Systemic agents, such as oral anti‑inflammatory drugs and immunomodulators, target broader inflammatory pathways and account for approximately 20% of sales, reflecting their niche use in severe cases. Physical modalities—including laser therapy, photobiomodulation, and specialized dressings—provide non‑pharmacologic options, representing about 25% of the market, driven by clinical preference for adjunctive care. Combination therapies integrate two or more of the aforementioned approaches, delivering synergistic benefits and capturing the remaining 10% of market share.
