siiiba natural deodorant
Does this deodorant actually work?

Yes. Magnesium hydroxide and zinc oxide help neutralize the bacteria that cause odor.
Will this cause skin irritation?

Siiiba is HRIPT (Human Repeat Insult Patch Test) tested on sensitive skin and clinically evaluated for skin irritation and sensitization. All three scents passed testing with no product-related irritation, sensitization, or adverse events reported under study conditions.
What is HRIPT?

HRIPT stands for Human Repeat Insult Patch Test. It's a standard method for checking whether a product irritates or sensitizes skin over repeated use. Siiiba passed this testing across all three scents, with no product-related irritation, sensitization, or adverse events reported.
Why doesn't it have aluminum?

Aluminum-based compounds work by physically blocking sweat glands. That's effective, but it's also a lot to put on young, sensitive skin. Siiiba skips aluminum entirely and relies on odor neutralizers instead, a gentler approach better suited for developing bodies.
Is this suitable for my 8-year-old?

Yes. The formula is designed specifically for tweens and teens ages 8-16. Every ingredient is gentle and safe for sensitive skin, free of PFAS, aluminum, parabens, and synthetic dyes. If your child has a specific skin condition or allergy, check the full ingredient list with their doctor before use.
What does 'natural fragrance' mean?

Natural fragrance means the scent comes from plant-derived and nature-identical sources, not synthetic perfume compounds. The formula contains no phthalates or other fragrance chemicals of concern.
Will it stain clothes?

No. The formula doesn't contain aluminum, which is the primary culprit behind yellow pit stains. Apply to clean, dry skin and let it absorb for 30 seconds before dressing to avoid any white residue.
How is this different from adult natural deodorants?

Most adult natural deodorants use baking soda as a primary deodorizer. Baking soda is effective but frequently irritates young, sensitive skin. Siiiba uses magnesium hydroxide and zinc oxide instead, gentler ingredients that are better tolerated by tweens.
How long does one stick last?

With daily use (2-3 strokes per application), one 75g stick lasts approximately 8-10 weeks.
My son/daughter sweats a lot. Will this keep up?

Siiiba is a deodorant, not an antiperspirant. It stops odor, not sweat. Sweating is normal and healthy. If your child needs clinical-strength sweat control, speak with a pediatrician about appropriate options.
Is it cruelty-free?

Yes. Siiiba does not test on animals.
Where is it made?

Made in the USA.
Can this be used on other parts of the body?

This product is formulated for underarm use only.
How should it be stored?

Store at room temperature, away from direct heat or sunlight. High heat can soften the stick formula.
