This Matte Sun Stick was developed with Ramón @glowbyramon, an influencer and cosmetic chemist, as the director. It was created after an extensive collaboration by meticulously going through all the processes that fall under BOJ's brand philosophy of Modern Hanbang skin care. Most sun sticks are focused on use for outdoor activities, but we wanted to bring out the usefulness of sun sticks in our daily lives in bustling cities as well. To get listed SPF and PA protection level, sunscreen should be reapplied every 2-3 hours, but thats not easy to do all of the time. So, we developed a sun stick with a matte formula that doesn't get clumpy and doesn't feel sticky or greasy even when reapplied several times over makeup. How to use Apply to areas that need sun protection, such as the face and body. Reapply every 2-3 hours. *When using new products, a patch test is recommended before use. *Due to its solid formula, excessive pressure may cause the product to separate from the container
