Beauty by Earth Aluminum-Free Magnesium Deodorant Stick Review & Deal

Beauty by Earth's magnesium deodorant in Feel Good Citrus is down to $14.20 with Subscribe & Save — here's whether it's worth adding to your routine.

What magnesium deodorant actually does (and doesn't do)

Beauty by Earth's stick uses magnesium instead of aluminum to neutralize odor-causing bacteria. That's an important distinction: this is a deodorant, not an antiperspirant, so you'll still sweat. If you're switching from a clinical-strength product, expect a short adjustment period while your body recalibrates. The Feel Good Citrus scent is light and not aggressively perfumed — more like a clean citrus than a cologne counter. The 2.65-oz stick is a standard travel-friendly size, not a jumbo, so you'll go through it in a month or two of daily use.

Who the Subscribe & Save price makes sense for

At $14.20 via S&S, this lands in reasonable territory for a clean-ingredient deodorant — comparable brands often run $15–18 at retail. The catch is you're committing to recurring deliveries to lock in that price, so it suits people who've already tried magnesium deodorant and liked it more than someone curious to experiment. If you're new to aluminum-free options, it might be smarter to buy one at full price first to test how well it works for your body chemistry before setting up a subscription.
