Eustofeyce Deep Collagen Silk Peptide Serum 35 ml — Anti‑Aging, 72‑Hour Hydration & Elasticity

Eustofeyce Deep Collagen Serum Silk Peptide Ampoule is a 35 ml anti-aging facial serum that combines silk peptides and palmitoyl pentapeptide-4 to smooth fine lines, boost elasticity and deliver up to 72 hours of deep hydration.

This lightweight ampoule is built to target texture, firmness and surface dehydration without heavy residue. The formula uses soluble silk peptide fibers and a hydrolyzed protein blend designed for quick absorption, and it’s labeled cruelty-free for everyday use. Apply three drops morning and night after cleansing to help skin look smoother and feel more elastic.

How quickly will I see smoother skin?

Visible smoothing of fine lines can be noticed soon after application because the silk peptide fibers help fill texture gaps on the skin’s surface. Continued use supports longer-term improvement in skin feel and resiliency when combined with sun protection and routine care.

• Immediate surface smoothing from soluble silk peptide fibers
• Regular use supports improved elasticity and reduced appearance of lines
• Designed for fast absorption to layer under moisturizers or makeup

What kind of hydration does this serum provide and how long does it last?

The ampoule is formulated to deliver sustained moisture through a combination of hydrating peptides and soluble silk strands that help retain water in the upper skin layers. The brand describes continuous hydration effects lasting up to 72 hours, especially when the serum is applied to clean skin and sealed with a moisturizer.

• 72-hour hydration support claimed by the formula’s composition
• Lightweight texture good for layering with creams or sunscreens
• Recommended application: three drops, morning and night, after cleansing

Is this serum suitable for sensitive or daily-use routines?

The product uses a mild hydrolyzed protein blend intended for comfortable wear and rapid absorption, which aims to minimize irritation for many users. Because reactions vary, patch testing is recommended before daily use, and it’s easy to incorporate as a step under daily moisturizer or as part of a targeted night-time regimen.

• Cruelty-free and described as gentle on skin
• Hydrolyzed proteins for softer, fast-absorbing texture
• Suitable for layering; perform patch test if you have highly reactive skin

How should I use the ampoule for best results?

Apply to clean skin, focusing on areas with fine lines or reduced elasticity, and allow the serum to fully absorb before adding heavier creams or makeup. Consistency is key: three drops morning and night is the recommended routine to support texture refinement and hydration retention.

• Step 1: Remove the clear cap and dispense three drops
• Step 2: Pat onto forehead, laugh lines and targeted areas after cleansing
• Step 3: Allow absorption then follow with moisturizer or sunscreen
