Yeweian GHK‑Cu SNAP‑8 Peptide Serum 1 fl oz — Copper Peptide + Hyaluronic Acid for Firming & Fine Lines

Yeweian GHK-Cu SNAP-8 Peptide Serum is a lightweight anti-aging face serum that blends copper peptide and SNAP-8 with hyaluronic acid to hydrate, smooth the look of fine lines, and help support firmer-looking skin.

This concentrated 30 ml (1 fl oz) formula pairs GHK-Cu (a copper-containing tripeptide) with SNAP-8 (an expression-smoothing peptide) plus hyaluronic acid and nourishing botanicals. The result is a multi-targeting serum designed for daily use under moisturizers and sunscreen to improve hydration, texture, and the visible signs of aging without a heavy finish. The dropper bottle allows precise dosing so you can add one to two drops to your routine where you need them most.

How does this serum help reduce the appearance of fine lines and wrinkles?

The dual-peptide combination works in two complementary ways: SNAP-8 aims to ease repetitive muscle movements that contribute to expression lines while GHK-Cu is included for its supportive role in skin repair and firmness. Together they help the skin look smoother and more resilient when used consistently as part of a skincare routine.

• SNAP-8 (acetyl hexapeptide-8) to help soften expression-related lines.
• GHK-Cu (copper tripeptide-1) to support skin structure and surface texture.
• Palmitoyl pentapeptide-4 and tri/other peptides for layered peptide support.
• Use morning and/or night for cumulative visible improvements.

Will this serum keep my skin hydrated without feeling greasy?

Yes — the formula includes sodium hyaluronate and humectants like glycerin to attract and retain moisture while maintaining a lightweight, fast-absorbing texture. It layers well beneath creams and makeup, giving a plumped, dewy look without heavy residue.

• Sodium hyaluronate provides multi-depth hydration and a plumping effect.
• Glycerin and propylene glycol help lock in moisture for longer wear.
• Lightweight base lets the serum absorb quickly under other products.

How should I apply the serum for best results?

Apply a few drops to clean, dry skin before heavier creams or oils. Gently pat the serum over areas with fine lines or where you want extra firmness; allow it to fully absorb then follow with your moisturizer and sunscreen in the daytime.

• Use 2–3 drops for face and neck, more for targeted areas.
• Apply morning and/or evening after cleansing and toning.
• Follow with moisturizer and daily SPF when used in the morning.

What are the key ingredients and are they safe for sensitive skin?

The serum combines peptides, humectants, niacinamide and botanical extracts to support skin appearance. While many users with normal-to-dry skin tolerate the formula well, those with very reactive skin should patch-test first because the blend includes active peptides and fragrance.

• Active: copper tripeptide-1, acetyl hexapeptide-8, sodium hyaluronate.
• Supportive: niacinamide for tone, plant extracts for antioxidant support.
• Contains fragrance (parfum); patch test if you have fragrance sensitivity.

Who is this for: Yeweian GHK-Cu SNAP-8 Peptide Serum is made for anyone seeking a targeted anti-aging step that adds hydration plus peptide support to help smooth expression lines and improve skin texture. It’s suitable for daily use by adults looking to boost moisture and the visible firmness of aging or prematurely aged skin—ideal as part of a layered routine under moisturizer and SPF. If you have very sensitive or reactive skin, try a small patch first and introduce gradually.
