Use: Labeled Indications

Hyperkeratotic conditions: Debridement and promotion of normal healing of hyperkeratotic surface lesions, particularly where healing is retarded by local infection, necrotic tissue, fibrinous or purulent debris, or eschar; treatment of hyperkeratotic conditions, such as dry, rough skin; skin cracks and fissures; dermatitis; psoriasis; xerosis; ichthyosis; eczema; keratosis; keratoderma; corns and calluses; damaged, ingrown, and devitalized nails.
