Background
Acne, also known as acne vulgaris, is a condition of long-term occurrence of blackheads, whiteheads (white or milky white broken rice-shaped acanthopapules), whelks, oily skin, or scars on the skin; most people have experience with growing comedones, and many people deal with them by pressing their fingers against the affected part to press the pimples or pus from the hair follicles, however, the fingers of people often carry many germs (especially nail cracks) and the skin surface has many germs, and if the fingers are pressed directly without being cleaned, the skin is easily infected, and the skin becomes inflamed or even cellulitis.
Therefore, there are many devices on the market to replace fingers to squeeze or remove comedones, such as a device commonly called a acne stick or a youth stick, which mainly uses a ring to squeeze the affected part to generate an even pressure around the affected part to press out comedones or bloody pus from hair follicles, such a device sometimes cannot squeeze out comedones completely, the purulent substance remains in the skin for a long time to form severe acne, and even if it subsides slightly, it leaves a black head in the skin, if the person has much subcutaneous fat, the skin after red swelling is difficult to be folded up to form the squeeze of the comedones due to the small volume of the comedones, and if the skin is not disinfected in time during the squeezing process, inflammation or cellulitis likely to occur at the affected part.
