Sarah Kinsler-Holloway

Bio:

Sarah Kinsler is a licensed esthetician, educator, and founder of by Kin Aesthetics, a professional beauty brand dedicated to bringing the innovation and artistry of Korean skincare to estheticians across the United States. With a background in anthropology and years of experience in the professional skincare industry, Sarah brings a unique perspective to aesthetics—one that looks beyond trends to explore the culture, philosophy, and intention behind the way we care for skin. Her own time living in South Korea sparked an early interest in Korean beauty and ultimately helped shape Kin’s approach to education and product curation.

Through by Kin Aesthetics, Sarah works closely with Korean skincare brands, educators, and industry professionals to make advanced Korean formulations, treatment philosophies, and techniques more accessible to estheticians.

At the heart of Sarah’s work is a belief that great skincare is about more than products—it’s about education, curiosity, connection, and bringing greater intention to the way we practice aesthetics.
