AquaFirm: How GHK-Cu and SNAP-8 Work Together for Firmer, Smoother Skin

AquaFirm was created with two peptides supported by strong research: Copper Tripeptide-1 (GHK-Cu) and Acetyl Octapeptide-3 (SNAP-8). Each focuses on a different part of visible aging. When paired together, they offer a targeted approach to firmness, renewal, and smoothing expression lines.

What Is GHK-Cu? (Copper Tripeptide-1)

GHK-Cu is a naturally occurring copper peptide studied for its role in collagen, elastin, and skin repair. It supports a firmer, more balanced appearance over time.

Research Highlights:

• Review showing increased collagen, elastin, and improved dermal repair

• Human study showing improved firmness, density, and visible reduction in fine lines

In AquaFirm, GHK-Cu acts as the structural-support peptide, helping skin look more lifted with consistent use.

What Is SNAP-8? (Acetyl Octapeptide-3)

SNAP-8 is a small peptide designed to reduce the appearance of expression lines by easing the visible impact of repeated facial movement. It works especially well for areas like the forehead, crow’s feet, and elevens.

Research Highlights:

• Review covering neuromodulatory peptides, including SNAP-8

• Clinical data showing a 34–38% reduction in wrinkle depth

In AquaFirm, SNAP-8 delivers the visible smoothing effect that pairs well with GHK-Cu’s deeper-acting benefits.

Why These Peptides Work Better Together

AquaFirm combines two complementary actions:

• GHK-Cu supports collagen, elastin, and renewal
• SNAP-8 softens the look of dynamic expression lines

This creates a dual-effect outcome: firmer-looking skin and smoother-looking lines. This focused pairing is what sets AquaFirm apart from single-peptide formulas.
