PATIENTS with acne vulgaris have significantly lower levels of serum zinc, selenium, and vitamin D compared to the general population, according to new research published in the Journal of Cosmetic Dermatology.
The case-control study involved the collection of blood samples from 100 patients over the age of 18 who have received a diagnosis of acne by a dermatologist, and 100 patients without acne.

The researchers suggested that future acne studies should assess factors such as nutritional status, sunlight exposure, and hormonal disorders.
