Hello. I’m Lee Hong-seon, a board-certified dermatologist with 17 years of experience and the director of Mind Dermatology, where we focus on improving the essence of your skin with care. Those who visit a dermatologist often come with a wealth of information and concerns. Lately, the hottest topics in my clinic have undoubtedly been the Hongdae Skin Booster treatments, Litou and Rejuran. “I’ve been getting Rejuran because I heard it’s good, but I hear Litwo is all the rage these days?” “I hear Litwo is trending these days—how painful is it?” The questions vary, but the core concern is always the same: what will truly work for my skin? Today, I’ve summarized the fundamental differences between these two treatments, along with the advice I always give my patients in the clinic. Please bear with me for a moment :).......
