ENDOCARE RENEWAL Retinoid Serum is a dual-retinoid serum designed to visibly smooth fine lines, refine skin texture and support firmer-looking skin. Powered by exclusive RetinDuo® Technology, it combines pure retinol in microsponges with AOX Tech-encapsulated retinal, supported by a targeted, natural booster complex to optimise bioavailability and enhance retinoid stability.

Its intelligent dual-delivery system helps optimise retinoid performance while minimising irritation. In clinical evaluation, 90% of users reported softer skin and reduced fine lines, with 85% noting improved texture after 28 days.* Enriched with cross-linked hyaluronic acid and niacinamide to support hydration and reinforce the skin barrier, this fragrance-free retinoid serum is suitable for all skin types and positioned as the first step in the ENDOCARE RENEWAL Retinoid progression.
