Salkera emollient foam is a keratolytic foam containing 6% salicylic acid in an aqueous based emollient foam vehicle. It is different from other salicylic containing topical product in that it has been shown to produce desquamation of the stratum corneum while not effecting qualitative or quantitative changes in the structure of the viable dermis. In addition, it also contains aloe vera and anti-oxidants which help to sooth the skin. Salkera emollient foam has been used to treat several hyperkeratotic skin disorders such as KP, psoriasis, keratosis palmaris/plantaris, verrucae, icthyoses and pityriasis rubra pilaris. However, there has been no published study assessing the efficacy and safety of Salkera emollient foam in treating moderate to severe KP.
