What are the Most Important Vitamins and Minerals for Dry Skin?

Here are some of the vitamins and minerals that can play an important role in maintaining your skin and preventing it from drying out.

Vitamin D - Vitamin D plays a a critical role for many aspects of your body's health, including your skin. It is important for skin barrier function and skin cell growth, as well as maintaining the skin immune system, which acts as a first line of defense against harmful pathogens. Low levels of vitamin D are linked to dry skin and certain skin conditions.

Vitamin C - Vitamin C is another crucial component of healthy skin, as it plays a role in both the production of collagen and serves as a protective antioxidant. The skin contains naturally high levels of vitamin C which may help prevent moisture loss by supporting skin barrier function. This vitamin is also found in supplements to boost the immune system.

Collagen - Collagen is one of the single most important proteins in the body, and in fact makes up the majority your skin. Taking a collagen supplement may help improve skin elasticity and hydration, potentially reducing the appearance of wrinkles and helping to maintain proper skin moisture.

Fish Oil - Fish oil contains two essential fatty acids, DHA and EPA, that are extremely important to skin health. They help make up the barrier made of fatty acids in the skin that helps lock in moisture to prevent dryness. Fish oil, or krill oil supplements, can also help reduce inflammation and protect against sun damage.

Hyaluronic Acid - Sometimes used in topical ointments, hyaluronic acid plays a key role in skin hydration and elasticity. One study found that hyaluronic acid supplements improved the skin's moisture and elasticity which reduced wrinkles and roughness.

Probiotics - Certain probiotics may not only help improve digestive health, but could also play a role in boosting skin health as well. Researchers in one study found that administering a certain type of good bacteria for the gut also boosted the skin barrier and improved skin hydration.

The Research on Vitamin Supplements for Dry Skin

Research indicates that certain vitamins and supplements, including vitamin D, vitamin C, fish oil, collagen, and even some probiotics, may help to manage and improve dry skin.

Vitamin D supplementation has been shown to reduce the severity of symptoms from certain skin conditions, specifically atopic dermatitis (AD), or eczema. Deficiencies in vitamin D have also been linked to certain skin diseases like psoriasis and acne. One study also demonstrated a relationship between vitamin D levels and skin moisture levels.

Vitamin C plays a wide variety of roles in skin health. Cell culture studies have found that vitamin C can enhance the production of barrier lipids that help form the skin's moisture barrier. The antioxidant properties of vitamin C also make it important in protecting the skin from UV damage.

The fatty acids found in fish and krill oils have widely-known applications for cosmetic and therapeutic benefits for the skin. Fish oil helped to improve the symptoms of patients suffering from psoriasis in one study, and it has also proven to help reduce skin inflammation from sun damage. Collagen has also been shown to directly benefit skin health. A study of oral collagen supplements found that they resulted in improved skin elasticity and skin hydration over a placebo.
