Ten-step skincare routines with sheet masks, hydrating essences, and elegant sunscreen formulations; plump, clear complexions achieved through effective, gloriously textured formulas—K-beauty has swept across the skincare aficionado spectrum like nothing else. The K-beauty market is forecast to reach $18.32 billion by 2030 with a CAGR of 9.2%. According to Cult Beauty, the number of mentions for “glass skin” across  Instagram, TikTok, and Google reached 3.3 billion mentions in 2023. A pioneer of the genre in the US market is Alicia Yoon, founder of Peach & Lily and Peach Slices.Peach & Lily is not only the name of the e-commerce platform Yoon launched in the 2010s, bringing K-beauty brands like Banila Co, May Coop, and Saturday Skin stateside, but also the skincare brand debuted together with its sister brand Peach Slices in 2018. Five years in the business and the powerhouse duo has reached $100 million in net sales. Both brands are distributed DTC and at Ulta; Peach Slices also counts Walmart and CVS Pharmacy as stockists.“The customer is always the most important, which, for us, translates into the product being the most important thing. We are relentless about creating the most efficacious, innovative products that truly transform and deliver results,” Yoon tells BeautyMatter. “We weren't chasing space in stores. We weren't chasing growth. It was this relentless focus on the product, and, in turn, that led to really high customer loyalty and  accelerated growth.”How did Yoon turn a bootstrapped business into a multimillion-dollar enterprise?
