Xerosis, UV-related skin disorders (tanning, photomelanosis, acute and chronic sunburn, polymorphic light eruption, chronic actinic dermatitis, actinic cheilitis, etc.), cold injuries (frostbite, chilblains, acrocyanosis, erythrocyanosis, etc.) nail changes (koilonychias), airborne contact dermatitis, insect bite reaction, and skin carcinoma (basal cell carcinomas, squamous cell carcinomas, and also rarely malignant melanoma) are the dermatoses seen in high altitude areas.

@jaspreet Tanning, photomelanosis, acute and chronic sunburn, polymorphic light eruption, chronic actinic dermatitis, actinic cheilitis are common photo-dermatoses of this region caused by abnormal cutaneous reactions to solar radiation. While these diseases have different pathophysiologic mechanisms, not all of which have been clearly defined, photoprotection is an integral part of their management. The intensity of UV is maximum between 10 a.m. and 3 p.m. Although both UVA (320–400 nm) and B (280–320 nm) are harmful to the skin, it is the UVB component that is responsible for acute skin damage
