COSRX unveils a blue peptides and bakuchiol anti-ageing serum

The Korean skincare brand COSRX is unveiling the Blue Peptide Bakuchiol Plump Glow Serum, a new serum designed to visibly improve skin firmness, elasticity, and plumpness. Available on Amazon and the brand’s website, the product aligns with the growing trend of treatments targeting preventive skin aging and facial volume loss.

At the core of the formula is Blue Peptide (Copper TriPeptide-1), a naturally blue copper peptide known for supporting skin structure and resilience. The serum also combines bakuchiol – a plant-based alternative to retinol considered less irritating – with a complex of five peptides aimed at improving texture, radiance, and skin tone.

COSRX also highlights the rise of GLP-1 treatments and significant weight loss, which can contribute to facial volume loss. The brand positions the serum as a response to concerns related to firmness and facial contour support, while continuing its strategy of offering accessible peptide-based skincare following the success of its peptide- and collagen-enriched products.
