Shaving is among the most common grooming practices globally, but it causes superficial damage to the epidermal layer—manifesting as razor burns, erythema, micro-cuts, and localized inflammation. Aftershave preparations are designed to sterilize the skin, close pores, reduce irritation, and aid wound healing. However, conventional alcohol-based aftershaves often exacerbate dryness and irritation. Alum (potassium aluminum sulfate dodecahydrate) is a crystalline salt historically used as a styptic and deodorant. It remains popular in traditional markets for its proven skin-tightening and antiseptic effects [1]. Recent research renews its relevance as a sustainable and natural active for cosmetic formulations, particularly for aftershave gels and creams [2]. The astringent impact of protein precipitation at the cell's outer layer causes aluminum potassium sulfate (Alum) to reduce capillary permeability. Alum's ability to block sweat pores is very helpful for its antifungal action. By preventing sweat from escaping, it lowers the moisture content of the site of action, which inhibits the growth of fungal infections. Additionally, alum's antifungal activity also inhibits the growth and development of fungal infections, so it reduces fungal infections in two ways. Wintertime skin cracks are avoided since the alum powder dissolves in water. Because oily skin is more likely to result in pimples and acne, it has the power to dry the skin, which reduces the problem. [26]
