This lip serum from Anua is formulated to provide long-lasting hydration for dry and cracked lips. The product contains salmon DNA, also referred to as PDRN, which is a ingredient used in Korean skincare to support moisture retention and skin repair. Hyaluronic acid is included to help attract and hold water within the lip surface, while collagen contributes to maintaining a smooth and pliable texture. The serum has a non-sticky finish, making it suitable for everyday wear under lip products or as an overnight treatment. Its lightweight consistency absorbs without leaving a heavy film, which can be beneficial for those who prefer a comfortable, barely-there feel. The formula is designed to address dry lips resulting from environmental factors, indoor heating, or frequent exposure to drying climates. It may also be used by individuals with chapped or flaking lips seeking a moisturizing step in their lip care routine. This product is manufactured in South Korea as part of Anua’s skincare lineup, which emphasizes gentle and effective formulations. The 0.33 fl.oz size allows for easy carrying and application throughout the day. Regular use may help maintain a softer lip surface and reduce the appearance of roughness. As with any cosmetic product, individual results can vary depending on the condition of the lips and frequency of application. The ingredients do not typically include common irritants such as artificial fragrances or alcohol, but users with specific sensitivities should review the full ingredient list before use. This serum can be incorporated into a daily lip care regimen for maintaining moisture balance without tackiness.
