Oily skin is the skin type most prone to acne due to the increased production of sebum, which is an oily substance produced by sebaceous glands. When the skin produces excess sebum, it can lead to clogged pores, creating an environment that is conducive to the growth of acne-causing bacteria. This excess oil can mix with dead skin cells and other debris, further exacerbating the risk of breakouts.

Additionally, individuals with oily skin often experience larger and more visible pores, which can easily become blocked. This is why effective acne treatment often includes products that can help regulate sebum production and reduce clogged pores.

Other skin types, such as dry, combination, and sensitive skin, may experience acne as well, but typically to a lesser degree than oily skin. While combination skin can have both oily and dry areas, and sensitive skin may react to certain products, those factors usually do not contribute to acne as significantly as the sebum overproduction associated with oily skin. Understanding the characteristics of different skin types helps in choosing the right skincare products and treatments to manage acne effectively.
