Teosyal RHA4 is an innovative dermal filler that adapts to your facial dynamics, helping you achieve smoother, more youthful-looking skin without sacrificing natural expression. Using cross-linked hyaluronic acid designed specifically to support dynamic areas of the face, this premium formulation targets deep wrinkles and volume loss in mature skin. Its resilience ensures lasting correction while maintaining natural movement and flexibility during facial expressions.
Science Behind Teosyal RHA 4
Teosyal RHA 4 is part of the Teosyal fillers range developed by the Swiss company Teoxane Laboratories. It belongs to the innovative RHA (Resilient Hyaluronic Acid) line, a collection of Teosyal products formulated to support the skin during everyday facial movements. Unlike other dermal fillers, Teosyal RHA4 contains a unique network of resilient acid that preserves the natural structure of HA molecules.
The hyaluronic acid content in this cosmetic filler allows it to integrate seamlessly into the deep skin layers, helping to recreate volume where ageing has reduced firmness. This formulation of cross-linked hyaluronic ensures consistent elasticity and durability, even in areas subject to constant motion.
Teosyal RHA4 Key Properties
- RHA technology: uses both natural hyaluronic acid and advanced cross-linking for longevity.
- Elastic structure: maintains flexibility to accommodate facial movements and natural movement.
- Hydration boost: attracts and retains moisture to support the skin and visibly smooth lines.

Composition and Safety
Teosyal RHA 4 combines 23mg ml HA 3mg ml lidocaine hydrochloride to ensure a comfortable injection process. This means that discomfort is greatly minimized, allowing practitioners to slowly inject the gel precisely into the desired treatment area.
Each box contains 2 x 1.2 ml pre filled syringes, designed for optimal control and safety. The inclusion of traceability labels ensures full product authenticity and transparency.
The Teosyal RHA4 formulation features:
- Cross linked hyaluronic acid designed specifically for dynamic facial zones.
- A phosphate buffer to maintain pH stability.

Its unique balance of natural hyaluronic acid and resilient cross-linked chains allows practitioners to avoid injecting into superficial layers, targeting deeper structures for more optimal results.
Hyaluronic Acid: Mechanism of Action
As a next-generation dermal filler, Teosyal RHA 4 works by replacing lost hydration and volume in the deep skin layers. The gel structure gently expands beneath the surface to restore volume and smooth the wrinkles, while maintaining flexibility so that facial mobility remains natural.
The filler’s ability to support the skin during facial expressions ensures that treated areas remain supple and dynamic. As it binds water molecules, it helps recreates volume and structure, counteracting ageing and erases wrinkles without creating stiffness or distortion.
Clinical Performance and Results
Teosyal RHA 4 is ideal for patients who want long-lasting yet natural looking enhancement. The formulation integrates into the tissue to move harmoniously with the face, ensuring smooth transitions and balance across treated zones.
Expected Outcomes for Facial Movements
- Noticeably firmer and lifted appearance.
- Reduction of skin depressions and volume loss.
- Better hydration and elasticity.
- Youthful contours with restored harmony.
- Enhanced tone in thick skin areas prone to laxity.
The technology ensures that even under continuous facial movements, the wrinkle filler product maintains its shape and strength, giving a refreshed look that evolves naturally with your expressions.
Teosyal RHA4 Application Guidelines
Administered by trained aesthetic professionals, Teosyal RHA 4 should be injected carefully into the mid-to-deep dermis. Practitioners are advised to slowly inject small amounts while monitoring patient comfort and aesthetic outcome.
Important Recommendations:
- Always disinfect the treatment zone before the procedure.
- Avoid injecting into blood vessels or inflamed areas.
