Rejuner offers a range of products aimed at promoting collagen production through Claracel. These products primarily work by stimulating fibroblast growth and enhancing collagen synthesis, crucial for skin's elasticity and firmness. The brand comprises three variants: Rejuner Black Label, Rejuner Gold Label, and Rejuner Red Label, each tailored for specific facial areas or overall facial rejuvenation. Their application leads to notable improvements in skin texture, along with lifting, brightening, and moisturizing effects. Notably, Rejuner Gold Label is a premium injectable serum enriched with Polycaprolactone (PCL), designed to amplify collagen production, resulting in a more youthful appearance with enhanced skin texture, elasticity, and firmness. Following administration, the skin's collagen layer noticeably thickens over a span of four weeks.
