Cosmedix Elite Duo A Serum

Cosmedix Elite Duo A is a professional-strength, dual-phase vitamin A system designed to accelerate cellular renewal while maintaining optimal skin barrier integrity. This advanced treatment combines two synergistic formulations that work together to deliver high-performance retinol activity with supportive lipid replenishment, allowing the skin to receive the benefits of vitamin A while minimising irritation.

Formulated with a stabilised retinol complex, Duo A stimulates epidermal regeneration, improves dermal collagen production and helps normalise keratinisation. This process assists in refining skin texture, improving uneven tone, reducing congestion and visibly softening fine lines and wrinkles.

The two-step system allows vitamin A to penetrate effectively while the complementary phase replenishes essential lipids and antioxidants, supporting barrier repair and reducing the potential for inflammation or excessive dryness commonly associated with retinoid therapies.

Over time, consistent use supports clearer, smoother and more resilient skin, making Duo A an ideal corrective product within advanced skin treatment programs.
