Introducing Cetpro® APPS: A Next-Generation Vitamin C Derivative
June 29, 2026PDRN PHYCOPEPTIDE is a second-generation PDRN active by CODIF enriched with 2,434 bioactive phycopeptides, designed for advanced anti-ageing and firming formulations. Traditionally, PDRN is sourced from salmon or rainbow trout, whereas PDRN PHYCOPEPTIDE is derived from Chlorella vulgaris, cultivated in France, making it a vegan alternative.
It combines regenerative PDRN technology with collagen-supporting phycopeptides to deliver visible skin density and tightening benefits. PDRN PHYCOPEPTIDE is COSMOS approved with its key performance claims including activation of growth factors, stimulation of collagen expression across all skin layers, and clinically observed firming effects after 28 days. This active was developed specifically with mature skin, neck, and décolleté applications in mind.

Why are formulators paying attention?
-
Vegan regenerative technology: low molecular weight PDRN (<50kDa) combined with 2,434 phycopeptides to support skin regeneration and collagen pathways.
-
Collagen 360° activation: helps reactivate collagen expression in the dermis, dermal–epidermal junction, and epidermis.
-
Supports skin density and firmness: in vitro data showed stimulation of multiple fibroblast growth factors (FGF2, FGF5, FGF7, FGF13) and increased collagen-related markers.
-
Tensor effect validated in vivo: after 28 days of use at 2%, skin deformation decreased by an average of 8.4%, with reductions of up to 46% in some volunteers.
-
Sustainable biotechnology sourcing: Chlorella cultivated in France using renewable energy and a high recycled-water process.
