Actinic cheilitis is cheilitis (lip inflammation) caused by long term sunlight exposure. Essentially it is a burn , [ 2 ] and a variant of actinic keratosis which occurs on the lip. [ 5 ] It is a premalignant condition , [ 6 ] as it can develop into squamous cell carcinoma (a type of mouth cancer ).
Actinic keratosis (AK), sometimes called solar keratosis or senile keratosis, [1] [2] is a pre-cancerous [3] area of thick, scaly, or crusty skin. [ 4 ] [ 5 ] Actinic keratosis is a disorder ( -osis ) of epidermal keratinocytes that is induced by ultraviolet (UV) light exposure ( actin- ).
Also termed "solar cheilosis", actinic cheilitis is the result of chronic over-exposure to ultraviolet radiation in sunlight. It usually occurs on the lower lip, which is dry, scaling, and wrinkled grey-white in appearance. [11]

Keratosis (from kerat-+ -osis) [1] is a growth of keratin on the skin or on mucous membranes stemming from keratinocytes, the prominent cell type in the epidermis. More specifically, it can refer to: actinic keratosis (also known as solar keratosis), a premalignant condition; chronic scar keratosis; hydrocarbon keratosis
Actinic elastosis, also known as solar elastosis, is an accumulation of abnormal elastin (elastic tissue) in the dermis of the skin, [2] or in the conjunctiva of the eye, [3] which occurs as a result of the cumulative effects of prolonged and excessive sun exposure, a process known as photoaging.

Photodermatoses is a skin condition resulting in abnormal skin reactions to ultraviolet (UV) radiation. [1] These abnormal skin reactions may develop into rashes. While reactions to UV radiation is common, true photodermatoses is considered when an abnormal reaction is caused by UV-A rays or radiation between 320 and 400 nm.
