POTASSIUM ALUM
Is POTASSIUM ALUM safe for seborrheic dermatitis?
Evidence is too limited to rate Potassium Alum confidently for seborrheic dermatitis. It is used for an astringent or deodorising effect and has no established role in treating seb derm.
Potassium Alum is an inorganic salt rather than a fatty nutrient for Malassezia, but that does not guarantee comfort on inflamed skin. Astringent salt products can sting, especially after shaving or on cracked areas, and no direct human seb derm evidence was found. Use only as directed and stop if it repeatedly causes burning, dryness or redness.

What is POTASSIUM ALUM used for in skincare?
Potassium Alum is a crystalline double sulfate salt of potassium and aluminium. In personal care it is used mainly for its astringent and deodorant properties rather than for moisturising or barrier support. It is most often found in crystal deodorants, aftershave products and specialty powders, sometimes with water, humectants or fragrance.
