HArmonyCA - What is it?

HarmonyCA is a hybrid injection product consisting of a combination of hyaluronic acid and calcium hydroxyapatite (CaHA). Hyaluronic acid is a natural substance that moisturizes and increases the volume of the skin. CaHA is a stimulating material that stimulates the production of the body's own collagen and thus leads to a long-lasting tightening of the skin.

The effect of HarmonyCA is based on the synergistic combination of these two ingredients. The hyaluronic acid provides immediate results by moisturizing the skin and restoring volume. At the same time, CaHA stimulates the body's own collagen production, which leads to a gradual improvement in skin structure and firmness.

Through this unique combination, HarmonyCA provides an effective solution for facial rejuvenation by achieving both immediate and long-lasting results. It can be used to reduce wrinkles, restore volume to the face and improve contours

Treatment procedure

The HarmonyCA treatment process begins with a thorough consultation and examination. Once the treatment goals have been determined, HarmonyCA injections are carried out in the desired areas of the face. The treatment is generally painless, but can be supplemented with local anesthesia if required. Mild swelling or redness may occur after the treatment, but this usually subsides within a few days. The results are immediately visible and improve over time as the CaHA stimulates collagen production. Regular top-up treatments may be recommended to maintain results.



The duration of the effect of a HarmonyCA treatment can vary from person to person. However, the effect usually lasts for several months to a year. The hyaluronic acid component provides immediate results that are most visible in the first few weeks after treatment. The CaHA stimulates the body's own collagen production, which leads to a gradual improvement in skin structure and firmness. This effect can last over a longer period of time, helping the results to remain visible for longer. To maintain optimal results, regular refresher treatments may be recommended. Please consult Dr. Conrad to determine the individual durability of the effect.


When will the result be visible?

Results can be seen immediately after the procedure and improve over the following 12 weeks.

Is a HArmonyCA injection painful?

HarmonyCA injections can be slightly painful as they are injections. However, a local anaesthetic or cooling technique is usually used to minimize discomfort. However, everyone feels pain differently, so the experience can vary from person to person. However, most patients find the treatment to be painless and very tolerable.


Rules of conduct
  • Do not smoke for at least 4 hours after treatment
  • Make-up only from the following day
  • No intensive competitive sport, sun, sauna or solarium for at least 24 hours
Which combination treatments are possible?

During a HarmonyCA treatment, various combination treatments can be carried out to achieve optimal results. Here are some possible options:

  • Botulinum toxin (Botox): The combination of HarmonyCA with botulinum toxin can help treat volume loss as well as fine lines and wrinkles. While HarmonyCA restores volume, botulinum toxin relaxes the muscles and thus reduces the formation of new wrinkles.
  • Microneedling with chemical peel: Microneedling can be used in combination with HarmonyCA to further improve skin texture. These treatments stimulate collagen production and can help to reduce pigmentation spots, scars or fine lines.
  • Thread lifting: The use of PDO threads in conjunction with HarmonyCA can have a synergistic effect. The threads provide additional support and tightening of the skin, while HarmonyCA restores volume.

It is important to note that each case is individual and the exact course of treatment depends on various factors. A thorough consultation is therefore essential to determine the best treatment plan for you.


Before / After


David Conrad, MD

M. Sc. Aesthetic Medicine

After his time at the Freiburg University Clinic and a private aesthetic clinic near Zurich, Dr. Conrad rounded off his further training as a highly specialized doctor in aesthetic consultations at the laser clinic next to Prof. Dr. Raulin and at the Aesthetics and Skin Centre in Karlsruhe.

At the same time, he deepened his knowledge in the field of thread lifting and minimally invasive aesthetic treatments with a Master of Science in London.


Our intention? Simple!

To demystify the hype and hysteria of the skincare industry.


Mr. Conrad is very empathetic, friendly & authentic! A really great speaker with impressive expertise in the field of aesthetic medicine, hyaluron and Botox! We especially appreciated Dr. Conrad's openness and honesty! A clear recommendation

Thank you for a unique, absolutely natural result.

Dr. Conrad was recommended to me by my best friend because I have been suffering from acne scars on my cheeks for a long time. He took his time and screened my skin. Together we decided to use professional microneedling together with a skin booster to correct the scars and the result is simply brilliant! Thank you so much again!
