Sandpaper Skin is a dry rough skin condition. It is a pre-malignant skin condition.
Sandpaper Skin is common in elderly people. It is even found more frequently if they are often exposed to the sun’s UV rays.
Sandpaper Skin is medically called as Actinic keratosis (abbreviated AK for short) is also called solar keratosis or senile keratosis.

Sandpaper Skin is treated by a number ways as listed.
Sandpaper Skin is mostly caused by the damaging UV radiation of the sun rays.
The UV ray induces mutation of the keratinocyte cell and eventually cancer.
Cumulative sun exposure causes the AK. SPF 17 or more can significantly reduce incidence of AK.
Any history of sunburn is bad news. Even a single episode of sunburn can increase risk. Six or more times of sunburn can significantly increase incidence of AK. Balding is one of the main cause of AK on the scalp.
