The UREADIN ULTRA40 gel-oil by ISDIN offers intense exfoliation for particularly thickened regions, including specific calluses and deformed nails. It serves as a supportive agent in treating fungal infections as well as conditions like flat warts, onychogryphosis, and nail psoriasis. Key advantages include the reduction of localized skin and nail thickening due to ISDIN Urea's effectiveness. Additionally, it enhances the absorption of antifungal medications by softening the upper layers of skin and nails. With its gel-oil consistency, it ensures optimal cosmetic appeal, promotes deeper penetration, and maintains the stability of ISDIN Urea at a concentration of 40%.
