Peptide Facial Refining Concentrate

Five peptides, five jobs

Acetyl hexapeptide-8 and acetyl octapeptide-3 both target the look of expression lines by softening the muscle-driven creasing at the forehead and eye corners, the same territory injectables address chemically. Two palmitoyl dipeptide-5 complexes work on visible firmness, and a synthetic peptide modelled on tree-viper venom, better known by its ingredient-house name Syn-Ake, rounds out the line-relaxing bench.

The ZO complex, again

Laminaria digitata and Opuntia stem extracts, the same antioxidant bench running through Daily Power Defense and Firming Serum, sit underneath the peptide work, with hyaluronic acid, squalene and phospholipids carrying it all into skin.

Why five peptides in one bottle

Expression lines and structural firmness are two different problems with two different mechanisms; most serums pick one. This concentrate is built to run both fronts at once, which is the case for its price and its place at the top of the ZO range.

Established skincare users focused on expression lines and the first real loss of facial firmness; anyone who has exhausted single-peptide serums and wants the fuller mechanism; and skin already on a ZO routine ready for its most concentrated step.

Worth knowing

Fragrance-free. A premium, concentrated formula best layered thin: a little covers the whole face. Results with peptide serums build over weeks of consistent use, not days.

Morning and evening on cleansed skin: a small amount, about the size of a pea, pressed over face and neck before moisturiser.

Concentrate it where expression lines are most pronounced, forehead, frown and eye corners, in addition to full-face application.

Use alongside

Daily Power Defense in the morning for antioxidant cover, a retinoid at night on alternate evenings, and always SPF to protect the investment. It layers under any ZO moisturiser without disturbing either.
