Which ingredient is most commonly found in products targeting oily skin?

Salicylic acid is a beta hydroxy acid (BHA) that is particularly effective for treating oily skin. This ingredient works by deeply penetrating the pores to exfoliate the skin and help dissolve the excess sebum, dead skin cells, and other debris that can lead to clogged pores and acne breakouts. Its anti-inflammatory properties also make it suitable for managing and reducing the inflammation often associated with acne.

In contrast, ceramides are lipids that help restore the skin barrier and retain moisture, making them more beneficial for dry or sensitive skin rather than oily skin. Glycerin is a humectant that draws moisture into the skin, which is helpful for hydration but does not directly address issues related to oil production. Shea butter is a rich emollient that provides nourishment and moisture, generally more suited for dry skin types due to its heavier texture. Therefore, salicylic acid stands out as the primary ingredient for oily skin care products aimed at controlling oiliness and preventing acne.
