Blackheads are typically more common for those living in humid environments, those with oily skin, or for people who use oil-based skincare products or sunscreens. Often, they are unavoidable. However, starting your skincare routine with a product designed to slough off dead skin cells and whisk away additional oils is a huge help in reducing blackheads.
Alpha-hydroxy acids like salicylic acid and glycolic acid have smaller molecule sizes than other skincare washes, thus allowing them to penetrate into pores, lift dirt, dead skin, and sebum out, then ferry it away. They can easily be used in conjunction with other cleansers for an effective double-cleansing routine.
