TEOXANE is one of the world's leading manufacturers of hyaluronic acid dermal fillers — and that expertise in HA science is the foundation of the RHA Serum. Formulated with Resilient Hyaluronic Acid (RHA®), TEOXANE's proprietary HA technology developed from their injectable filler research, this advanced serum goes beyond standard hydration to actively strengthen the skin matrix, improve elasticity, and restore a visibly brighter, more youthful complexion.
Suitable for all skin types. Visible results from 14 days.
Standard hyaluronic acid in skincare is typically fragmented or chemically modified, which limits its ability to integrate with the skin's own HA network. TEOXANE's RHA® technology preserves the natural, long-chain structure of hyaluronic acid — making it more biocompatible with the skin's own matrix and better able to support the structural integrity of the dermis. This is the same philosophy behind TEOXANE's award-winning injectable filler range, applied to topical skincare.
TEOXANE RHA Serum is specifically formulated to complement aesthetic treatments:
Apply a small amount to a freshly cleansed face and neck once or twice daily. Gently press into the skin rather than rubbing. Follow with moisturiser and SPF in the morning. For pre- and post-procedure use, follow the protocol above or as directed by your aesthetic practitioner.
TEOXANE's RHA® (Resilient Hyaluronic Acid) technology is derived from their expertise in manufacturing hyaluronic acid dermal fillers. Unlike standard HA serums that use fragmented or heavily modified hyaluronic acid, RHA® preserves the natural long-chain structure of HA — making it more biocompatible with the skin's own matrix and more effective at strengthening the dermis rather than simply hydrating the surface.
Yes — and it is specifically recommended for this purpose. Using RHA Serum for 4 weeks before filler treatments helps strengthen the skin matrix and optimise hydration, which can improve filler integration and longevity. Post-treatment, it soothes the skin and supports recovery. Many aesthetic practitioners recommend it as part of a filler maintenance protocol.
Skin feels smoother and more hydrated from first application. Visible improvements in skin tone, brightness, and texture are typically noticeable from 14 days of consistent use.
Yes. The formula is suitable for all skin types, including sensitive and reactive skin. It is free from ingredients commonly associated with irritation and has been dermatologically tested for safety and tolerability.
Yes. TEOXANE RHA Serum layers well with vitamin C serums, retinoids, and peptide-based products. Apply it after lighter serums and before moisturiser. If using alongside prescription actives such as tretinoin, apply the RHA Serum first to help buffer the skin and reduce potential irritation.
The RHA® technology is inspired by and developed from TEOXANE's filler research — the same commitment to preserving the natural structure of hyaluronic acid that underpins their injectable range. While the topical serum and injectable fillers are different products with different formulations, they share the same scientific philosophy around HA biocompatibility.
