vitamin can be used as a topical or oral medication to treat skin disorders like psoriasis or acne. It is not effective as a treatment for eczema. Ironically, if you use too much or too little vitamin A, you may develop skin patches that look like eczema.
Definition and Treatment of Eczema
Eczema, also known as atopic dermatitis, is a chronic condition characterized by itchy and inflamed skin. It tends to be most prevalent on the arms and the back of the knees. Typically, those with eczema don't have it all of the time. Instead, there are flareups. The cause is unknown, and the primary treatment is the relief of symptoms. Your doctor may suggest that you apply a hydrocortisone ointment to combat the itching and avoid irritants like soap. You may also need prescription medications like corticosteroids, and your doctor can help you determine if this is necessary.
Vitamin A and Skin Disorders
Retinoids are a synthetic form of vitamin A that are used to treat severe acne and psoriasis. Similar to eczema, psoriasis is characterized by itchy and inflamed skin. Thick, silvery scales on the skin are another symptom of psoriasis. Topical or oral retinoids can help to treat this condition, because they regulate DNA activity in skin cells and reduce inflammation. This form of vitamin A may also help other conditions like rosacea, warts and signs of premature aging due to sun damage, but more research is necessary, according to the University of Maryland Medical Center.
Deficiency, Overdose and Skin
Vitamin A contributes to the health, texture and function of your skin. If you become deficient, you may develop skin problems, such as dryness and flaking, that are similar to eczema. You may also experience night blindness, dry eyes and diarrhea. On the other hand, taking too much vitamin A can also cause dry skin, along with headaches, fatigue, muscle pain and hair loss. The recommended dietary allowance for this vitamin is 3,000 IU for men and 2,333 IU for women, according to the University of Maryland Medical Center.
Additional Considerations
While eczema is not typically dangerous, it can affect your quality of life, and you should talk to your doctor if this is happening. She may have lifestyle remedies or other treatment suggestions. Do not use topical or oral retiniods without first seeking medical approval. The tolerable upper limit of vitamin A is 10,000 IU a day, according to the University of Maryland Medical Center. Talk to your doctor before exceeding this.
