Product Type taxonomy splits the Cold Sore Treatment market into three technology clusters. Topical formulations—creams, gels, ointments—secure the largest share owing to low cost, self-administration, and pharmacy shelf visibility, but growth is constrained by limited bioavailability. Oral antivirals (systemic tablets) command a price premium and exhibit faster revenue CAGR because physicians favour once-daily dosing to suppress recurrence, expanding the treated patient pool. Injectable interventions, though niche, generate per-unit sales spikes in hospital outbreaks or immuno-compromised cohorts, reinforcing brand equity for innovator manufacturers. Together, these segments shape the competitive arena and pricing hierarchy captured under Cold Sore Treatment segmentation analyses.
