Introduction: Why Deodorant Is No Longer “Just Deodorant”.
Deodorant has officially entered its skincare era and honestly, it was long overdue. For years, most of us accepted deodorants that either masked odor with heavy fragrance or blocked sweat altogether with aluminum-based ingredients. They did the bare minimum, and often left behind irritation, clogged pores, ingrown hairs, and discoloration. As someone who has become far more ingredient-conscious in my late 30s, I’ve realized that underarm care deserves the same attention as facial skincare.
At 38 years old, with mature combination skin that’s also slightly acne-prone, I’m incredibly selective about what I put on my body. During the cooler months, my skin leans dry and my eczema has a tendency to flare, especially in sensitive areas like the underarms. That’s why I’ve gravitated toward skincare-forward deodorants over the years, and why Truly Beauty has remained a staple brand in my routine.
If you’ve followed my beauty journey for any length of time, you know this already. I’ve been using Truly Beauty products for years, and I’ve quite literally tried everything they make. Body butters, shaving products, serums, tools, facial skincare, deodorants, merch, you name it. Every time Truly launches something new, I’m one of the first people in line to try it. So when I heard they were launching a Soft Serve Serum Deodorant, I didn’t hesitate.
What makes this launch especially exciting is that it’s Truly Beauty’s first serum roll-on deodorant, and it features the iconic Soft Serve fragrance, a strawberry sundae-inspired scent that has become wildly viral for a reason. This product doesn’t just smell amazing. It’s packed with 5% AHA, vitamin C, and niacinamide, making it a true hybrid between skincare and deodorant.
In this review, I’m breaking down everything you need to know from the science behind AHA deodorants to my real-world experience using it daily. If you’re looking for a clean, aluminum-free deodorant that actually works, this one deserves your attention.
Truly Beauty: The Brand That Redefined Clean, High-Performance Body Care.
Truly Beauty isn’t just another trendy body care brand, it’s a company that has fundamentally changed how we think about clean beauty. Since its early days, Truly has focused on merging luxury-level performance with vegan, clean formulations, and that philosophy is woven into every product they create.
What sets Truly Beauty apart is their refusal to compromise. Many clean beauty brands lean heavily into “natural” while sacrificing effectiveness. Truly took the opposite approach. They worked with physicians, microbiologists, and world-renowned chemists to prove that vegan, clean formulations can perform just as well, if not better than traditional beauty products.
Truly Beauty’s product range is impressively expansive. They create body care products, facial skincare, skincare tools, hair care, deodorants, and even merch, all designed to feel indulgent while delivering real results. Over the years, they’ve also become known for launching cohesive product lines centered around specific skin concerns and signature fragrances.
Another major reason Truly has earned such a loyal following is their commitment to being not your average clean beauty brand. Their products are playful, visually iconic, and trend-driven yet still grounded in serious skincare science. This balance of fun and function is exactly why so many of their launches go viral on TikTok and Instagram.
The Soft Serve line is a perfect example of this ethos. It combines nostalgic, dessert-inspired fragrance with high-performance skincare ingredients and the new Soft Serve Serum Deodorant fits seamlessly into that universe.
Product Overview: Meet the Soft Serve Serum Deodorant.
The Truly Beauty Soft Serve Serum Deodorant is a brand-new launch, and it represents a major evolution in Truly’s deodorant lineup. Unlike their original Coco Cloud and Unicorn Fruit stick deodorants, this formula is a lightweight serum roll-on designed to treat the underarms like skincare not just cover odor.
At the core of this deodorant is 5% AHA, a potent yet gentle blend of lactic acid and mandelic acid. Instead of masking odor or blocking sweat, this formula targets odor at its source by lowering the skin’s pH and eliminating odor-causing bacteria. The result? Long-lasting freshness without interfering with your body’s natural sweat process.
What makes this deodorant especially exciting is its ability to brighten underarm discoloration, smooth texture, and reduce ingrown hairs all while keeping you smelling incredible. It’s clean, aluminum-free, baking soda–free, and suitable for daily use.
Despite its advanced formulation, it’s also refreshingly affordable, making it accessible without sacrificing quality. The sleek, compact packaging makes it perfect for tossing into a purse, gym bag, or carry-on, and yes, it’s TSA-approved at 50 ml, which is a huge plus for travelers.
And of course, we can’t talk about this product without mentioning the scent. If you love the Soft Serve line, you already know: strawberry, vanilla, and amber blended into a mouthwatering strawberry sundae fragrance that lingers just enough to feel indulgent, never overpowering.
Key Ingredients & Benefits: Why This Formula Actually Works.
Truly Beauty didn’t hold back when it came to ingredients. This deodorant is thoughtfully formulated to protect, prevent, treat, and nourish the underarm skin.
5% AHA (Lactic Acid + Mandelic Acid).
This powerful AHA blend works by lowering the skin’s pH, making it inhospitable to odor-causing bacteria. Lactic acid gently exfoliates dead skin cells while hydrating the skin, and mandelic acid helps regulate oil production and prevent clogged pores, which is key for reducing ingrowns and bumps. Together, they smooth texture, combat odor, and minimize discoloration over time.
Vitamin C (3-O-Ethyl Ascorbic Acid).
Vitamin C is a proven brightening powerhouse. In this formula, it helps fade underarm discoloration, improve overall skin tone, and protect against environmental stressors. With consistent use, underarms appear more even, radiant, and healthy-looking.
Niacinamide.
Known for its anti-inflammatory and barrier-strengthening properties, niacinamide helps calm irritation, reduce redness, and visibly brighten the skin. It’s especially beneficial for sensitive or eczema-prone skin, making this deodorant surprisingly gentle despite its active ingredients.
Panthenol & Glycerin.
These humectants help maintain hydration and comfort, preventing dryness or tightness, a crucial detail for mature skin types and those prone to irritation.
My Experience: A Long-Time Truly Beauty Lover Tries the Soft Serve Serum Deodorant.
Having used Truly Beauty deodorants on and off for years, I already knew what to expect in terms of fragrance and overall vibe. What surprised me most about the Soft Serve Serum Deodorant was how quickly it became a daily essential.
The texture is silky and lightweight, gliding on effortlessly without tugging at the skin. Within about 30–60 seconds, it dries down completely, no stickiness, no residue, and absolutely no white marks on clothing. That alone puts it miles ahead of many natural deodorants I’ve tried in the past.
Performance-wise, it genuinely keeps me fresh all day. I don’t feel wet, sticky, or uncomfortable, even on long, busy days. And because it doesn’t block sweat, my underarms feel healthier, not congested or irritated.
One of the biggest wins for me has been how it handles razor burn and ingrown hairs. I’ve noticed significantly smoother underarms with less irritation after shaving, which is something I don’t often get from deodorants.
As someone who rotates Truly Beauty products depending on the scent family I’m using, this deodorant fits perfectly into my Soft Serve routine. The scent layers beautifully with other products from the line and lasts just long enough to feel luxurious.
Exploring the Soft Serve Line: Truly Beauty’s Most Iconic Collection.
The Soft Serve line has become one of Truly Beauty’s most viral collections and for good reason. Inspired by dessert nostalgia and infused with high-performance skincare ingredients, it delivers results while feeling indulgent and fun.
From body butters to body oils and serums, the Soft Serve line is all about hydration, glow, and scent layering. The strawberry vanilla fragrance is instantly recognizable and deeply comforting, making it easy to build a cohesive body care routine that feels elevated.
Adding the Soft Serve Serum Deodorant to this lineup was a natural next step. It completes the routine, ensuring that every layer of your body care, from cleansing to hydration to odor protection, works together seamlessly.
Final Thoughts: Is the Truly Beauty Soft Serve Serum Deodorant Worth It?
After weeks of consistent use, I can confidently say that the Truly Beauty Soft Serve Serum Deodorant is one of the most impressive deodorant launches I’ve tried in years. It doesn’t just cover odor, it treats the skin, improves texture, and supports long-term underarm health.

Frequently Asked Questions: Truly Beauty Soft Serve Serum Deodorant.
What is the Truly Beauty Soft Serve Serum Deodorant?
The Truly Beauty Soft Serve Serum Deodorant is a clean, aluminum-free AHA deodorant designed to target body odor at its source rather than simply masking it. Unlike traditional stick deodorants, this formula uses a lightweight serum texture that glides on smoothly and dries quickly without leaving residue. It contains 5% AHA (lactic acid and mandelic acid) to neutralize odor-causing bacteria while also smoothing texture, brightening discoloration, and helping prevent ingrown hairs. It’s part of Truly Beauty’s viral Soft Serve line and features the iconic strawberry vanilla scent.
How does an AHA deodorant work?
AHA deodorants work by lowering the skin’s pH, creating an environment where odor-causing bacteria cannot thrive. Instead of blocking sweat glands like traditional antiperspirants, AHAs gently exfoliate the skin and reduce bacterial buildup that causes body odor. The Soft Serve Serum Deodorant uses lactic acid and mandelic acid to exfoliate dead skin cells, smooth underarm texture, and keep odor under control naturally, all while allowing your body to sweat normally.
What makes the Soft Serve Serum Deodorant different from regular deodorants?
Traditional deodorants often rely on fragrance to mask odor or aluminum salts to block sweat. The Truly Beauty Soft Serve Serum Deodorant takes a skincare-first approach. It treats the underarms with active ingredients like AHAs, vitamin C, and niacinamide, which means it doesn’t just control odor, it also improves skin tone, texture, and overall underarm health. It’s lightweight, residue-free, and designed to feel more like a serum than a deodorant.
Does this deodorant stop sweating?
No, and that’s intentional. The Soft Serve Serum Deodorant is not an antiperspirant, so it does not block sweat glands. Instead, it focuses on eliminating odor-causing bacteria while allowing your body to sweat naturally. Many people find this approach more comfortable and less irritating, especially if they have sensitive skin or experience clogged pores from traditional antiperspirants.
Is the Soft Serve Serum Deodorant safe for sensitive skin?
The formula is aluminum-free, baking soda-free, and designed to be gentle, but because it contains active exfoliating acids, it’s always best to patch test first, especially if you have sensitive skin. If you have mild eczema or easily irritated underarms, start with once-daily use and monitor how your skin responds. Avoid using on broken skin, immediately after shaving, or during an active eczema flare.
Can this deodorant help with underarm discoloration?
Yes. One of the standout benefits of this deodorant is its ability to visibly brighten underarm discoloration over time. The combination of vitamin C, niacinamide, and gentle AHAs helps exfoliate dead skin cells, promote cell turnover, and improve uneven skin tone. With consistent daily use, many users notice brighter, more even-looking underarms within a few weeks.
Does it help prevent ingrown hairs and razor burn?
Absolutely. The exfoliating action of lactic acid and mandelic acid helps keep pores clear and smooth, which reduces the likelihood of ingrown hairs after shaving. Additionally, soothing ingredients like niacinamide and panthenol help calm irritation and razor burn, making this deodorant especially helpful for those who shave regularly.
How long does the Soft Serve Serum Deodorant last throughout the day?
The deodorant starts working immediately after application and keeps you smelling fresh for hours by targeting odor-causing bacteria. Many users notice effective odor control from the very first use. For best results, apply once daily to clean, dry underarms and allow it to fully dry before getting dressed.
How long does it take to see results?
You’ll notice odor control right away, but skincare benefits like smoother texture and brighter underarms develop over time. Most people begin seeing visible improvements in discoloration and ingrown hairs within 2–4 weeks of consistent daily use.
What does the Soft Serve Serum Deodorant smell like?
It features the signature Soft Serve fragrance, which smells like a strawberry sundae with creamy vanilla and warm amber notes. The scent is sweet, nostalgic, and luxurious without being overpowering. It's perfect for layering with other Soft Serve products.
Is this deodorant travel-friendly?
Yes! The Soft Serve Serum Deodorant comes in a 50 ml roll-on bottle, making it TSA-approved and perfect for travel, gym bags, and purses. Its compact size makes it easy to reapply on the go if needed.
How do I use the Soft Serve Serum Deodorant?
Apply generously to clean, dry underarms. Allow the serum to dry for 30–60 seconds before getting dressed to prevent transfer. For best results, use daily as part of your body care routine.
Who should avoid using this deodorant?
If you have open wounds, severe eczema flares, or known sensitivities to AHAs, it’s best to avoid use or consult a dermatologist first. Always discontinue use if irritation occurs.
Is the Truly Beauty Soft Serve Serum Deodorant clean and vegan?
Yes. Like all Truly Beauty products, this deodorant is vegan, cruelty-free, and clean, formulated without aluminum or parabens. Truly Beauty is known for combining high-performance ingredients with clean beauty standards.
Can I use this deodorant with other Truly Beauty products?
Definitely. The Soft Serve Serum Deodorant pairs perfectly with other products from the Soft Serve line, allowing you to layer scent and maximize results across your entire body care routine.
Is the Truly Beauty Soft Serve Serum Deodorant affordable?
Yes, especially compared to many luxury deodorants with similar skincare benefits. Plus, my audience can use my exclusive discount code to save even more when shopping Truly Beauty, making it an even better value.
