Sunny believes skincare is more than beauty - it is a reflection of your overall health, lifestyle, and well-being. With over 14 years of experience as an esthetician and advanced training in both clinical esthetics and holistic wellness, she created Korean Skin Theory to offer a more personalized and thoughtful approach to skin health and healthy aging.

Her passion for skincare began through her own personal struggles with sensitive, reactive skin, breakouts, hyperpigmentation, and skin damage caused by aggressive treatments. Through years of education, research, and hands-on experience, Sunny developed a philosophy centered around restoring the skin rather than overcorrecting it. 

Known for her calming presence and detail-oriented approach, Sunny customizes every treatment based on each client's unique skin condition, lifestyle, environment, and long-term goals. She believes the skin tells a story, often revealing signs of internal inflammation, hormonal changes, stress, gut health concerns, environmental triggers, and daily habits that may be affecting the skin from within.

More often than not, Sunny finds that clients are using the wrong skincare products because they misunderstand their actual skin condition. Rather than simply treating surface symptoms, she focuses on identifying root causes and helping clients better understand what their skin truly needs through customized treatments, home care routines, nutrition, supplements, travel skincare, and lifestyle guidance.

One of the most rewarding parts of Sunny's work is seeing the transformation in her clients' skin after they begin making small but meaningful changes to their daily habits and routines. For Sunny, skincare is not only about achieving beautiful skin, but also helping clients feel more confident, cared for, and connected to themselves.​
