Immediate lifting effect
Collagen stimulation
Improves skin quality
Developed by Allergan, HArmonyCa is a next-generation injectable treatment that combines hyaluronic acid and calcium hydroxyapatite to provide both immediate volume restoration and long-term collagen stimulation. It is particularly effective for facial hollowness, skin laxity and age-related volume loss.
This dual-action injectable represents a significant evolution in facial rejuvenation, offering the best of both worlds: the instant gratification of a dermal filler and the progressive, long-term benefits of a collagen stimulator. At 111 Harley St., we position this advanced treatment as a cornerstone of our premium, surgeon-led approach to age-related volume loss. Unlike traditional fillers that simply add volume, HArmonyCa works to rebuild the skin’s structural integrity over time, addressing both the visible signs of ageing and the underlying causes.
Your journey begins with a comprehensive consultation to assess your facial anatomy and determine how this next-generation treatment can best restore lost volume and improve skin laxity. By integrating this sophisticated treatment into a bespoke, long-term aesthetic plan, we help you achieve a lifted, contoured, and naturally youthful appearance that reflects the high standards of our clinic.
HArmonyCa combines cross-linked hyaluronic acid for immediate lifting and contouring with calcium hydroxyapatite microspheres that stimulate fibroblasts and collagen production. This dual-action approach delivers both instant and progressive rejuvenation.
The effectiveness of this collagen-stimulating filler lies in its intelligent, two-phase design. Upon injection, the cross-linked hyaluronic acid provides an immediate lifting and contouring effect, restoring volume to hollowed areas and smoothing the appearance of fine lines. Simultaneously, the calcium hydroxyapatite microspheres begin to work beneath the surface, stimulating fibroblasts and encouraging the production of new collagen. This means that while you see an instant improvement, your skin is also actively remodelling and strengthening itself over the following weeks and months. Our expert practitioners carefully map the treatment area to ensure precise placement and optimal results, tailoring the approach to your unique facial structure.
The treatment is delivered with precision and care, supported by personalised aftercare and scheduled follow-up reviews to monitor your progress as your results develop. This comprehensive approach ensures your treatment is tailored to your individual needs and integrated into a long-term aesthetic plan, reflecting the high standards of care and clinical expertise associated with 111 Harley St.

Edward Smith31 August 2026Very Impressed With My Rhinoplasty I had been unhappy with the shape of my nose for years and finally decided to look into rhinoplasty. Choosing the right surgeon and clinic was extremely important to me, so I spent a lot of time researching before booking my consultation at 111 Harley St. The consultation was detailed and reassuring, and I appreciated the focus on achieving a result that suited my face rather than simply changing my nose. The whole process was handled professionally, from the initial consultation through to the follow-up appointments. My nose now looks much more balanced with the rest of my face, and the improvement is significant without looking artificial.Posted on Google![]()
Louise F28 August 2026I had my consultation with Anna and honestly couldn’t have been happier with the experience. She took the time to really listen to all of my concerns and went through everything with me in so much detail, including the different treatment options. I really appreciated how thorough and attentive she was, and the whole consultation felt very personal and tailored specifically to me rather than a one-size-fits-all approach. I felt really comfortable and well looked after. I’m really happy with the experience and will definitely be coming back for my treatment. Thank you so much, Anna!Posted on Google![]()

Rosie Walker17 August 2026A Wonderful Experience I decided to explore a Y Facelift after becoming increasingly unhappy with the loss of definition around my lower face. I was initially quite nervous about having facial surgery, so having a detailed consultation was really important to me. Everything was explained clearly and I felt comfortable asking lots of questions. I’m so pleased with the outcome my face looks fresher and more defined, but it still looks completely like me.Posted on Google![]()

Jessica Thomas4 August 2026The Best Decision I Made I had a facelift at 111 Harley Street. From my very first consultation, I felt completely comfortable and confident that I was in safe hands. The surgeon took the time to understand what I wanted to achieve and explained every stage of the process clearly, from the operation itself to the recovery and expected results. The care I received was outstanding from start to finish. Every member of the team was kind, professional, and incredibly supportive. They were always available to answer any questions, and I felt genuinely looked after throughout my entire journey. Now that I've fully recovered, I am absolutely delighted with the results. I look refreshed, younger, and far more confident, while still looking completely natural. The best compliment I've received is that people keep telling me I look really well without realising I've had surgery. It's exactly the subtle, natural result I was hoping for. Choosing 111 Harley Street was one of the best decisions I've made. The expertise, attention to detail, and exceptional aftercare exceeded all of my expectations. I would wholeheartedly recommend them to anyone considering a facelift.Posted on Google![]()
