SPF, or Sun Protection Factor, is important to consider when choosing a Korean sunscreen. In Korea, SPF ratings often go beyond 50, with many brands marking their SPF as 50+ instead of sharing the exact number. Chemical filters, which are common in Korean sunscreens, sink into the skin and convert UV energy into heat. This results in a weightless texture and invisible finish. Mineral filters, on the other hand, remain on the surface of the skin and physically block UV rays. Dr. Kim prefers mineral filters for hyperpigmentation and for patients who are pregnant, breastfeeding, or undergoing fertility treatments.
Korean sunscreens utilize the PA rating system to measure protection from UVA rays. The PA system ranges from PA+ to PA+++, with PA+++ offering the highest level of UVA protection. In the U.S., there isn’t a standardized system like this for UVA protection, but instead, it is indicated under the term “broad-spectrum” to show coverage against both UVA and UVB rays. It may be unclear what level of protection this offers compared to the PA system. It is important to consider your skin type when choosing a Korean sunscreen, as some textures may be more hydrating and suited for dry skin, while others may be more lightweight and suitable for oily or acne-prone skin.
Dr. Claire Chang, a board-certified dermatologist at Union Square Laser Dermatology in New York City, recommends using at least SPF 30, which is also recommended by the American Academy of Dermatology. She explains that while the SPF rating system is the same in Korea and the U.S., Korean sunscreens often go beyond SPF 50. Dr. David Kim, a board-certified dermatologist and founder of the skincare brand Lifesaver, prefers mineral filters in Korean sunscreens for patients with specific skin conditions, as they remain on the surface of the skin and physically block UV rays.
It is essential to understand the differences between chemical and mineral filters when choosing a Korean sunscreen. Chemical filters are commonly used in Korean sunscreens and sink into the skin to convert UV energy into heat, providing a weightless texture and invisible finish. Mineral filters, on the other hand, remain on the surface of the skin and physically block UV rays. Dr. Kim recommends mineral filters for patients with hyperpigmentation or specific skin conditions. Texture is also important to consider when selecting a Korean sunscreen, as some may be more hydrating for dry skin while others may be more lightweight for oily or acne-prone skin.
Dr. Claire Chang and Dr. David Kim are experts in the field of dermatology and skincare. Dr. Chang is a board-certified dermatologist at Union Square Laser Dermatology in New York City, while Dr. Kim is a board-certified dermatologist and the founder of the skincare brand Lifesaver. They both emphasize the importance of SPF protection and understanding the differences between chemical and mineral filters in Korean sunscreens. Dr. Kim prefers mineral filters for specific skin conditions, and Dr. Chang recommends using at least SPF 30 for adequate protection against harmful UV rays. When choosing a Korean sunscreen, it is important to consider the SPF level, the type of filters used, and the texture that best suits your skin type.
