Can you use alum to tighten your skin?

Alum, also called phitkari, can tighten skin, according to Herbpathy. Women in India have used alum for centuries as a tightening and lifting agent. It is a common ingredient in modern-day men's aftershave products and anti-aging creams, reports Wild Turmeric.

Alum is crystalline in its natural form, and you must dampen it to apply it to the skin. To apply alum to your body, wash the area you want to apply it to and pat it dry, leaving the skin moist. Thoroughly saturate the alum crystal with cold water, and spread it gently over the skin. Once the alum turns white and powdery, rinse the skin, and pat it completely dry, instructs Ygoy Health Community.
