Collagen Stimulating Filler
Collagen stimulating fillers, also known as collagen biostimulators, are advanced injectable treatments designed to restore facial structure while encouraging the body to produce new collagen. At Dr Leah Clinics, we offer innovative treatments such as Ellansé and HArmonyCa, which provide both immediate lifting and long-term skin rejuvenation.
What areas are collagen stimulating fillers used to treat?
Unlike traditional dermal fillers that mainly add volume, collagen biostimulators stimulate the skin’s natural regeneration processes. This helps improve skin firmness, elasticity, and overall facial structure, while gradually enhancing skin quality over time. These treatments are particularly effective for addressing volume loss, reduced skin firmness, and early signs of ageing, delivering subtle, natural-looking results.
Collagen stimulating fillers are commonly used to treat areas such as:
As these treatments help to restore facial support and definition. Results develop gradually as collagen production increases, with improvements in skin quality and structure continuing over several months.
At Dr Leah Clinics, treatments are carefully tailored to your facial anatomy and aesthetic goals to achieve balanced, natural-looking rejuvenation. Book a consultation to find out whether collagen biostimulators are the right treatment for you.
Before and After
"One of the key advantages of collagen biostimulators is their long-lasting results. Because the treatment stimulates your own collagen production, improvements in skin firmness and structure can continue to develop for several months after treatment and may last longer than many traditional fillers."
– Dr Leah Totton, Medical Director of Dr Leah Clinics
At Dr Leah Clinics, collagen stimulating filler treatments are tailored to your individual facial anatomy and aesthetic goals. During your consultation, our practitioners will assess your skin quality and facial structure to determine whether Ellansé, HArmonyCa, or another treatment approach is most suitable for achieving balanced, natural-looking rejuvenation.
Ellansé is a long-lasting dermal filler that not only adds volume but also stimulates collagen production for gradual, sustained results.
HArmonyCa is a hybrid injectable that combines hyaluronic acid (HA) with calcium hydroxyapatite (CaHA) to provide immediate volume along with ongoing collagen stimulation.
