Aloe vera has a long history of use in traditional medicine for various skin conditions, but its application for oily skin is also supported by emerging scientific evidence. Aloe vera gel contains polysaccharides, glycoproteins, vitamins, and minerals that contribute to its soothing and moisturizing properties without being comedogenic (i.e., it does not clog pores). Scientific studies indicate that aloe vera can reduce skin inflammation, accelerate wound healing, and provide a mild astringent effect, which can be beneficial for individuals with oily skin.

Several in vitro and clinical studies suggest that aloe vera has sebostatic properties, meaning it can help regulate the production of sebum—an oily substance produced by sebaceous glands. For example, a Journal of Dermatological Treatment study (2014) found that topical aloe vera, when used in combination with other agents, improved acne outcomes by reducing oiliness and inflammation. Aloe vera's antimicrobial activity may also help reduce the proliferation of acne-causing bacteria on oily skin. While more robust, large-scale clinical trials are needed to confirm these benefits, current evidence provides moderate support for the use of aloe vera in managing oily skin.

In summary, aloe vera is both traditionally and scientifically recognized for skin care benefits, and its use for oily skin is justified by moderate scientific evidence, particularly due to its non-greasy hydration, anti-inflammatory, and sebum-regulating effects.
