ISDIN Si-Nails Strengthener

ISDIN Si-Nails is a professional-grade nail strengthener designed to improve the quality and appearance of fragile nails. The product is developed and manufactured by ISDIN, a leading Spanish dermatology brand founded in 1975.

The brand's origin lies in a joint venture between two prominent Spanish companies: the Puig Group, a global luxury fashion and fragrance powerhouse, and Esteve, a major international pharmaceutical group. This partnership combines dermatological pharmaceutical expertise with cosmetic elegance. The manufacturing primarily takes place in Spain, ensuring high quality control standards in accordance with European cosmetic regulations. Today, ISDIN remains under the shared ownership of the Puig and Esteve families, maintaining its status as a premier global dermo-cosmetic brand headquartered in Barcelona.
