Damaged, dull or uneven skin is usually a sign that your barrier needs support — and early fine lines are a sign it needs something more targeted. The Studd Muffyn GHK-Cu Copper Peptide + Acetyl Hexapeptide-8 Serum Duo gives you both in one focused routine.

GHK-Cu Copper Peptide Serum is powered by GHK-Cu, a well-known copper peptide that supports collagen production and skin regeneration. It works to improve texture, reduce the appearance of marks and help skin look more even over time, while strengthening your skin barrier so it stays protected and balanced. The formula is lightweight and absorbs quickly, so it never feels heavy or sticky.

Acetyl Hexapeptide-8 Serum is powered by Acetyl Hexapeptide-8 (commonly known as Argireline) and is designed to help smooth the appearance of fine lines and improve overall texture without weighing skin down. It targets both dynamic lines caused by facial expressions and static lines visible even at rest, helping skin look smoother, more relaxed and refined.

Why you will like it:

• Supports skin repair, recovery and collagen for healthier-looking skin
• Helps improve marks and uneven texture
• Helps reduce the appearance of fine lines, crow's feet and frown lines
• Works on both dynamic and static lines
• Strengthens the skin barrier over time
• Lightweight, non-greasy and suitable for all skin types

With consistent use, skin starts to feel stronger, smoother and more refined. Both serums layer well with each other and the rest of your routine, so you can use them comfortably in your morning and night rituals without any sticky or greasy residue.
