WHAT IT DOES - pH-optimized retinol at 2000 IUs — buffered to maintain stability at the precise pH where retinoid receptors in dermal fibroblasts are most responsive, minimizing irritation while maximizing collagen gene expression - Activates retinoid receptors (RAR/RXR) — signals fibroblasts to increase procollagen synthesis, the precursor to the collagen triple-helix that determines skin firmness and wrinkle depth - Niacinamide (B3) barrier support — strengthens ceramide production in the stratum corneum, reducing transepidermal water loss that commonly accompanies retinol use - Squalane + avocado oil delivery — lipid-compatible vehicles that transport retinol through the stratum corneum while reinforcing the skin barrier - Calibrated for Level 2 tolerance — formulated for skin that has adapted to Level 1, targeting mild to moderate wrinkles, uneven texture, and fine pores
WHO ITS FOR Mild to Moderate Wrinkles, Uneven Texture, Fine Pores
KEY INGREDIENTS Retinol, Niacinamide, Avocado, Coconut Oil, low molecular weight hyaluronate, squalene

50ml - A specialized blend of buffered retinol formulated to be gentle on the skin yet effective enough for visible change. At this level, 2000 IUs of retinol encourage collagen and elastin production to soften mild to moderate lines you may be noticing on your forehead, between your brows and around your eyes. Blended with the retinol are niacinamide (B3), avocado and coconut oil to help enhance its effectiveness deep within the skin matrix. On the surface, a moderate exfoliation occurs, which helps to improve firmness, texture and undertone.
