## Summary

A definitive retinol serum in a sleek black bottle featuring a decorative tortoiseshell-patterned cap, designed for skin renewal and resurfacing.

## Description

Formulated to renew skin overnight, this next-generation serum resurfaces texture, improves tone, and helps reduce the appearance of fine lines and discoloration. A powerful pairing of encapsulated retinol and bakuchiol drives cellular turnover, supporting the skin’s natural regeneration process with less irritation than traditional retinoids. Lactic and glycolic acids provide gentle exfoliation to smooth and brighten, while antioxidant-rich botanicals help neutralize free radical damage. A complex of ceramides and hyaluronic acid works to replenish moisture and reinforce the skin’s protective barrier, maintaining hydration throughout the night. With continued use, skin appears clearer, firmer, and more luminous—restored to a healthier, more even complexion by morning. INSIDE THE FORMULA   Encapsulated Retinol: Stabilized vitamin A promotes collagen synthesis and accelerates cell turnover for smoother, more radiant skin.   Bakuchiol: A gentle, plant-based retinol alternative that targets lines and pigmentation while calming inflammation.   Ceramide Complex: Strengthens the skin barrier and locks in moisture to reduce sensitivity and dryness.   CLINICAL RESULTS  96% reported brighter, more radiant skin after 28 days 92% of participants saw improved hyperpigmentation (13.5% average improvement) 15% average reduction in wrinkle depth after 28 days
