The Birch Moisturizing Sunscreen by Round Lab is a Korea's best-selling SPF that Ayan highly recommends. Ayan loves that this sunscreen doesn't leave a white cast on the face, which is a common concern with SPF products. However, Ayan does mention one drawback - the lack of English ingredients on the packaging. Ayan suggests that the brand could include a small paper inside the box with the ingredient list. Despite this minor inconvenience, Ayan took the time to research and found the ingredients to be impressive. Overall, Ayan's review is positive and helpful, showcasing the effectiveness of this sunscreen.
