Abstract
Acne vulgaris (AV) represents a chronic inflammatory condition affecting pilosebaceous units, characterized by a multifactorial etiology. AV can manifest as both inflammatory and non-inflammatory skin lesions. Non-inflammatory acne is termed a comedone, which can be either closed (whiteheads) or open (blackheads). Inflammatory acne encompasses papules, pustules, nodules, and pseudocysts. The most common regions for acne occurrence are the facial region (90%), thoracic area (14%), and dorsal region (60%). In the study involving transdermal application of vitamin D cream (applied twice daily; morning and evening) in subjects with inflammatory acne due to vitamin D deficiency, 33 participants took part, comprising 8 males and 25 females. The age group most affected was 18-25 years (adolescent age), followed by a lesser impact in the 26-30 age group, and the lowest incidence observed in the late 36-45 age group. Among males, facial and thoracic regions were most affected by inflammatory acne (37.5%), while among females, the facial region showed a higher percentage of 54%, and the thoracic area was at 40%, with a minimal impact on the dorsal region (M=25%; F=8%). Reductions in inflammatory acne ranged from 100% to 10%, with substantial improvements noted in the male population, achieving 100% and 80% reduction (100% reduction: facial region 25%, thoracic area 12.5%, 80% reduction: dorsal region 25%). Similarly, the female group, with a larger sample size (25 participants), demonstrated significant reductions (100% reduction: facial region 36%, thoracic area 24%, 80% reduction: dorsal area 4%). Overall, improvements were evident in all participants, with none falling below a 30% reduction, indicating remarkable outcomes after one month of vitamin D cream use. Numerous factors contribute to the onset of inflammatory acne, with this study specifically highlighting vitamin D deficiency in the blood. Other indications include the occurrence of polycystic ovaries and reduced thyroid function in women, heightened stress, and prostate issues in men. Reduced or deficient vitamin D levels may be associated with further immune system suppression, activating the aforementioned factors. This research marks a significant stride in uncovering the manifold health benefits of vitamin D.
