Brand note

Kerasal is a targeted treatment brand for nails and feet, built around keratolytic ingredients like urea and lactic acid. The Multi-Purpose Nail Repair is the clearest anchor: a dermatologist-backed formula that smooths, thickens, and clears discoloration on both fingernails and toenails. The Intensive Foot Repair ointment handles rough callus and can support fungus treatment. Both are effective but require patience — results aren't instant, and the foot ointment is pricier per ounce.
