Final answer:
Using an astringent typically tightens and dries the skin, which can lead to irritation and a stinging sensation. Alcohol-free products are preferred to prevent these side effects, especially in products like aftershave balms that moisturize. Ingredients that alleviate itching and inflammation are commonly found in moisturizing creams and are beneficial for skin conditions like eczema.
Step-by-step explanation:
Applying an astringent on the skin typically leads to tightening and drying effects, due to the contraction of skin cells and pores. A stringents often contain antiseptic agents like denatured alcohol, stearate citrate, or witch hazel, which help to reduce skin irritation and prevent infection, especially of any cuts that might occur during shaving. However, these ingredients can also cause a stinging sensation and remove natural oils, leading to skin dryness. To combat possible negative reactions, it is recommended to use alcohol-free products, especially in the form of aftershave balms during colder months, as these are more like lotions and help to moisturize the skin rather than drying it out.
Moisturizing creams, on the other hand, are expected to contain substances such as natural oils, glycerin, or ceramides, which possess properties that replenish moisture, alleviate itching, and reduce inflammation of the skin. Furthermore, patients with the eczema skin condition, which can cause rash-like symptoms, should avoid harsh chemicals and substances that could irritate their skin further. Instead, they should opt for products that contain ingredients supportive of skin health, like moisturizers and substances that help maintain the elasticity of the skin, such as elastin fibers.
