I trust Farzaneh Momeni completely with my skin. She is by far the best clinical aesthetician I’ve ever known. My skin has improved dramatically since I began monthly facials with her. Her treatments are 100% results-driven so if this is what you seek, look no further. Also, the entire Team at West Dermatology are top-notch. They’re always friendly, professional, & helpful, & greet everyone with a smile. 10 Stars all around!
My new regular cosmetic dermatology office. Dr Zubair is amazing and really patient with me. He has helped me over the last year with keloid scar removal, jaw Botox, and full facial acne scar treatment (ultra clear). The office is clean and the nursing/medical assistant staff is accommodating on all levels. I will always recommend this office and Dr Zubair to friends and family.
Most professional and most impressive! The service from the physicians to office staff is superb!
I live in Orange County and drove all the way out to see Dr. Wu because a friend of mine referred him (she had amazing results from her face and neck procedure). Dr. Wu is truly an artist! He made me feel extremely comfortable during my procedure. I was anxious when I got there, but he (and his staff) have such great energy and are so very kind and gentle that you can't help but feel at ease! The office was immaculate and they adhered to covid rules (sanitizing, temp checks, masks). This is my go-to place from now on and Dr. Wu is my go-to guy! Can't wait to see my final results! Thank you Phyllis (pre-op) for being so wonderful and informative! You were so very helpful and kind! I'll definitely be back!
Leysin and the entire team at Cosmetic Laser Dermatology are fantastic. They are professional, caring and communicative. The laser treatment was comfortable, efficient and effective! I highly recommend this practice. I definitely will come back and recommend her and Cosmetic Laser Dermatology to my family and friends.
Dr. Goldman is amazing! I came here for my permanent eyeliner removal (which is not offered anywhere near me), and they are completely removed in just one session. They use a special contact lens to protect your eyes from the laser, and there are no damages to my eyelashes. The healing was also nice and smooth. They have everything you need. I live almost 3 hours away, but it was totally worth the trip. For anyone who is looking to remove their permanent makeup, this is the right place to go :)-
Dr. Butterwick is fantastic, all of her team as well. They make sure your experience is pleasant and painless as possible. My tattoo removal and my injectables look amazing. I highly recommend her for any skin treatment.
Cosmetic Laser Dermatology was recommended to me by my dermatologist. He recommended Dr. Monica Boen. I'm so glad I took his recommendation. Everyone here at Cosmetic Laser Dermatology was super nice and friendly. Very welcoming. I came here for hair removal treatment. I did 4 sessions with Dr. Boen. Dr. Boen made me feel so comfortable and at ease when I talked to her. She explained everything before she did my treatment. I loved that. She was really easy to talk to. I definitely will come back and recommend her and Cosmetic Laser Dermatology to my family and friends.
This office is awesome. My visit today was with Dr. Groff. His bed side manner is so fun and welcoming. He understood my concerns and recommended a treatment plan that I feel was reasonable. I love his staff! They take there time to make sure you understand the treatment and after care. Everyone in the office, from the front desk to the nurses in the back, are so friendly and beautiful. They are very prompt and I trust my care with CLD. I can't wait for my next visit. See you guys in a few weeks!
"Dr. Sabrina Fabi is genius! Her technique is unlike anyone, her eye is precise, and her kindness and caring manner comes from the depth of her soul. She's simply brilliant! It's no wonder people travel the country just to be treated by her."
I wish I could give them 10 stars! I had such an awesome experience for my first visit and I am referring everyone I know to this office. From the super friendly staff to the state of the art procedures, they are the cream of the crop.
“I came to participate in a research study. All of the Doctors and staff at C.L. Dermatology are very professional, warm and friendly. All our my needs were anticipated and the hospitality of this office is like a five star hotel.”

How RHA Fillers Work
Your face makes countless movements and micro-movements daily. Squinting, smiling, frowning, talking, and laughing create wrinkles and folds in areas that move repetitively. These dynamic wrinkles should be treated without creating stiffness or unnatural appearance.
RHA dermal fillers address these concerns through their unique resilience, which comes from gentle manufacturing that preserves hyaluronic acid’s natural structure. This allows the formula to stretch more easily in dynamic facial areas, resulting in natural-looking results that adapt to your skin tissues.
The fillers are injected into mid-to-deep dermis or deep dermis to superficial subcutaneous tissue to smooth facial wrinkles and folds. Because they’re very similar to your skin’s natural HA, they integrate seamlessly while providing structural support and maintaining facial vitality.
The Complete RHA Collection
RHA 2: For Dynamic Moderate Wrinkles
Designed for moderate wrinkles on the upper face, including forehead, crow’s feet, and glabella. Also ideal for subtle lip enhancement and adding volume to lip contours while maintaining natural movement.
RHA 3: For Severe Dynamic Wrinkles
Perfect for deep wrinkles and creases like nasolabial folds and vertical lip lines. Can be used for cheek augmentation, facial shape restoration, and lip augmentation with natural flexibility.
RHA 4: For Dynamic Extended Areas
Provides volume in dynamic extended areas such as cheeks and upper cheeks to correct deep skin depressions and contour the face while maintaining natural movement and expression.
RHA Redensity: For Dynamic Perioral Lines
The first RHA filler approved for both superficial and deeper injection of dynamic perioral lines. Redensity 1 treats facial lines and areas of the face, neck, chest, and hands. Redensity 2 addresses delicate under-eye skin.
Treatment Process and Results
Our board-certified dermatologists are anti-aging experts with extensive injectable training, ensuring precise filler placement as part of your customized treatment plan.
RHA fillers contain lidocaine as a local anesthetic to reduce discomfort during treatment. Patients generally tolerate procedures well, with additional topical anesthetic available for optimal comfort.
Results are visible immediately after treatment, with gradual improvement over 2-4 weeks. Because RHA products move with your face, they take longer to break down, producing results that may last up to 15 months – longer than traditional fillers.
FAQ
Good candidates are adults 22 years or older who want to correct moderate-to-severe facial wrinkles and folds around eyes, cheeks, and mouth, add volume to lips or facial areas, or enhance facial contours while maintaining natural movement and expression.

Extensive clinical studies show physician preference for RHA products due to ease of injection and immediate results. Studies demonstrate fewer touch-ups needed compared to other fillers, high patient satisfaction levels, and better long-term improvement based on 3D skin measurements.
RHA fillers should not be used in patients with severe allergies, history of hypersensitivity to local anesthetics like lidocaine, allergies to gram-positive bacterial proteins, or bleeding disorders. Our dermatologists review medical history during consultation.
