Which method is not recommended for preventing skin irritation after shaving?

Rubbing alcohol directly on the skin is not recommended for preventing skin irritation after shaving because it can disrupt the skin's natural barrier. While alcohol can provide a temporary feeling of cleanliness and can help disinfect small cuts, it can also lead to excessive dryness, stinging, and irritation. This is particularly problematic after shaving, as the skin is already sensitive and may have micro-cuts from the razor.

In contrast, applying aftershave products designed to soothe and hydrate, using a hot towel to open pores and prepare the skin, and moisturizing with lotion are all strategies aimed at calming the skin post-shave. These practices help replenish moisture, maintain skin health, and reduce the risk of irritation, making them more suitable choices for aftercare.
