Aim: Lip care cosmetics products are any external preparation used by people to prevent drying, chapping, dullness, and beautification of lips. This study aimed to review the literature on allergic reactions induced by different types of lip care cosmetic products. Methods: A literature search was performed in PubMed from inception to June 2022. The study included articles published in English and available in full text. References of illegible articles were searched. Studies describing any patient who developed allergic contact dermatitis after the application of lip care cosmetic products were included. Results: A total of 47 reports consisting of 58 individuals experienced allergic reactions to lip care products. Several lip care cosmetics products, such as lipsticks, lip balms, lip salve, lip gloss, lip liner, and lip plumper, were found to be associated with allergic reactions. The most common ingredients that caused the allergic contact dermatitis were castor oil, benzophenone-3, gallate, wax, and colophony. Conclusions: Lip care cosmetics products contain several components that have been associated with allergic reactions. Awareness needs to be created among the general public and dermatologists regarding the presence of possible allergens in lip care cosmetic products.
