ISDIN FotoUltra 100 Active Unify Fusion Fluid SPF 50+ is a high-protection facial sunscreen formulated to prevent and reduce hyperpigmentation, including melasma and sun-induced dark spots. Its DP3-Unify Complex—featuring Niacinamide, Phenylethyl Resorcinol, and Tetrapeptide-30—targets melanin production to unify skin tone. Broad-spectrum UVA/UVB filters like Octocrylene, Titanium Dioxide [Nano], Butyl Methoxydibenzoylmethane (Avobenzone), and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S) offer SPF 50+ protection. Enriched with Vitamin E (Tocopheryl Acetate), Panthenol, Allantoin, and Sodium Hyaluronate, it provides antioxidant defense and hydration. The lightweight Fusion Fluid texture absorbs quickly without leaving a greasy residue, making it suitable for daily use under makeup. Dermatologically tested and water-resistant.
