What is alum primarily used for in skincare?

  1. Astringent and antiseptic properties

  2. Moisturizing and softening skin

  3. Promoting healthy tissue growth

  4. Reduces puffiness around the eyes

The correct answer is: Astringent and antiseptic properties

Alum is primarily recognized for its astringent and antiseptic properties, making it a beneficial ingredient in various skincare products and treatments. Astringents help to tighten and tone the skin, which is particularly useful for individuals with oily or acne-prone skin. The antiseptic qualities of alum assist in preventing infections and reducing inflammation, which can contribute to clearer skin. Although alum can have other effects, such as mild cooling sensations that might temporarily reduce puffiness, its main therapeutic applications are linked to its ability to act as an astringent and antiseptic. This makes it a popular choice in formulations aimed at managing excess oil and preventing breakouts, as well as in aftershave products and other treatments that aim to maintain skin cleanliness.
