The science

Intelligent skincare starts with understanding the skin.

Rejna brings together modern biotechnology, established actives and purposeful botanicals to create intelligent formulas designed around the way skin looks, feels and changes over time.

Our approach is considered rather than complicated: support the skin barrier, target visible concerns, encourage renewal and protect against daily environmental stress.

    Peptide science

    Peptides are short chains of amino acids used in advanced skincare to target visible signs of ageing. Our eye cream features Matrixyl® 3000, a peptide complex combining Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7, alongside Red Algae, Vitamin A and replenishing hydrators.

    The result is precision care designed for the delicate eye contour.
