Expensive peptide hype in an alcohol-heavy formula—not a retinoid-level wrinkle treatment.

READ MORE

The efficacy score is 3.4/5: niacinamide is positioned very high, while gluconolactone and salicylic acid may provide modest texture and pore benefits, but their concentrations and pH are undisclosed. The two expression-line peptides are placed near the end, so they may contribute but cannot justify dramatic anti-wrinkle claims. The formula also contains denatured alcohol at position 6, which can reduce tolerability, particularly for dry or sensitive skin. The real strengths are humectant hydration, niacinamide, and mild exfoliation—not the marketed peptide positioning.
