How to Prevent Odor and Stay Fresh All Day: The Teen’s Real-World Guide
Why Odor Happens (and Why It’s Totally Normal)
Let’s be honest—body odor is just part of being human, especially if you’re a teen, you’re active, or both. Sweat itself doesn’t actually smell. It’s when sweat mixes with bacteria on your skin that things start to get funky. Hormones, stress, sports, and even what you eat can crank up the odor factor.
But here’s the good news: you don’t have to just “deal with it.” With a few smart moves and the right products, you can stay fresh, confident, and ready for anything—no matter how busy or sweaty your day gets.

The Science: What Causes Body Odor?
- Sweat + bacteria = odor. The bacteria that live on your skin love warm, damp places (like underarms, feet, and groin). When they break down sweat, that’s when the smell kicks in.
- Hormones: Puberty triggers your apocrine glands, which means more sweat and stronger odor.
- Clothes and gear: Tight, synthetic fabrics trap sweat and don’t let your skin breathe, making odor worse.
- Diet: Foods like garlic, onions, and spicy stuff can actually change your body odor.
The Ultimate All-Day Freshness Routine
1. Start Clean—Shower or Wash Daily
Kick off your day with a shower, especially after sports or before school. Use a gentle, natural cleanser that actually removes odor—not just covers it up.
Product tip:
Hydrating 2-in-1 Hair + Body Wash – Cleanses sweat and oil without drying out your skin.

2. Focus on the “Odor Zones”
Don’t just rinse—actually wash under your arms, feet, groin, and anywhere you sweat most. These are the spots where odor-causing bacteria love to hang out.
3. Dry Off Completely
Bacteria love moisture, so make sure you’re totally dry before putting on clothes—especially in skin folds and between your toes. Maybe try the Active Dry Powder to help with that crotch smell that is lingering after a long day.
4. Use a Natural Deodorant
A good deodorant doesn’t just mask odor—it helps prevent it by neutralizing bacteria. Bonus points if it’s aluminum-free, gentle, and designed for teen skin.
Try:
Prep U Natural Deodorant – Aluminum-free, available in scents like Big Sur, Solstice, and Surfside.

5. Choose Breathable, Clean Clothes
Wear loose, natural fabrics when you can (think cotton, bamboo). Change out of sweaty clothes and socks as soon as possible—don’t let them sit on your skin.
6. Keep Your Gear (and Shoes) Clean
Wash your workout clothes, towels, and gear after every use. Let your shoes air out and sprinkle a little powder inside if they’re starting to smell.
Product tip:
Talc-Free Moisture Wicking Active Dry Powder – Keeps feet and shoes dry and fresh.

- Pack a travel-size deodorant in your bag for after gym or practice.
