Actinic Keratosis (AK) – Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2023 To 2033

Actinic keratosis (AK) is a prevalent skin lesion associated with prolonged exposure to ultraviolet (UV) radiation. These lesions typically manifest as scaly, red papules or plaques and represent the earliest clinically identifiable sign of squamous cell carcinoma (SCC). The development of actinic keratosis primarily results from the cumulative impact of UV radiation on the skin over a person's lifetime of sun exposure. The pathogenesis of actinic keratosis is intricate. Prolonged and excessive sun exposure to UV radiation can instigate pathological alterations in the epidermal keratinocytes, disrupting the regulatory pathways controlling cell growth and differentiation. This disruption leads to inflammation and immune suppression, fostering the intraepidermal proliferation of dysplastic keratinocytes, precursors to actinic keratosis. There are various clinical variations of actinic keratosis, including hyperkeratotic actinic keratosis, atrophic actinic keratosis, actinic cheilitis...
