Hero ingredients

• Retinol 1% (0.1% + 0.3% Retinyl Palmitate): Stimulates collagen production and cell turnover to diminish fine lines and improve skin texture over time.
• Bakuchiol 0.6%: A plant-derived retinol alternative that delivers similar anti-aging benefits while reducing redness and sensitivity during the retinization period.
• Ceramide Complex (NP, NS, AS, AP, EOP): Fortifies the skin barrier to prevent moisture loss and irritation caused by stronger actives.
• Peptide blend (Copper Tripeptide-1, Acetyl Hexapeptide-8, Palmitoyl Tripeptide-1): Supports skin firmness and elasticity while reducing the appearance of expression lines.

How to use

Apply 2-3 drops to clean, dry skin and gently pat in until absorbed. Start with once or twice weekly if you're new to retinol, then gradually increase frequency as your skin builds tolerance. Always follow with a broad-spectrum sunscreen during the day-retinol increases sun sensitivity.
