If your body odor changed after pregnancy, a new medication, or a shift in your cycle, you're not imagining it and you're not doing anything wrong. Hormones changed the sweat; the bacteria just responded to the new menu.

Why hormones change how you smell

Body odor comes from bacteria on your skin metabolizing the protein- and lipid-rich secretion from your apocrine glands — the ones concentrated in the underarm. Hormonal shifts (pregnancy and postpartum, perimenopause and menopause, your monthly cycle, certain medications) change the composition and volume of that secretion. Different input, different output: the bacteria produce a different, sometimes stronger, smell. It's a normal physiological response, not a hygiene failure.

What a deodorant can and can't do

A deodorant can't change your hormones — but it can handle the odor regardless of what's driving the sweat, by acting at the source where bacteria create the smell. That's the useful part: you don't have to wait out a hormonal phase to feel like yourself.

Why the formula matters more right now

Skin is often more reactive during these phases, especially postpartum. That's the worst time to be putting baking soda or heavy fragrance on your underarms. SENSITIVE is built for exactly this — baking-soda-free, fragrance-free, and clinically tested at 0% irritation, using the zinc-based BioShield™ system to eliminate odor at the source. If your sweat volume jumped, MAX is the heavier-duty option.

One honest note: if a change in body odor is sudden, dramatic, or comes with other symptoms, it's worth mentioning to your doctor — occasionally it signals something worth checking. But for the ordinary hormonal shifts of life, the fix is a gentle formula that works at the source.
