What is the purpose of applying after shave?

The primary purpose of applying aftershave is to reduce redness and irritation caused by shaving. Shaving can strip the skin of natural oils and create micro-abrasions, which may lead to discomfort and inflammation. Aftershave products are often formulated with soothing ingredients that help calm the skin, reduce any razor burn, and promote healing.

While balancing the skin's pH is indeed important, aftershave specifically targets post-shave irritation and redness. Although some aftershaves may also have moisturizing properties and can contribute to preventing infections, the most direct effect relates to soothing the skin after the trauma of shaving. Therefore, focusing on reducing redness and irritation properly identifies the primary goal of aftershave application, making it the most relevant choice.
