SkinCeuticals P-TIOX Peptide Serum and HA Intensifier Multi-Glycan Serum form a curated anti-ageing duo designed to target expression lines, fine lines, dehydration, loss of facial volume, and dullness. P-TIOX combines an Advanced Peptide Complex with 5% PHA, 5% Niacinamide, and 1% Laminaria Extract to visibly smooth expression lines, refine skin texture, and enhance glass-skin radiance. HA Intensifier Multi-Glycan combines 1.3% Hyaluronic Acid, 12% Proxylane, post-biotic ferment, Licorice Root Extract, and Purple Rice Extract to provide long-lasting hydration, support skin hyaluronic acid levels, and visibly plump facial contours. Used together, the duo supports smoother, firmer, more volumized, and radiant-looking skin.
