Teosyal Puresense Redensity 2 marries 15 mg/ml hyaluronic acid—80 % lightly cross-linked, 20 % free—with a nutrient Resilient Complex of eight amino acids, three antioxidants (glutathione, N-acetyl-cysteine, alpha-lipoic acid), two minerals (zinc, copper) and vitamin B6. The dual HA fraction balances lift and fluidity: cross-linked chains give structure, while free HA ensures seamless integration and hydration. Built-in 0.3 % lidocaine trims peri-orbital discomfort by about 45 % compared with anaesthetic-free injections, all while preserving a physiologic pH near 7.
BDDE residues stay well below the EU’s 2 ppm ceiling; endotoxin tests read under 0.5 EU/ml. Rheology places the elastic modulus around 55 Pa—soft enough to flex with blinking, cohesive enough to resist migration. Particle size averages 150–180 µm, gliding through a 30 G needle yet anchoring securely within the arcus marginalis. Hydration trials show less than 8 % water uptake, key to preventing day-two eyelid puffiness. Fibroblast studies show a 30 % rise in type I collagen transcription after seven days, proving the amino-acid payload drives real dermal remodelling.
