Sun sensitivity can surface when certain components in cosmetics, everyday household products, and medicines interact with ultraviolet rays. The key players here are photosensitizers and photoallergens, a distinction highlighted by dermatovenereologist Anna Zhilkina, a cosmetologist at the Atlas clinic network, in an interview with Gazeta.ru.
She explained that the so called sun allergy is not a separate disease but an abnormal skin reaction to sunlight, specifically ultraviolet light. This condition tends to show up as a small, itchy rash, redness, and swelling on areas of the skin that are most exposed. A central factor in this reaction is the presence of photosensitizers, substances that heighten the skin’s sensitivity to UV radiation.
Photosensitizers can be found widely, including in many herbs and plants such as parsley, celery, yarrow, St. John’s wort, figs, buckwheat, pine nuts, and lemons. In some individuals, the skin reaction follows a delayed mechanism, meaning the photoallergen absorbs UV light and then triggers an allergic response some time after exposure.
Photoallergens often appear in sunscreens and cosmetics, and may also be present in perfumes, soaps, shampoos, and certain household cleaners. In the medical field, external pain relievers containing ketoprofen, along with certain antibiotics, tranquilizers, and antidepressants, are listed among substances that can act as photoallergens.
These insights emphasize careful product selection for people who notice unusual sun-related skin reactions. Recognizing the potential for photosensitizers in common products helps individuals reduce exposure and seek medical guidance when needed. The information underscores the importance of reading ingredient labels and understanding how everyday items may interact with sunlight to produce a reaction on the skin. The discussion also highlights that sun allergy presentations can vary in appearance and timing, reinforcing the value of consulting a healthcare professional for an accurate assessment and tailored recommendations. This awareness supports safer sun practices and informed choices about cosmetics, personal care items, and medications that may influence photosensitivity.
