For centuries, alum has been a trusted skincare secret passed down through generations in Pakistani households. This natural mineral, known locally as “phitkari,” offers remarkable alum benefits for skin that modern beauty products often struggle to match. From treating stubborn acne to tightening loose skin, alum works wonders without burning a hole in your pocket.
According to the U.S. Food and Drug Administration (FDA), potassium alum is classified as a “Generally Recognized as Safe” (GRAS) substance for use in food and cosmetic products. The Environmental Working Group (EWG) also rates potassium alum with a low toxicity score for cancer risk, allergies, and developmental concerns. This makes it a relatively safe natural skincare option when used correctly.
Many people are now turning back to this traditional remedy after trying countless expensive creams and treatments. Alum is easily available at any local store and costs next to nothing. However, before you start using it, understanding how it works and the right way to apply it makes all the difference.
What is Alum?
Alum is a naturally occurring mineral compound, scientifically known as potassium aluminum sulfate (KAl(SO₄)₂·12H₂O). It comes in the form of a white crystalline block or powder. According to DrugBank, potassium alum forms large molecules that cannot be absorbed through the skin when used topically.This contributes to its safety profile for external use.
People have used alum for various purposes including water purification, aftershave treatment, and most importantly, skincare. This mineral has strong astringent and antibacterial properties. This makes it particularly useful for those dealing with oily skin, acne, and other common skin problems.
Top 6 Alum Benefits for Skin Health
1. Controls Excess Oil
Oily skin can be frustrating, especially in Pakistan’s humid weather. Alum benefits for skin include its natural astringent action that causes tissues to contract and tighten. When applied correctly, it reduces oil production and keeps your face fresh and shine-free for hours.
2. Fights Acne and Pimples
As per a laboratory study, alum exhibits antibacterial activity against Staphylococcus aureus, one of the bacteria commonly associated with skin infections. With acne impacting about 85% of adolescents and young adults worldwide, natural options like alum are gaining popularity for skin care.
3. Reduces Dark Spots and Pigmentation
Among the notable alum benefits for skin is its ability to help lighten dark spots, acne marks, and uneven skin tone over time. It gently exfoliates the skin surface, encourages new cell growth and gives you a more even complexion.
4. Tightens Skin Naturally
Looking for a natural anti-aging solution? Alum tightens loose skin and minimizes the appearance of fine lines. According to Medical News Today, alum’s astringent properties cause the skin to contract, temporarily reducing the size of pores and giving skin a tighter appearance. Many women use alum water as a natural toner to maintain firm, youthful-looking skin.
5. Heals Minor Cuts and Wounds
Alum has natural antiseptic qualities that help heal small cuts, razor burns, and nicks. A research study confirmed that potassium aluminum sulfate inhibits the growth of malodor-producing skin flora. This is why barbers have traditionally used alum blocks after shaving to prevent infections and soothe irritated skin.
6. Works as Natural Deodorant
Unlike many commercial deodorants, alum does not clog pores or interfere with the body’s natural cooling process. Its bacteriostatic properties help prevent bacterial growth. This makes it an effective and chemical-free alternative for odor control.
How to Use Alum for Skin
Using alum correctly is essential to avoid any irritation. Here are some safe methods:
As a Toner:
Dissolve a small piece of alum in water and let it sit overnight. Use this alum water as a toner after washing your face. It tightens pores and controls oil. Research indicates that an optimal pH of around 5.5 should be maintained, which alum-based toners can help achieve.
For Acne Treatment:
Wet the alum block slightly and rub it gently on affected areas. Leave it for 5-10 minutes and rinse with cold water. Do this once daily for best results.
As a Face Pack:
Mix alum powder with multani mitti (fuller’s earth) and rose water to form a paste. Apply on your face, let it dry, and wash off. This combination works wonders for oily and acne-prone skin.
Side Effects of Alum on Skin
While alum benefits for skin are impressive, using it incorrectly can cause problems:
- Skin dryness if used excessively
- Burning sensation on sensitive skin
- Irritation or redness
- Allergic reactions in rare cases
The Environmental Working Group (EWG) notes that while concerns exist about long-term aluminum exposure, the evidence remains insufficient and potassium alum receives a low overall hazard score.
Note: Always do a patch test before applying alum on your face. If you experience any discomfort, stop using it immediately and consult a dermatologist.
Tips for Safe Use
- Never apply alum on broken or wounded skin.
- Limit use to 2-3 times per week.
- Always moisturize after using alum to prevent dryness.
- Avoid leaving alum on skin for too long.
- Use pure, food-grade or cosmetic-grade alum for best results.
