About Us

Full Service MedSpa in Orange County


At Before and After Skincare Clinic we believe in offering the best non-surgical improvements to help you look your best so that you’ll have the confidence to reach for your dreams. We invest in the latest technological advances available in anti-aging & overall skin rejuvenation. Whether it’s toning, tightening or improving complexion, our medical spa offers top-of-the-line laser, radio-frequency & ultrasound treatments that render excellent results with less down time than ever before. Most of our staff has been trained in South Korea, a global leader in the skincare industry where a preventative approach is the norm rather than waiting until more drastic surgical measures are required. We are best known for our Korean facial that utilizes a special hand-technique with acupressure to improve circulation. Some say it’s the best Korean facial in Orange County! Our nurse specializes in injectables that help sculpt and lift in a subtle way, taking years off your face while maintaining a natural look.

Let us help you slow down the aging process so that you can put your best face & body forward with confidence. Don’t let your bad skin turn into self-imposed boundaries that stop you from living the life you deserve.

Our Staff

Dr. Kevin Do

Medical Doctor & Owner (speaks English, Vietnamese & conversational French & Spanish) Dr. Do graduated from University of Southern California and has been practicing medicine for over 20 years. After working at USC County hospital and later with hospice patients, Dr. Do finds the cosmetic industry more uplifting and hopeful. Watching his patients feel better about themselves keeps him motivated.

Supervisor (speaks Korean and English) Growing up in Korea, good skin care was instilled in Sarah Lee at a young age. Feeling inspired to bring the Korean preventative approach to the US, Sarah opened Before and After Skincare Clinic 17 years ago. Sarah’s true passion is watching clients transform into their best selves…literally Before and After! Whether it’s seeing acne scars dissipate or a youthful glow restored, Sarah’s soul is fed when she sees her clients walk away with more confidence. A believer of nourishing the soul as well as the skin, Sarah supports community events that enhance self-awareness, empowerment and confidence. When Sarah is not transforming skin, you will find her with family or on the golf course (with her sun protection of course!).


Registered Nurse (speaks Korean and English) Karen’s extensive background in the medical field make Karen a valuable asset to Before and After. Karen says that staying on the cutting edge of technology is one of the things she loves about her job. If she’s not getting trained on a new machine, you may find Karen volunteering at her church or taking day trips with her family. With a heart for people, Karen was born to be a nurse.


Esthetician (speaks Korean and English) Born in Korea, Jinny’s skin care roots run deep. Jinny understands that the South Korean skin routine that is so popular now is more than just a rage…it’s a lifestyle! Jinny believes that skin care is a vital part of healthy self-care which leads to a happy life. Jinny’s authentic and warm demeanor make her a pleasure to be around. On weekends Jinny enjoys spending time with her family and going on adventures.

Business Consultant (speaks Spanish and English) Karina’s warm personality is a breath of fresh air! After years of working at Before and After as the receptionist, Karina now acts a consultant, providing guidance and oversight to the operations. She’s like family to us so we can’t get rid of her! A lover of the beauty industry, Karina says she has learned so much about Korean skin care, culture and food since working at Before and After.
