Most listings recommend normal and sensitive skin; at least one listing also specifies suitability for mature and dry skin.
Reviewers commonly report day‑long or overnight protection, typically around 12–24 hours, with some accounts of 24+ hours; a minority say they reapply after intense activity.
Listings highlight niacinamide and xylitol esters as supporting ingredients, with mandelic acid noted as a primary active among the AHA components.
Users describe a serum texture that requires some drying/absorption time and can feel slightly sticky for some, but many report it dries clear and leaves no visible residue or staining.
