Sodium Bicarbonate (baking soda)
Sodium Bicarbonate, also known as baking soda, is a natural mineral that plays a key role in keeping you fresh and confident all day. In our deodorant, it works by neutralizing odor-causing bacteria and balancing your skin’s pH—without the need for harsh chemicals or synthetic fragrances. Baking soda also helps absorb excess moisture, making it a safe and effective choice for active teens and sensitive skin. Trusted by parents and proven by science, Sodium Bicarbonate is one of the simplest, most reliable ways to fight body odor—naturally.
Caster Oil
This is the superstar of all oils in the clean beauty industry. It is rich in antioxidants, proteins, vitamin E, and unsaturated fats. It also absorbs easily and repeals water, which is very effective when locking in moisture. Castor oil is made from the bean of the Ricinus communis plant and is a thick warm, yellow consistency.
The overall benefits of caster oil include:
• Antibacterial properties to help fight bacteria that lead to acne
• Moisturizes the skin
• Promotes overall skin health
Jojoba Oil (Simmondsia Chinensis)
This fantastic oil has natural anti-bacterial and anti-fungal properties not to mention it is great on the face and body. Super hydrating, full of nutrients, vitamins, and minerals. This oil acts like our own sebum. Jojoba oil also has high amounts of iodine, which fights bacterial growth. And given our pits have very thin skin, which is prone to dryness and bacteria, this was a no-brainer ingredient that we had to have in our products.
The overall benefits of Jojoba Oil include:
• Deeply Hydrating
• Moisturizes
• Nutrients for the skin - full of vitamins E and B
• Anti-Microbial -- Naturally deters microbes which helps prevent the growth of bacteria on the skin
• Gentle on all skin types - especially skin types that are sensitive
Virgin Coconut Oil (Cocos Nucifera)
This magical elixir is made from the white fleshy part of the coconut. It is refined down to an oil, which is solid at room temperature but when heated up will turn back to a liquid form. The benefits of coconut oil are that it hydrates the skin. It is made up of fatty acids that help reduce dryness and allow your skin to retain moisture. It helps protect the skin giving your skin that protective barrier against environmental pollutants. Coconut oil also improves the texture of your skin over time. It absorbs easily into the skin and soothes irritated skin.
The overall benefits of coconut oil include:
• Locking in hydration - coconut oil helps your skin’s protective barrier layer which traps moisture in the skin
• Provides antioxidants
• Absorbs easily
Shea Butter (Butyrospermum Parkii)
Our plant-based deodorant is made with Shea Butter. Shea Butter is made from the nuts of a shea tree and is native to West Africa. It has a high concentration of fatty acids and vitamins. Shea is safe for all skin types and doesn’t contain chemical irritants known to dry out the skin. It doesn't clog pores. There are many reasons why we used Shea Butter; Its anti-inflammatory properties trigger cells to slow their production. This has high levels of vitamins A & E, which promote healthy skin. Shea tree products are widely known for their anti-fungal properties.
The overall benefits of Shea Butter include:
• Boosts skins moisture
• Anti-inflammatory properties soothe skin issues
• Helps fight breakouts and blemishes
• Softens dry skin
Arrowroot (Maranta Arundinacea)
Did you know that arrowroot is packed full of materials and vitamins such as zinc, iron, potassium, and vitamin B6? This makes this a perfect ingredient to provide relief from skin irritations such as rashes, acne, and skin sores. We used this as a substitute for talc and cornstarch in our products. It is similar to cornstarch, but it is finer and less irritating to the skin.
The overall benefits of Arrowroot include:
• Contains NO Gluten
• Packed with Vitamen-B
• The new Baby Powder Alterative -- contains no talc!
Magnesium Hydroxide
Magnesium Hydroxide is a gentle, naturally-derived mineral that helps neutralize odor without blocking pores or irritating sensitive skin. In our deodorant, it works by balancing your skin’s pH and stopping odor-causing bacteria—offering lasting freshness with a clean, safe approach for teens and young adults.
Zinc Oxide
Zinc Oxide is a naturally-derived mineral that helps fight odor and soothe sensitive skin. In our deodorant, it works by neutralizing odor-causing bacteria and calming irritation—without clogging pores or using harsh chemicals. It’s a gentle, effective way to keep you feeling fresh and protected all day.
Tocopherols (Vitamin E)
Vitamin E is a powerful antioxidant that helps protect and soothe your skin. In our deodorant, it nourishes delicate underarm skin, supports healing, and adds a layer of gentle care—keeping you comfortable, fresh, and confident all day.

- Perfect for sensitive skin and growing teens

The Best Clean Natural Deodorant—EWG Verified for Your Safety
Prep U’s natural deodorant is EWG VERIFIED™, so you can trust it’s free from hazardous chemicals like phthalates, parabens, and triclosan. These ingredients are linked to serious health concerns, but we keep them out—always. With Prep U, you know exactly what’s in your deodorant: safe, transparent, and effective care for teens and young adults.
Antiperspirant vs. Deodorant
Deodorant and antiperspirant aren’t the same! Deodorants (like Prep U) fight odor by stopping the bacteria that cause smells, while antiperspirants block sweat itself. Fun fact: sweat doesn’t actually smell—odor happens when it mixes with skin bacteria. So you can stay fresh and confident, naturally, without blocking your body’s natural process.

FAQs
How long does your stick of deodorant last?
Most people find Prep U provides all-day odor protection—even for active teens and athletes. For best results, apply to clean, dry skin after showering.
What if my deodorant melts or is too hard to apply?
No worries—natural deodorant can change texture with heat or cold, but it’s easy to fix!
- If it’s too soft or melted: Turn the stick upside down and pop it in the fridge. It’ll firm up and settle back into place. Our deodorant topper’s protective seal also helps prevent leaks.
- If it’s too hard: Hold the stick against your skin for about a minute to warm it up. It’ll soften and glide on smoothly.
