Abstract

Objective: Photosensitivity, commonly known as sun allergy, is a type of delayed hypersensitivity reaction that occurs when specific exogenous substances come into contact with the skin and the area is subsequently exposed to ultraviolet or visible light. Photosensitivity is accompanied by erythema, redness, burning sensation, pruritus, and pain, and in severe cases vesicles or blisters may develop. To minimize these reactions, it is necessary to reduce contact with the causative substances and limit exposure to ultraviolet and visible light, but these measures have limitations in achieving fundamental improvement of symptoms. Case Report: This case involved a Korean woman in her 40s who presented with symptoms such as erythema and redness due to photosensitivity. After the onset of photosensitivity, she experienced discomfort in daily life, including limitations in daytime activities, along with recurrent exacerbations of her symptoms. Therefore, Ortho-Cellular Nutrition Therapy (OCNT) was applied using anthocyanins, omega-3 fatty acids, glycyrrhizin, vitamin D, methylsulfonylmethane (MSM), minerals, hyaluronic acid, and plant-based oils. As a result, overall symptoms such as erythema and redness improved, and she was able to carry out daytime activities without difficulty, with a consequent improvement in quality of life. Conclusion: Because this case involved a single patient, there are limitations in applying the same OCNT regimen to other patients with photosensitivity. However, it is considered meaningful that OCNT improved the symptoms of photosensitivity and the associated discomfort.
