iS Clinical lip care products deliver pharmaceutical-grade treatment to the delicate lip area — combining exfoliation, hydration, and sun protection in targeted formulations that support the appearance of smoother, fuller-looking lips. Each product in this collection addresses a specific aspect of lip health, from resurfacing to daily UV defense.

Lip Polish is a dual-action exfoliating treatment that uses sugar crystals and botanical lipids to buff away dry, flaky skin while delivering conditioning moisture. The result is the appearance of smoother, softer lips that are optimally prepared for subsequent treatments. For intensive lip restoration, Youth Lip Elixir combines peptides and Hyaluronic Acid to support the appearance of plumper, more defined-looking lips with visibly refined lip lines.

Lip Duo pairs exfoliation and hydration in a convenient two-step set, providing a complete lip care protocol. For essential daily protection, LIProtect SPF 35 shields the lips from UV exposure with broad-spectrum mineral sun protection in a hydrating, non-sticky formula.

Lip skin is thinner and more vulnerable to environmental stressors than facial skin, making dedicated care essential. Apply lip treatment after your facial serums and include lip-specific sun protection daily. Trusted by professionals in 120+ countries.
