Description
ISDIN Si-Nails is a nail strengthening serum for weak, brittle nails that break or split easily. Organic silicon (silanediol salicylate) and cationic hyaluronic acid help strengthen and hydrate the nail, while Pistacia lentiscus gum and biosaccharide gum-2 form a protective film.
The invisible, fast-absorbing formula also moisturises the cuticles to keep them supple. The click-pen brush makes it quick to apply every day, and ISDIN reports visible results in 14 days.
