Peeling Skin Syndrome (PSS) Market Outlook

Thelansis’s “Peeling Skin Syndrome (PSS) Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2025 To 2035” covers disease overview, epidemiology, drug utilization, prescription share analysis, competitive landscape, clinical practice, regulatory landscape, patient share, market uptake, market forecast, and key market insights under the potential Peeling Skin Syndrome treatment modalities options for eight major markets (USA, Germany, France, Italy, Spain, UK, Japan, and China).

Peeling Skin Syndrome (PSS) Overview

Peeling Skin Syndrome (PSS) is a group of rare autosomal recessive genodermatoses characterized by continuous shedding of the stratum corneum. It spans generalized non-inflammatory (Type A; CHST8), generalized inflammatory (Type B/PSS1; CDSN), and localized acral (APSS; TGM5 or CSTA) variants. Diagnosis relies on clinical phenotype, skin biopsies demonstrating splitting at the granular layer, and genetic sequencing. While historical management was strictly restricted to palliative emollients, the therapeutic paradigm has shifted toward targeted, genotype-specific interventions. For generalized inflammatory CDSN-mutated cohorts, the baseline has been transformed by QRX003, a first-in-class topical serine protease inhibitor lotion advancing into Phase 2 clinical evaluation. Concurrently, refractory systemic inflammation and pruritus are treated with the oral JAK1 inhibitor upadacitinib, which targets upregulated Th2-cytokine signaling (IL-4/IL-13). For localized APSS, management has expanded to incorporate repeated botulinum toxin type A injections to control hyperhidrosis, preventing the friction-induced epidermal cleavage that drives palmar and plantar exfoliation.
