Biostimulator Treatments
Biostimulator Therapy for Collagen, Hair, and Skin Rejuvenation in Pasadena
Biostimulators are next-generation aesthetic treatments that go beyond filling or hydrating the skin—they activate your body’s own regenerative capacity to rebuild collagen, volume, and elasticity from within. At Beauty by Dr. Kay, our advanced biostimulator options are tailored to stimulate long-lasting structural improvements in the face, hair, and body.
Whether you're restoring volume with Sculptra, remodeling texture with Hyperdilute Radiesse, regenerating adipose tissue with Nanofat Renuva, or revitalizing hair follicles and skin using PRP, biostimulators create a deeper, longer-lasting transformation by encouraging your body to rebuild what time has worn away.
These regenerative therapies are ideal for patients seeking subtle, natural, and progressive results without drastic downtime or overfilled appearance.
More info:
Each biostimulator works by triggering a regenerative response:
- Sculptra uses poly-L-lactic acid to stimulate fibroblasts to produce collagen.
- Radiesse (hyperdilute) spreads calcium microspheres that enhance skin texture and firmness.
- Renuva Nanofat repopulates areas with regenerative adipose matrix, restoring soft volume and improving skin quality.
- PRP delivers concentrated platelets and growth factors to rejuvenate hair follicles or skin cells, enhancing healing and elasticity.
Frequently Asked Questions
Biostimulators are injectable or cellular therapies that activate the body’s natural production of collagen, fat, or growth factors. They restore structure, elasticity, and density to aging or damaged tissues over time.
Unlike traditional fillers that add immediate volume, biostimulators work gradually by encouraging your body to regenerate its own tissue—resulting in natural, long-lasting improvements in skin and facial structure.
Common areas include the cheeks, temples, jawline, neck, hands, scalp (for hair), and under-eye hollows. Each product has specific applications depending on the tissue type.
Results build gradually over 4–12 weeks and can last 1 to 2 years or more depending on the product used and your body's collagen response.
Yes. Dr. Kay often designs custom protocols that stack therapies like Sculptra + PRP or Hyperdilute Radiesse + Renuva to target both structure and surface rejuvenation.

What our Patients Say About Us
“I’ve been going to Dr. Kay for five years, and the results have been truly life-changing. From fillers (under-eye, jawline, cheeks, lips, temples, chin) to PRP for my scalp and breast augmentation scars, every treatment has been natural, subtle, and customized to my face. As an actress, it's essential my expressions stay intact—at 33, people are shocked I’ve had work done. Dr. Kay is truly the best—her techniques, precision, and global expertise set the standard. Yes, she may be more expensive, but it's worth every penny when it’s your face. I’ve never had to dissolve anything, and my confidence has never been higher. 💖💖”

“Dr. Kay is the absolute best, and her staff is always so warm and welcoming. I always have a great experience at every appointment. I love that Dr. Kay offers specials each month, and her Stay with Kay program is a no brainer especially if you are dedicated to routine Botox and overall maintenance. Her skincare products are also awesome. I use the Vit. C Serum, Deep Blue Hydration., and Neck Firming Therapy cream. Dr. Kay's work is flawless, and I always get so many compliments after my visits with her. She is such a sweetheart and so is her manager Carmen and the rest of the staff. Highly recommend!!”

“Dr. Kay is truly exceptional! I’ve been a follower on Instagram, admiring her work, and I finally had the opportunity to experience it firsthand. Her products and services are top-notch. Personally, I underwent a nose job as a teen, and unfortunately, the initial results left me feeling insecure. Thanks to Dr. Kay’s renowned liquid Rhinoplasty, she transformed my nose into my dream look in just 20 minutes! I’m incredibly thrilled with the results, and her supportive staff only adds to the positive experience. My confidence has seen a significant boost. Without a doubt, I highly recommend Dr. Kay!”

“I participated in a Radiesse study for lower face balancing for Dr. Kay’s Modern Aesthetic Theory.
I always appreciate Dr. Kay’s direct communication, professionalism and expertise. I also had her address some changes in under eye filler that I had and wasn’t happy with. You never want to go just anywhere with regard to aesthetics and under eyes. I did wait a while longer than I expected to be seen, however, overall I’m happy with the results. Subtle, and natural.”

“I have been treated by Dr. Kay for the last 8 months doing a Sculptra study.
I had previously been using fillers to help with what I thought was volume loss throughout my face. With this one Sculptra study, Dr. Kay has essentially given me a face lift without using any fillers or adding volume to my face. I trust Dr. Kay and her staff to keep me looking my best without changing my overall look. I’m incredibly happy with my services!.”
