Eustofeyce Deep Collagen Silk Peptide Serum 35ml — Lightweight Korean Anti-Aging, 72H Hydration & Elasticity

Eustofeyce Deep Collagen Serum Silk Peptide Ampoule is a lightweight Korean anti-aging serum that hydrates up to 72 hours while smoothing fine lines and improving skin elasticity.

This silk peptide ampoule combines hydrolyzed silk peptide fibers and palmitoyl pentapeptide-4 in a fast-absorbing, cruelty-free formula designed to deliver lasting moisture and a firmer-looking complexion. The 35 ml dropper bottle provides a targeted, easy-to-use dose—recommended three drops morning and night—so you can layer it into an existing skincare routine without adding weight or greasiness.

How does this serum reduce the appearance of fine lines?

The serum uses soluble silk peptide fibers that slip into surface texture gaps to visually smooth fine lines and support a more even skin surface. Palmitoyl pentapeptide-4 helps provide a plumping impression by supporting the skin’s natural structure, producing a softer look where lines appear.

• Silk peptide fibers fill and smooth shallow texture gaps.
• Palmitoyl pentapeptide-4 promotes firmer-feeling skin appearance.
• Lightweight, fast-absorbing base avoids heavy film over lines.

How long does the hydration last and how should I apply it?

This formula is designed for extended moisture retention, with clinical-style messaging that it can maintain hydration benefits for up to 72 hours when layered into a complete routine. For best results, apply three drops to clean skin morning and night, focusing on forehead, laugh lines and other areas that need smoothing.

• Apply after cleansing and toning, before heavier creams.
• Use 3 drops morning and evening for targeted coverage.
• Allow full absorption before adding sunscreen or makeup.

Is the formula suitable for sensitive or daily use?

Eustofeyce Deep Collagen Serum is formulated with a mild hydrolyzed protein blend that absorbs quickly and is intended for everyday use on most skin types. The cruelty-free formula avoids animal testing and aims for gentle performance, but patch testing is recommended for highly reactive skin.

• Gentle hydrolyzed proteins for comfortable absorption.
• Cruelty-free formulation, not tested on animals.
• Compatible with layering under moisturizer and sunscreen.

Can it help improve skin texture and firmness?

The combination of silk peptides and targeted peptides is crafted to refine surface texture and encourage a firmer aesthetic over consistent use. Visible results depend on regular application and integration with complementary skincare steps like sun protection and hydration.

• Refines texture for a smoother, glass-skin look.
• Boosts elasticity-supporting peptide activity.
• Works best when used consistently within a daily routine.

Who is this for: Eustofeyce Deep Collagen Serum Silk Peptide Ampoule is designed for anyone seeking a lightweight, non-greasy anti-aging step that targets fine lines, hydration and texture—ideal for people with normal to dry or combination skin who want a cruelty-free Korean skincare solution that fits into morning and evening routines.
