Why Choose Skin Theory?
Expertise Meets Individualized Care
Here's why patients across Westchester County trust us.
Our board-certified Nurse Practitioner brings 18 years of clinical experience to every appointment — including a decade in dermatology. That background means a deeper understanding of skin, anatomy, and how treatments interact over time.
We do not rush consultations or treat every face the same. Before any treatment begins, we assess your facial anatomy, movement patterns, and goals — then build a plan specific to you. Nothing is injected until we are both confident in the approach.
Overdone results are almost always the product of too many units, placed too quickly. Our dosing philosophy is deliberately conservative — enough to soften and relax, while preserving your full range of natural expression.
Skin Theory is an intentionally small practice. You will always see the same provider, who knows your face, your history, and your goals. No rotating staff, no high-volume churn — just consistent, personalized care.
A background in dermatology changes how you see skin. Our provider understands how skin ages, how it responds to treatment, and how to plan for results that hold up over time — not just look good in the short term.
Conveniently located in Mount Kisco, NY, Skin Theory Aesthetics serves patients from Chappaqua, Armonk, Bedford, Pleasantville, Katonah, and across Westchester County looking for a trusted provider near them.
Our provider has spent nearly two decades in clinical practice — including 10 years in dermatology and 10 years in medical aesthetics.
Every appointment at Skin Theory is with the same board-certified Nurse Practitioner. No rotating staff. No surprises. Just consistent, expert care every time.

What People Are Saying
“Glowing skin starts with finding someone you can trust. I’ve loved every treatment- from chemical peels, PRP microneedling and PRP for my scalp. Erika is extremely knowledgeable and takes time to understand my needs along with the outcome I am looking for. My skin feels brighter, smoother, and healthier, and the care and attention she gives every visit is amazing. So grateful for the expertise and results from Skin Theory- truly the best experience from start to finish.”
— Christina S“I had my first ever Botox experience at Skin Theory. I felt that I was guided well and given a specific plan for my forehead lines. I didn’t feel any pressure to treat more areas on my face. I learned about how Botox works and had a better understanding of wrinkle prevention in the future . I booked a skin consult for my next visit to address acne scars and texture that concerns me. ”
