Efficacy and Safety of Salkera Emollient Foam in the Treatment of Moderate to Severe Keratosis Pilaris, a Prospective Study
Keratosis pilaris (KP) is a benign, inherited skin disorder that presents as grouped, rough,
horny follicular papules. It is estimated that 40-50% of the adult population and 50-80% of
adolescents suffer from KP. Both men and women are affected, with a possible female
predominance. It is noted worldwide and shows no racial predilection. Most patients with
KP are actually unaware that the condition has a designed medical term. Although no clear
etiology had been identified, KP is sometimes associated with other skin conditions such as
icththyosis vulgaris, xerosis or atopic dermatitis.
Many patients with KP never seek medical attention since they are asymptomatic. However, KP
can create significant cosmetic concerns in some cases. It can also become symptomatic
especially when inflammatory lesions are present. There is no gold standard treatment for
KP. Prevention of excessive dryness of the skin and continued moisturization are used
currently as standard of care. Many topical agents such as tretinoin, ammonium lactate
lotion, urea creams, tazarotene, adapalene, tacrolimus, alpha hydroxy acids and salicylic
acids have been used with variable results. Sometimes topical corticosteroids are used,
especially when inflammation is present. In general, KP treatments need to be continuous
and complete clearance may not be possible.
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.
This prospective single center pilot study is designed to assess the efficacy and safety of
Salkera emollient foam in treating moderate to severe KP. Patients' cosmetic acceptance of
the product will also be assessed. In addition, this study is also designed to develop a
validated outcome measure for assessing KP severity that can be used in future KP clinical
trials.
