HArmonyCA

HArmonyCA

Looking to lift, refresh and restore your skin? HArmonyCa is the latest innovation in injectables, designed to give you the best of both worlds. This hybrid filler combines hyaluronic acid, which provides an instant boost of volume and hydration, with calcium hydroxyapatite (CaHA), which works over time to stimulate your skin’s natural collagen for long-term lift and tightening. This treatment is the perfect choice for tackling mid-face hollowness, sagging, and areas where skin loses firmness with age. You’ll notice an immediate smoothing and lifting effect, while the collagen-stimulating benefits continue to work beneath the surface, strengthening and rejuvenating your skin for results that look natural and last longer. With treatments taking just 15–30 minutes and no downtime, HArmonyCa is a simple yet powerful way to achieve fresher, firmer, more youthful-looking skin. Learn more

Booking and Payment

This treatment is available as a single session or as part of a course for optimal results. We offer flexible payment options, including Klarna and Clearpay (pay in 3 installments). All bookings are valid for 12 months from the date of purchase.

How Many Sessions will I need?

Most patients require just one treatment session of HArmonyCa to achieve visible improvement. Your Cavendish Clinic doctor will create a personalised treatment plan depending on your goals and the degree of volume loss or skin laxity. In some cases, a review or follow-up session may be advised to refine results.

How long do the results last?

You’ll see an immediate lifting and volumising effect from the hyaluronic acid component, with further improvements developing over 1-2 months as collagen stimulation takes effect. Results typically last 18-24 months, significantly longer than many standard dermal fillers.

Procedure Time

30 to 60 minutes, including consultation and application of numbing cream.

Aftercare Advice

Following treatment, you may experience mild swelling, redness, or bruising at the injection site, which usually settles within a few days. To ensure the best results, avoid alcohol, strenuous exercise, hot baths, and saunas for 24 hours. Do not expose the treated area to excessive sun or sunbeds for at least one week, and avoid applying makeup for 12 hours. Keep the skin clean, hydrated, and protected with SPF daily.

Disclaimer
HArmonyCa is a prescription-only injectable treatment and may not be suitable for everyone. It is not recommended during pregnancy, breastfeeding, or in patients with certain medical conditions. A full, doctor-led consultation is required to assess suitability and design a personalised treatment plan. Individual results vary depending on age, skin quality, and lifestyle.

The hydra facial was so deep and really cleaned my pores and super hydrated my face leaving me with a red carpet worthy glow. My skin also felt more plump and fine lines looked reduced. Would recommend this treatment."
