Functions Overview (15)

Texture & Feel

Texture & Feel

Expected texture
Viscous, serum-like — slightly "thick water" feel
SpreadabilityVery easy
AbsorptionVery fast
Tackiness / ResidueNone
Finish:Luminous / radiant — subtle light-reflecting glow

Silicones create a smooth, velvety "slip" with a blurring sensory effect. Slight initial tackiness that fades into a hydrated dewy finish. Cooling sensation on application with rapid dry-down.
