Pro-Density Serum Peptides

peptide serum

From the age of 30, the skin produces less collagen each year. This isn't visible overnight – it's a slow erosion: skin texture thickens, contours slacken, skin loses its bounce. Hadonys Pro-Density peptide serum steps in precisely at this stage. Its complex of bioactive peptides stimulates fibroblasts, restores the dermal matrix, and gives the skin back its structural density – without harshness, without irritation.

✦ How peptides act on density

Peptides are protein fragments that act as cellular messengers: they signal to dermal fibroblasts to restart the synthesis of collagen, elastin, and hyaluronic acid. Unlike retinol, they do not aggressively accelerate cell renewal. Their action is deep, progressive, and perfectly tolerated, even on sensitive skin.

✦ Key active ingredients

GHK-Cu Copper Peptides — Activate fibroblasts, stimulate collagen I & III, strengthen the skin barrier, and neutralize free radicals.

Palmitoyl Tripeptide-1 (Matrixyl) — Targets the production of collagen and fibronectin in the dermis. Fills fine lines, improves tone, and smooths skin texture.

Multi-molecular weight hyaluronic acid — Three molecule sizes to act on the surface, deep down, and as a barrier. Instantly plumps and amplifies peptide penetration.

Niacinamide (Vitamin B3) — Tightens pores, evens skin tone, reduces micro-inflammations, and strengthens barrier function.

Panthenol (Pro-Vitamin B5) — Soothing, regenerating, gives the texture its fluidity without stickiness.
