CATEGORY 64 AUSTRALASIAN DENTIST CLINICAL The Science of Skin Boosters: How Injectable Treatments enhance Skin Quality Dr Giulia D’Anna By Dr Giulia D’Anna, BDSc, MRACDS, FIADFE, Grad. Dip. Derm. Ther Cert IV TAE, Grad. Cert laser giulia@dermaldistinction.com.au In the ever-evolving field of aesthetic medicine, skin boosters, also called biorevitalisation has emerged as a key treatment for restoring hydration, elasticity, and overall skin health. Unlike traditional dermal fillers, which are designed to add volume and structure to the face, Skinbooster treatments work by enhancing skin quality at a cellular level. Among the various biorevitalising agents available, hyaluronic acid (HA) has become the gold standard due to its powerful hydrating properties and ability to integrate seamlessly into the skin’s extracellular matrix (ECM). Why Hyaluronic Acid? Hyaluronic acid is a naturally occurring substance in the skin, responsible for maintaining moisture balance and structural integrity. It has a remarkable ability to bind water, keeping skin plump and hydrated. When used in injectable treatments, HA not only replenishes moisture but also stimulates collagen production, improving skin texture, firmness, and elasticity over time. The effectiveness of HA in Skinboosters lies in its viscoelastic properties—it must be fluid enough to spread evenly through the dermal tissue without creating bulk or irregularities. Unlike volumising dermal fillers, which are injected at deeper levels, biorevitalisation requires low-viscosity HA formulations that can be delivered into superficial skin layers with minimal trauma. This allows the HA to disperse naturally, enhancing hydration and promoting longterm skin rejuvenation. The Role of Cross-Linking in HA Skinboosters Hyaluronic acid injectables come in two primary forms: u Non-Cross-Linked (NCL) HA – A highly fluid, short-lived form that provides immediate hydration but breaks down quickly due to enzymatic degradation. u Cross-Linked (CL) HA – A more stable form that is chemically modified to resist natural breakdown, allowing for longer-lasting results and sustained collagen stimulation. Both formulations have their place in aesthetic medicine, with non-cross linked HA being ideal for quick hydration boosts and cross linked HA providing extended benefits over several months. HA concentrations in biorevitalisation treatments typically range from 8mg/ml to 20mg/ml, with lower concentrations suitable for younger skin and higher concentrations better suited for ageing, photo-damaged skin. To further enhance its longevity, HA is often combined with antioxidants such as mannitol and glycerol, which help neutralise free radicals and reduce premature degradation, and improve hydration values for the skin. These formulations ensure that the benefits of Skinbooster treatments are prolonged and more effective over time. Who Can Benefit from SkinBoosters? Biorevitalisation is not just for mature skin. While it is highly effective in reducing signs of ageing, it is also an excellent treatment for younger patients looking to maintain skin health and delay the onset of fine lines and dehydration. Common Treatment Areas u Overall Face – Improves overall skin quality, hydration, and texture. u Smokers lines – Targets skin laxity and loss of collagen architecture in delicate areas. u Lateral and medial cheek – Reverses signs of ageing caused by photoexposure and volume loss. Unlike traditional dermal fillers, where immediate results are visible, the effects of biorevitalisation take time to develop. Patients often notice a glowing complexion
