PCA Skin’s Exlinea Pro Peptide Serum targets visible expression lines with a Peptide-Pro Complex and neuropeptides that help relax dynamic wrinkles and support a firmer, lifted look in areas prone to sagging. With consistent use, skin appears more sculpted and smoother across the eyes, forehead, and mouth, while the formula helps strengthen the skin barrier by thickening the epidermis and improving moisture retention for a plumper feel and less noticeable lines.This gentle, results-driven blend also helps brighten and even overall tone, addressing the look of dark spots and hyperpigmentation as part of a preventative regimen, and layers well with exfoliants and other targeted PCA Skin actives to enhance smoothing and firming benefits over time.
