A highly concentrated night serum designed to target early signs of ageing, support skin regeneration, and restore elasticity. Powered by a dual-peptide complex and minimalist formula, it works overnight to revitalise tired skin and improve the appearance of fine lines.

The gentle, 10-ingredient formula features EGF (sh-Oligopeptide-1) and bFGF (sh-Polypeptide-1)—two skin-compatible peptides that help accelerate cell turnover, promote collagen synthesis, and visibly smooth wrinkles. Guaiazulene, a calming blue compound derived from chamomile oil, helps reduce redness and irritation while lending the serum its signature tint. Suitable for all skin types, including sensitive, this fast-absorbing serum leaves no sticky or greasy residue.

Clinically tested for primary skin irritation and sensitive skin compatibility, this vegan and cruelty-free formula is ideal for nightly use to support a firmer, more youthful-looking complexion.
