The active ingredients in sunscreen products are ultraviolet (UV) filters, many of which are known potential allergens. The use of sunscreen in younger children and individuals with sensitive skin requires special attention, since absorption and allergen sensitization are of concern.
This study aims to evaluate the ultraviolet filters in sunscreen products labeled specifically for "kids" or as "sensitive/hypoallergenic" and compare these to general sunscreen products.
From December 2017 to March 2018, the ingredient labels on commercially available sunscreen products in Bangkok, Thailand, were analyzed.
Two hundred and forty-six sunscreen products were examined. Of these, twenty products (8.1%) were marketed for "kids." Forty-one products (16.6%) were labeled as "sensitive" or "hypoallergenic." Ethylhexyl methoxycinnamate (EHMC) and benzophenone-3 (BP3) were less prevalent in products for children [(P = .004) and (P = .029), respectively]. Eighty-five percent of sunscreen products labeled for kids contained at least one chemical UV filter. There was no significant difference between BP3, butyl methoxydibenzoylmethane (BMDM), and octocrylene (OCR) in products labeled for sensitive skin compared to products with no specific labels. Moreover, methylene bis-benzotriazolyl tetramethylbutylphenol (MBBT) was more commonly found in products for sensitive skin than in nonsensitive products (P = .001).
Common allergenic UV filters were found in sunscreens labeled as sensitive and for children. Regulations for displaying these specific labels should be established for improved benefits and safety to allergy-prone skin.
防晒产品中的活性成分是紫外线（UV）过滤剂，其中许多是已知的潜在过敏原。在年幼儿童和皮肤敏感的个体中使用防晒霜需要特别关注，因为吸收和过敏原致敏是令人担忧的问题。
本研究旨在评估专门标注为“儿童”或“敏感/低敏”的防晒产品中的紫外线过滤剂，并将其与普通防晒产品进行比较。
2017年12月至2018年3月，对泰国曼谷市售防晒产品的成分标签进行了分析。
共检查了246种防晒产品。其中，20种产品（8.1%）面向“儿童”销售。41种产品（16.6%）标注为“敏感”或“低敏”。对甲氧基肉桂酸乙基己酯（EHMC）和二苯甲酮-3（BP3）在儿童产品中的含量较低[分别为（P = 0.004）和（P = 0.029）]。85%标注为儿童使用的防晒产品含有至少一种化学紫外线过滤剂。与无特定标签的产品相比，标注为敏感皮肤的产品中BP3、丁基甲氧基二苯甲酰甲烷（BMDM）和奥克立林（OCR）没有显著差异。此外，亚甲基双-苯并三唑基四甲基丁基酚（MBBT）在敏感皮肤产品中比在非敏感产品中更常见（P = 0.001）。
在标注为敏感和儿童使用的防晒霜中发现了常见的致敏紫外线过滤剂。应制定展示这些特定标签的规定，以提高对易过敏皮肤的益处和安全性。
