PCA SKIN ExLinea Peptide Smoothing Face Serum 1.0 oz Pump — Targets Fine Lines with Hyaluronic Acid & Squalane

PCA SKIN ExLinea Peptide Smoothing Face Serum is a concentrated peptide spot treatment designed to hydrate, visibly smooth expression lines, and support firmer-looking aging skin.

This lightweight, parfum-free serum blends peptides with squalene and sodium hyaluronate to target fine lines around the eyes, forehead and mouth while delivering lasting moisture. Formulated without parabens, synthetic dyes or fragrances, it layers easily with your existing skincare routine and is intended for twice-daily application after cleansing and toning. The formula combines humectants and emollients to plump the skin surface and support a more resilient texture over time.

How does this serum reduce the look of fine lines and expression wrinkles?

The ExLinea formula uses peptides to help modulate signals that contribute to visible expression lines while sodium hyaluronate attracts and holds moisture at the skin surface. Regular application helps the skin look smoother and appear more even in texture. It’s a targeted spot treatment, so a little product goes a long way on problem areas.

• Peptides help support a smoother-looking surface where repeated movement creates lines.
• Sodium hyaluronate draws moisture into the outer layers for immediate plumping.
• Squalene and rice bran wax lock in hydration and improve skin feel.
• Use sparingly on areas of expression for focused results.

Will this serum work with my current skincare routine?

Yes — the serum is designed to layer under creams and sunscreens or over light hydrators. Because it’s free from fragrances and dyes, it’s generally compatible with other active ingredients, though patch testing is recommended when combining strong actives. Apply it after cleansing and toning, before heavier moisturizers.

• Apply twice daily to clean skin for best absorption.
• Follow with moisturizer or facial oil to seal in benefits.
• Safe to use under daytime sunscreen or nighttime treatments.
• Patch test when pairing with exfoliating acids or prescription actives.

What key ingredients are in the formula and what do they do?

The serum pairs proven hydrating agents with emollients and peptides to address texture and moisture. Sodium hyaluronate provides multi-depth hydration while squalene restores a supple feel. Rice bran wax helps create a smooth application and supports a softer skin surface after use.

• Sodium hyaluronate — attracts and retains moisture for visible plumping.
• Squalene — lightweight emollient that softens and nourishes skin.
• Peptides — peptide complexes that target expression-prone areas.
• Rice bran wax — improves texture and helps the serum glide on evenly.

How quickly will I notice results and how should I apply it?

Some immediate hydration and smoothing can be seen after the first application due to hyaluronic acid’s moisture-binding effect, while visible changes in wrinkle depth and texture often develop with consistent use over weeks. Apply a small pump to targeted lines twice daily and gently pat until absorbed.

• Use a pea-sized amount on each treatment area; avoid excess product.
• Pat gently around eyes, mouth, and forehead — do not rub vigorously.
• Daily morning and evening use provides cumulative benefits.
• Complement with sunscreen each morning to protect results.
