How Vitamin D3 Can Help Control the Symptoms of Rosacea

According to a presentation shown at the National Rosacea Society Research, a recent study's findings show that rosacea inflammations may be the result of an allergic reaction . According to the lead investigator of the study Dr. Richard Gallo of University of California-San Diego's dermatology division, pinpointing the exact process that leads to inflammation in rosacea is important so that new medications can be developed to prevent such inflammations .

The same study further revealed that rosacea patients produce an abnormal amount of cathelicidins, a protective molecule that leads to inflammation of the skin, particularly in the form of tiny bumps and pimples that are common in rosacea patients.

Another recent study found that vitamin D3 can control the expression of cathelicidins especially in the rosacea patients . This is because vitamin D3 helps to regulate immunity and enables efficient antimicrobial defense on the skin.
