One Skincare System.<\/strong><\/p>\n<p>Brightening Vitamin C Serum Next-Gen forms the foundation of the morning ritual: it helps protect skin from daily oxidative stress, reduce dullness and restore radiance. X-Strength Retinol Serum Next-Gen works in the evening, supporting skin renewal and reducing the appearance of wrinkles, uneven texture and post-acne marks.<\/p>\n<p><strong>Why Choose This Set?<\/strong><\/p>\n<p>The morning formula combines <strong>15% THD Vitamin C, 3% Niacinamide and Tripeptide-5<\/strong> to address uneven tone and visible signs of ageing. The evening serum contains a <strong>5% Granactive Retinoid complex and 3% Blue-Green Algae Extract<\/strong>, complemented by P3 Peptide. The stated 5% refers to the Granactive Retinoid complex, rather than the concentration of pure retinol.<\/p>\n<p>In both formulas, <strong>squalane and a hyaluronic acid complex<\/strong> help maintain hydration.
