Pockmarks are small, crater-like depressions found on the surface of various materials, including soil, rock, and even skin. They are often formed by natural processes such as erosion, weathering, or the impact of meteorites. In geology, pockmarks can indicate past geological activity, such as gas or fluid escape from the seabed. In dermatology, pockmarks refer to scars left by conditions like acne or chickenpox. These scars can vary in size and depth, affecting the skin's texture. Treatments for pockmarks may include laser therapy, chemical peels, or fillers to improve the skin's appearance.
