Can Vitamin D Help Rosacea?

Author: JM S Morales

Yes, vitamin D supplements can help with managing rosacea.

New studies show that vitamin D, particularly vitamin D3 can provide relief from skin inflammatory skin ailments such as rosacea.

Rosacea, Cathelicidin and Vitamin D

What is the link between vitamin D and rosacea? It can all be explained by cathelicidin dysfunction. Normally, our bodies produce antimicrobial peptides or AMPs, which protect our skin against infection. Cathelicidin is an antimicrobial peptide that is found in the skin and it was found that individuals who do not produce or process cathelicidin properly are more likely to have rosacea. One of the ways with which cathelicidin can be regulated is through the intake of vitamin D3 supplements, which was found to regulate cathelicidin in the skin, and therefore treat or manage inflammatory skin diseases such as rosacea.

What is Rosacea?

Rosacea is a disease that is characterized by the frequent redness or flushing of the face composed of small red bumps, which may or may not contain pus, as well as small red lines or blood vessels that appear under the skin. Other symptoms of rosacea include a swollen red nose, having thick skin on areas such as the forehead, chin and cheeks, as well as red, dry and itchy eyes, which is called ocular rosacea.

When rosacea advances, this is known as rhinophyma, which is essentially the enlargement of oil glands in the skin, thus making the nose and cheeks appear larger and puffier.

Vitamin D

According to the American Academy of Dermatology, the best sources of vitamin D are vitamin D rich food and beverages, as well as dietary supplements. And although the sun is a rich and abundant source of vitamin D, the American Academy of Dermatology cautions against overexposure to the sun and indoor sunlight sources such as tanning devices, as these are known causes of skin cancer. Thus, it is better to obtain vitamin D from food and supplement sources.
