Why choose Dual ?
Dual is not just a serum — it's a structural skincare solution.
Dual is formulated with clinical precision — only two ingredients: purified water and high-purity, bioidentical Type III and XVII collagen.
- Type III Collagen: targets the dermis, enhancing firmness and restoring elasticity.
- Type XVII Collagen: works at the dermal-epidermal junction, strengthening structural cohesion to counteract sagging.
No fragrance. No filler. No unnecessary complexity.
