Eighth Day

Details

The flagship formula from Eighth Day — a patented, clinically proven serum powered by the highest concentration of the brand's proprietary Peptide-rich Plasma®, a complex of 24 bioidentical peptides, amino acids, and growth factors that communicate directly with skin cells in their own biological language to stimulate renewal, restoration, and regeneration. Developed by board-certified dermatological surgeon Dr. Antony Nakhla — whose work with over 10,000 surgical patients revealed the skin's extraordinary innate capacity to heal — the Regenerative Serum targets 10 visible signs of aging simultaneously, including fine lines, wrinkles, firmness, elasticity, volume, pore size, dehydration, sun damage, texture, and tone. After 4 weeks: 100% of users agreed it smoothed fine lines and wrinkles, 100% agreed their skin was firmer and tighter, and 97% saw significant measurable improvement in skin firmness and elasticity using a Cutometer®. Clinically measured 44.4% improvement in skin firmness. Bioidentical technology. Clean science. Safe for sensitive skin. Unisex and suitable for all skin tones.

How To Use

Apply morning and evening to clean skin. Dispense 4–5 drops onto fingertips and gently sweep over the face and neck in an upward motion. Follow with moisturiser. For optimal results, use consistently as the serum step within a complete Eighth Day routine.
