Skin ages all over the body but much more so where there has been sun exposure. Changes brought on by sun damage (photoaging) include dryness (really roughness), sagginess, skin growths like keratoses, lentigos ( liver spots), and wrinkles.Most wrinkles associated with aging appear on the parts of the body where sun exposure is greatest.These especially include the hairless scalp, face, neck, the backs of the hands, and the tops of the forearms. Wrinkles come in two categories: fine surface lines and deep furrows.any products and procedures promise to reduce wrinkles. Some do little or nothing (like the products that claim they reduce the appearance of fine lines, which means that they don't reduce the lines themselves). Others can achieve a fair amount of success.
