Smooth Away Fine Lines with the Power of Peptides

Fine lines and wrinkles don't have to be permanent fixtures on your face. The PCA Skin ExLinea Pro Peptide Smoothing Serum is a physician-developed, clinically advanced formula designed to visibly reduce the appearance of expression lines and deep-set wrinkles with consistent daily use. Powered by a targeted blend of peptides that work to relax facial muscle contractions — the very mechanism behind expression lines — this serum delivers a smoother, more youthful-looking complexion without needles, without downtime, and without compromise.

Peptide Science That Speaks for Itself

ExLinea Pro features a sophisticated peptide complex that mimics the effect of muscle-relaxing treatments by signaling skin cells to reduce the repetitive contractions that deepen lines over time. Combined with additional skin-conditioning actives, the formula also improves overall skin texture, hydration, and radiance. The result is skin that looks noticeably smoother, plumper, and more refined — the kind of improvement that makes people ask what you've been doing differently. Suitable for all skin types, including sensitive skin, and pairs seamlessly with your existing PCA Skin regimen or any clinical skincare routine.

Pro-Grade Results in a Precision-Sized Bottle

The 1 oz / 30 ml bottle is perfectly calibrated for a targeted daily treatment — a little goes a long way with this concentrated peptide formula. Apply a few drops to cleansed skin morning and evening, focusing on areas of concern like the forehead, crow's feet, and smile lines. With fast US shipping, your peptide-powered smoothing routine is just days away from starting.
