At the Apul Parikh Clinic, we are proud to share an exciting development in non-surgical aesthetic treatment. Dr Apul Parikh, a leading expert in aesthetic injectables and internationally respected trainer, has authored a pioneering study on the use of diluted HArmonyCa™ for neck rejuvenation, marking the first published case series of its kind.
This study not only reflects Dr Parikh’s dedication to clinical research and safe innovation, but also opens up a new, evidence-based treatment pathway for patients seeking natural, visible improvement in the neck area; an area historically difficult to treat with injectables alone.
While facial rejuvenation treatments are widely popular, the neck is increasingly becoming an area of concern for patients. The skin on the neck is thinner, more delicate, and often shows signs of ageing, such as creases, laxity, and horizontal lines, earlier than the face. For many, it can betray age even when the face appears smooth and refreshed.
However, non-surgical options for treating the neck have traditionally been limited, especially when it comes to injectable treatments. Many dermal fillers are not considered suitable due to the delicate anatomy and risk of visible product or irregularities. That’s what makes Dr Parikh’s work so significant; it suggests a way forward using an innovative, carefully diluted biostimulatory filler.
The case series involved two female patients seeking treatment for transverse neck lines, those horizontal creases that can deepen with age and repetitive motion. Dr Parikh used a pioneering technique with HArmonyCa™ with saline, allowing for a softer, more diffuse application suited to the neck’s delicate tissue.
The results were assessed using two widely accepted, validated scales:
The outcomes were impressive:
This significant case series offers the first clinical insight into the use of dilute HArmonyCa™ in the neck and sets the stage for larger-scale research with longer-term follow-up.
This isn’t just an incremental advance, it’s a meaningful step forward for aesthetic medicine. Until now, practitioners have had to rely on anecdotal evidence or off-label use without clinical data to support the effectiveness of injectables in the neck. Dr Parikh’s work begins to change that.
By carefully documenting his method, patient outcomes, and safety data, Dr Parikh is helping to build a more evidence-based foundation for aesthetic treatment in an area of growing patient demand. For patients, this means greater confidence, improved treatment outcomes, and the reassurance that procedures are backed by both experience and data.
It also reinforces the idea that true innovation in aesthetics isn’t just about trends, it’s about progress built on science, safety, and transparency.
HArmonyCa™ is an advanced injectable that combines two clinically proven ingredients: hyaluronic acid (HA), which hydrates and smooths the skin, and calcium hydroxyapatite (CaHA), which stimulates the production of collagen. The product offers both immediate lifting and long-term structural improvement, making it a unique hybrid filler.
While its application in the mid-face and jawline has been widely adopted, the use of HArmonyCa™ in the neck has remained largely unexplored until now. Dr Parikh’s case series explores what happens when the product is diluted and used with precision in this sensitive area, offering new potential for non-surgical neck rejuvenation.
