If you’ve been feeling off, tired, or just not fully yourself…

IV therapy delivers a blend of vitamins, minerals, and antioxidants directly into your bloodstream. That means your body doesn’t have to process or break anything down first.

Instead of waiting, your system can use what it needs right away.

It’s often used during busy stretches, after travel, or anytime your energy feels off and your body needs a little extra support.

A simple treatment that helps you feel more like yourself again.

Meet Sheila, an aesthetic nurse at Kintsu MedSpa ✨

Sheila started her career in bedside nursing. The work was meaningful but intense, and over time she began to feel burned out.

When she moved into aesthetics, everything changed. She could finally combine skincare, wellness, science, and medicine while actually seeing the results of her work in her patients.

She believes great aesthetic care should feel thoughtful and personal. Her approach focuses on gradual, natural results so you always look like yourself, just refreshed.

One of her favorite treatments is microneedling with PRP because it supports your skin’s natural healing and collagen production.

Outside the clinic, Sheila’s idea of a perfect reset is simple. Kombucha over ice, a face mask, and a good show.

Her goal every time you sit in her chair is to make you feel comfortable, cared for, and excited about your results.

Come say hi to Sheila next time you visit Kintsu 🤍

BTS from our facial shoot with Joy

While filming this treatment, someone asked a great question:

“What exactly is that tool doing?”

The black wand you see Joy using is designed to stimulate lymphatic movement, helping move stagnant fluid under the skin. This process supports lymphatic drainage, which can reduce puffiness, encourage detoxification, and leave the skin looking more sculpted and refreshed.

It’s just one of the many small but powerful techniques our estheticians incorporate during treatments to support healthy, glowing skin.

At Kintsu, every facial begins with a personalized skincare consultation. We take time to evaluate your skin, talk through your concerns, and create a treatment plan tailored specifically to you. That might include treatments like our Geneo Oxygen Facial, which exfoliates, oxygenates, and deeply hydrates the skin, or our Kintsu Signature Facial, designed to cleanse, exfoliate, and restore radiance while promoting circulation and relaxation.

No two faces are the same, and your skincare shouldn’t be either.

Our goal is always the same: healthy skin, thoughtful treatments, and results that look natural and refreshed.

And if you’ve had a facial with Joy, you already know why our clients love her. Her attention to detail, incredible facial massage, and calming presence make every treatment feel like the perfect reset for your skin.

Healthy skin starts with understanding your skin.

Hi everyone! I’ve noticed so many new faces here lately, so I wanted to take a moment to properly introduce myself.

I’m Dr. Shay Nicholas, the founder of Kintsu MedSpa & Wellness. Long before I entered the world of aesthetics, I felt a deep calling to care for people. That calling led me to medicine. I earned my MD from the University of Connecticut after studying Chemistry and Mathematics at Brooklyn College in New York City.

I then spent more than 20 years practicing Emergency Medicine and Critical Care, including training at Johns Hopkins. My career was dedicated to caring for patients in some of the most critical moments of their lives. That experience shaped everything about how I practice medicine today, with presence, integrity, and deep respect for the trust people place in me.

People often ask me, “How did you go from saving lives to aesthetics?”

Honestly, I used to wonder the same thing. But everything shifted after I attended a Botox gathering hosted by a close physician friend. What struck me wasn’t the treatment itself. It was the joy. Watching someone look in the mirror and feel brighter, more confident, more like themselves was powerful. I realized that helping someone feel good about themselves is also a form of healing.

My background taught me that aging is a privilege. My Caribbean upbringing taught me that joy, vitality, and self-care are part of living well at every stage of life. Aesthetic medicine became a natural extension of those beliefs.

At Kintsu, my goal has never been to dramatically change how someone looks. I’m passionate about enhancing natural beauty and helping people feel refreshed, confident, and aligned with how they want to show up in the world.

When you sit in my chair, I don’t see a treatment area. I see a whole person. Your goals, your comfort, and your safety always come first.

And when I’m not in the clinic, you’ll usually find me spending time with my three sons and our Goldendoodle, Eevee, traveling, going to concerts, watching movies, or diving into a good history book.

If you’re new here, welcome. I’m so glad you’re part of this community. 🤍

If you’ve ever wondered what a VI Peel looks like in real life, this is it.

We start with a skin assessment, talk through goals, and then carefully apply each layer of the peel based on what your skin actually needs. It’s quiet, intentional, and thoughtful.

A lot of people are surprised by how simple the appointment feels. The real magic happens in the days after, when your skin starts renewing itself.

We’ll share the full video soon, but here’s a little behind-the-scenes moment from the treatment room. 🤍

Enjoy March Specials at Kintsu MedSpa & Wellness.

This month, we’re focusing on skin tightening and long-term smoothness.

✨ 15% off Sofwave treatments and packages.
This non-invasive treatment stimulates collagen and lifts the skin naturally over time.

✨ Buy one laser hair removal package, get a second package (equal or smaller area) for free.
This is a perfect opportunity to treat multiple areas or share with someone close to you.

Both offers are available for a limited time in Berkeley and Davis.

If you’ve been considering tightening, lifting, or simplifying your routine before summer, March is a smart time to start.

Book your consultation to learn what’s right for you.
