Med Spa Claremont FAQs

Where is your Claremont med spa located?

The Treatment Skin Boutique in Claremont is at 250 W 1st St, Suite 146, in the Claremont Village, close to local shops and restaurants. Street parking is free and plentiful. We’re a quick drive from Upland, La Verne, Pomona, Montclair, and Rancho Cucamonga.

The Treatment Skin Boutique offers Botox, Dysport, Xeomin, and other wrinkle relaxers at our Claremont Village location. Our PAs and nurses treat forehead lines, frown lines, crow’s feet, and more, using a natural approach that keeps your expressions intact. You’ll look refreshed, not frozen

Masseter Botox is injected into the jaw muscle to relax it, which can slim a square or overly prominent jawline and ease jaw tension from teeth grinding or clenching. It’s a completely different application than Nefertiti Botox, that one lifts the jawline and neck, this one relaxes the muscle underneath it, so which one (or both) makes sense depends on what you’re actually trying to fix.

For injectables and lasers or your first visit with a new provider, yes. A consultation lets us look at your skin, talk through what you want, and map out a plan that fits your goals, timeline, and budget. For facials and peels, you can book directly.

It depends on the area you’re treating, the product, and how much you need. Botox is priced per unit, and filler is priced per syringe. The best way to get an accurate number is a consultation, where your provider will look at your goals and give you a real quote before any treatment begins.

We carry both Juvederm and Restylane at every location, and the honest answer is neither brand is universally “better,” they’re formulated a little differently, which makes each one suited to certain areas and textures. Your injector will recommend the brand that fits the area you’re treating and the look you’re going for, rather than defaulting to one across the board.

PDGF (platelet-derived growth factor) microneedling pairs traditional microneedling with a concentrated growth factor serum to boost collagen production and speed up healing. It’s one of our most-booked treatments for texture, tone, and overall skin quality.

When choosing a med spa in Claremont, look for experienced providers, natural-looking results, strong patient reviews, and personalized care. A quality med spa should prioritize education, safety, and customized treatment recommendations rather than a one-size-fits-all approach. At The Treatment Skin Boutique, we are known for our boutique experience, expert providers, and treatments designed to enhance your confidence while still looking like yourself.

Yes. Our Claremont injectors offer lip filler by Juvederm and Restylane for added volume, better shape and definition, or simple hydration. We focus on balanced, natural-looking lips that fit your face, so you won’t end up looking overfilled. Your injector will walk you through options during your consultation and recommend the product that fits your goals.

Look for a med spa that puts balance and subtlety ahead of volume. At The Treatment Skin Boutique, our injectors customize every filler treatment to your facial structure, so the results enhance your features without changing what makes you look like you. Founded by Erin Jensen, PA-C, our Claremont flagship has built its reputation on results that look refreshed and are never overdone.

Our Claremont team includes founder Erin Jensen, PA-C, along with Annie Marciano, PA-C, Lindsey Hoffmann, PA-C, Angela Segovia, PA-C, Sarah Searles, PA-C, and Morgan Kostolefsky, RN. Every injector is trained in our signature natural-looking approach, and many of our clients have been seeing the same provider for years.

Yes. Our Claremont Skin Boutique offers BBL (BroadBand Light), Moxi laser, and microneedling, including PRFM and PDGF microneedling. All of these treatments are performed by our nurses Heather Girardot, RN and Amanda Raygoza, RN as well as PAs. They can target texture, sun damage, pigmentation, redness, and fine lines, and your provider will build a treatment plan around your skin goals.

The Treatment Skin Boutique in Claremont offers:

  • Injectables, including Botox, Dysport, dermal fillers, lip filler, collagen stimulators & sclerotherapy.
  • Laser and light treatments like BBL and Moxi
  • Microneedling with PRFM and PDGF as well as hair restoration using PRFM
