Hyaluronic Acid Filler
Rejeunesse: Consistently Recognised as a Pure, Safe and Trustworthy Brand of Hyaluronic Acid Fillers
What are HA fillers?
Hyaluronic acid (HA) injection fillers are used to reduce the appearance of fine lines, wrinkles, and facial folds by creating volume in the face. HA is a naturally occurring substance popularly used in skincare treatments. Its primary function is to trap water inside the skin, providing hydration, fullness, and elasticity to the skin.1
HA diminishes as we age, the lost volume causing facial sagging and wrinkles to appear.2 Injectable HA immediately restores lost volume, softening lines and restoring definition, but also stimulates collagen production for long-term anti-aging effects;3 rejuvenating your features for a refreshed, youthful look.
The Rejeunesse range of fillers is designed to target different layers of the skin, depending on your skin's needs. From smoothing surface lines to sculpting defined contours, the RejeunesseTM range has the right formula for every layer, delivering natural looking results.
The Rejeunesse range is formulated with pure HA derived from non-animal sources and cross-linked to provide longer-lasting results of up to 12 months.* RejeunesseTM has received the CE marking by the European Commission and is trusted by dermatologists worldwide.
Structure
RejuenesseTM’s cross-linked formulation is highly resistant to shear and degradation while providing elasticity and flexibility, ensuring long-lasting structural support that adapts to natural movement.*
Purity
RejeunesseTM fillers are created using our proprietary DIAMOLD technology, resulting in a pure HA gel free of contaminants and additives. Study results show no swelling or inflammation after one year in animal tests.*
Biocompatible
RejeunesseTM HA fillers are produced from non-animal sources, resulting in minimal risk of allergic reactions. Clinical results demonstrate exceptional safety and tolerance.
How Does Hyaluronic Acid Work?
Aging leads to decreased production of HA and collagen in the skin, causing the skin to lose its viscoelastic properties and skin moisture, and therefore, wrinkle formation.¹
HA plays a key role in binding water molecules and helps skin retain and maintain moisture.²
HA is also one of the primary components of extracellular matrix that has been demonstrated to play a beneficial role in inflammatory responses.³
Due to its highly hydrophilic and anionic properties, it can attract water to swell and create volume and provide structural support.¹

DIAMOLD Technique
The Rejeunesse range is engineered with our proprietary DIAMOLD technology.
The DIAMOLD technology—a fusion of 'Dialysis' and 'Molding', produces exceptionally pure, degradation-resistant cross-linked HA.

How it works
Ultra-Purified HA
– Dialysis removes impurities (endotoxins, residual BDDE), minimizing risks of post-injection swelling or irritation
Optimized Cross-Linking
– Tightly molded HA resists degradation, providing structural support for up to 12 months*
Natural Rheology
– The gel’s viscoelasticity mimics native tissue; flexible enough for natural movement yet cohesive for precise facial contouring

Rejeunesse minimizes side effects such as inflammation, itchiness, and swelling, by containing undetectable levels of residual BDDE,* far below the industry standard of 2 pm.

Rejeunesse, molded by our proprietary technology is highly degradation resistant and delivers long-lasting results that meets or exceeds leading competitors.*
