WELCOME TO PRIVATE PRACTICE.

Dr. Michele Koo · Board-Certified Plastic Surgeon · 33 Years of Clinical Experience

Most people underestimate how much skin can change before procedures are ever needed.

As a board-certified plastic surgeon trained at Stanford University and Washington University in St. Louis, I have spent 33 years watching skin change through hormones, pregnancy, stress, environment, and time itself.

What I learned in practice was simple: consistent improvement often changes skin more powerfully than sporadic treatment.

That is why I created Private Practice.

As a woman, a mother, and a physician, I formulate with both biology and daily life in mind.

Every ingredient must respect skin while still doing measurable work.

I use exact concentrations of clinically proven ingredients because safety matters—but visible change matters too.

My goal is simple: help your skin improve so consistently that treatments become less urgent, less frequent, and more intentional.

Healthy skin changes everything before anything else does.

Let me help you understand what your skin needs—and leave the rest to me.

Sincerely,

NO BS SKINCARE SCIENCE
