ISDIN Si-Nails is a specific strengthener designed to protect nails and cuticles while visibly improving their appearance, with results noticeable in just 14 days. Cationic Hyaluronic Acid penetrates deeply to deliver the hydration nails and cuticles need to stay flexible and healthy-looking. Mastic oil, sourced from Pistacia Lentiscus resin, helps stimulate the synthesis of hard keratins and supports their binding to proteins, contributing to nail hardness and improved architecture. Organic Silicon, in the form of Silanediol Salicylate, increases the nail's silicon content and remineralizes the nail matrix to help promote nail growth in good condition, while Biosaccharide Gum-2 creates a lightweight, invisible film that helps protect against daily external aggressions. The click-pen applicator makes daily use effortless, gliding on clean and clear over bare nails or polish alike, with a finish that disappears the moment it's applied. To use, apply nightly to clean, dry nails. Avoid contact with water for up to 6 hours after application, or reapply after washing your hands. Prime the pen with roughly 25 clicks on first use until the brush is wet. After that, just one click per nail is all you need. Review: BUY IT - It’s cheaper here than the pharmacy.
