Can alum be use to tighten face skin safely?

While some people claim that using alum can help tighten facial skin, there is limited scientific evidence to support this. Additionally, using alum on the skin can be potentially harmful. Alum is a mineral composed of potassium aluminum sulfate, and when used in high concentrations, it can cause irritation, dryness, and allergic reactions. It can also disrupt the skin's natural pH balance, making it more susceptible to damage from environmental factors such as sun exposure.

If you are looking for ways to tighten your facial skin, there are safer and more effective methods available, such as using skincare products that contain ingredients like retinol, vitamin C, and hyaluronic acid; incorporating a regular skincare routine that includes cleansing, moisturizing, and sun protection; and considering professional treatments like laser therapy or microneedling. It's always best to consult with a dermatologist or skincare professional before trying any new skincare remedies.
