Uneven skin texture is usually the result of excessive accumulation of dead skin cells on the skin’s surface. It can make the skin appear rougher and greasy. Uneven skin may be rough, bumpy, dry, dull looking, and also big pores. Pores can be enlarged when dirt, oil, and/or debris become trapped. Also, both acne and sun damage plays a big role in uneven skin texture and pore-size irregularity. Some people are more prone to larger pores than others. Treatment is still possible for those prone to pore congestion.
