BY YAN ReviewNo-appointment French Perfume Lab: AI Decodes Your Signature Scent

When it comes to perfume, many people immediately think of Grasse, France, the "perfume capital of the world." But now, you don't need to fly to France to embark on an olfactory journey; you can experience authentic Taipei Perfume Blending right here in Dazhi, Taipei. BY YAN has exclusively introduced the official French perfume system from the Grasse Institute of Perfumery, bringing centuries of traditional blending craftsmanship directly into a department store setting.

This Taipei Perfume Blending experience is far more than a casual "sniff-and-go"; it's a deep dive into the art of fragrance. You'll personally engage in the entire process, from identifying individual raw materials to layering complex notes, guided by expert perfumers. Even complete beginners will gain a profound appreciation for European luxury fragrance culture and its irreplaceable sense of ritual.

If you're looking to create your own custom perfume, you often need to book an appointment in advance. BY YAN breaks down this barrier by offering a "walk-in and play" open experience for Taipei Perfume Blending. This innovative concept perfectly aligns with modern, fast-paced lifestyles and their unpredictable schedules.

Whether you're aimlessly browsing at Miramar on a weekend afternoon, spontaneously planning a romantic date, seeking a quiet corner to unwind after work, or simply celebrating a special occasion, you can effortlessly walk into BY YAN anytime you pass by.

Here, you don't need any special preparation or prior planning. This "just go" freedom makes Taipei Perfume Blending an accessible part of everyday life, truly embodying the brand's original vision: that fragrance should be "an everyday exploration, not a high-barrier ritual."

“Why is perfume always taught as a ‘choice’ rather than being ‘understood’?” This is the core question posed by the founder of BY YAN. In today’s market, perfume is often reduced to just packaging and trendy labels, but BY YAN aims to change the relationship people have with it. To precisely capture the scent from the depths of each person’s soul, BY YAN cleverly integrates the emotional, century-old French craftsmanship with rational, modern AI technology.

This system isn't meant to replace a perfumer; rather, it translates a perfumer's implicit experience into an understandable logic. Your experience begins with an exclusive AI fragrance questionnaire. Based on your temperament, preferences, and emotional profile, the system quickly matches you with the scent profile that most closely reflects your current state from its vast database. It then combines an extensive library of ingredients with the Grasse three-tiered (Top/Heart/Base) fragrance structure to recommend the most suitable scent direction for you.

BY YAN extends its brand philosophy that "the scent itself is the star," ensuring that every experience yields a finished product comparable to a top-tier luxury boutique. Once your Taipei Perfume Blending experience is complete, there's no long wait or further processing required; you can take your custom perfume home immediately.

BY YAN has put a lot of thought into its packaging design, eschewing overly ornate decorations for minimalist, transparent glass bottles that perfectly showcase the perfume's pure essence. The outer layer features a silver metal tin, symbolizing rationality, protection, and a sense of technology. This substantial, premium feel in hand makes it ideal not only for gifting but also for personal use, offering a refined, ritualistic experience every time you open the box.

At BY YAN, you leave with more than just a simple shopping memory; you take home a work of aesthetic value that seamlessly integrates into your personal lifestyle and truly "stays with you."

When countless special occasions pop up throughout the year, we often struggle to find the perfect gift that truly conveys our appreciation and heartfelt intentions. The most precious gifts aren't always the most expensive; they're the ones that subtly say, "I understand you," and show the thoughtful effort of being "custom-made just for you."

And scent is the most honest medium for conveying that sentiment. While you can use words to package yourself and appearances to protect yourself, a person's reaction to a scent is very difficult to fake.

BY YAN's custom perfume experience is the ultimate memorable gift. Whether you're celebrating a best friend's birthday, planning a romantic Valentine's Day surprise, or simply treating yourself to some "me time," this experience inherently offers an irreplaceable blend of "story" and "exclusivity."

You can visit the venue yourself to translate someone's image and aura into a scent profile, then personally blend a unique perfume filled with emotional warmth. Or, bring them along to share the engaging and interactive process of creating a custom fragrance together.

While most perfume brands favor larger 50ml or even 100ml bottles, BY YAN takes a different approach, offering only exquisite 10ml designs. This strategy reflects the brand's commitment to "fragrance freshness."

Once a perfume is blended and exposed to air, its scent structure gradually oxidizes and changes over time. The 10ml design ensures that every drop of perfume is used at its most perfect, freshest, and prime state.

Additionally, these compact, elegant bottles fit easily into trendy small bags or pockets, allowing for graceful touch-ups anytime, anywhere. They also significantly reduce the psychological burden of buying a large bottle that might go unfinished.

Unlike typical perfume counters where you often feel rushed and pressured by salespeople, BY YAN is dedicated to creating a space where you can truly relax. That's why BY YAN places "absolutely no time limit on your experience." You can take your time at the counter, letting your thoughts settle without any pressure. There's no need to worry about olfactory fatigue; you can pause, take a deep breath, and reset your senses whenever you need to. With no time constraints, your sense of smell becomes your sole guide, allowing you to instinctively discover the scent that resonates most deeply with you, enjoying a moment of pure tranquility that is entirely your own.

BY YAN offers approximately 60 types of high-quality essential oil bases to ensure every custom perfume achieves the depth and sophistication of an international luxury brand. These ingredients draw on centuries of perfumery tradition from Grasse, France, ranging from light and bright citrus notes to elegant floral scents, and deep, grounding woody and oriental accords. This extensive library of fragrances allows you to layer delicate top, middle, and base notes, just like a professional perfumer.

Crucially, all ingredients at the venue meet strict IFRA international safety certification standards and come with comprehensive SDS (Safety Data Sheets) and COA (Certificates of Analysis). This means they are safe for pregnant women and children, and even pet-friendly.

A perfect perfume deserves packaging that matches its premium quality. Once your Taipei Perfume Blending is complete, BY YAN offers custom sealing services. You can give your unique creation a special name — whether it's an English name, an anniversary date, a secret code, or a short phrase reflecting your current mood. BY YAN will help print this onto a custom label for the minimalist glass bottle.

Finally, the finished product is carefully placed into a sleek silver metal tin and machine-sealed. If you're giving it as a gift, no further wrapping is needed; it already presents as a refined and elegant present.

Fragrance isn't just about self-expression; it's also a bridge to deeper connections, which is why BY YAN regularly offers special promotions for major holidays like Valentine's Day, Christmas, or anniversaries. These often include discounts for two people, allowing participants to sit side-by-side at the bar, explore scents together, and even challenge themselves to blend a custom perfume for each other.

Looking ahead, BY YAN plans to continue expanding its presence in prime department store locations while developing new services centered around "AI scent experiences." These will include corporate customization, educational fragrance workshops, and cross-industry collaborations.

Stepping into BY YAN's Miramar location, our mystery shopper, Lala, immediately felt as if she'd stumbled into a futuristic laboratory. Though the counter is situated on the bustling first floor of a department store, its minimalist, luminous, and cool metallic ambiance possesses a magical quality, instantly calming a restless mind.

The array of test tubes, beakers, and delicate glassware neatly arranged on the counter gleamed under the soft, refracted light. Just pulling up a high chair at the bar and observing these scientific displays sparked immense anticipation for the upcoming Taipei Perfume Blending experience.

What truly impressed our mystery shopper Lala and earned BY YAN top marks was how completely it shattered the high barrier to entry for Taipei Perfume Blending workshops, which typically require advance booking and fixed schedules. Instead, BY YAN boldly offers a "walk-in and play" experience!

This is a perfect design for someone like Lala, who prefers spontaneous plans and hates being tied down, or for anyone who's out shopping and suddenly wants to find a place to rest and try something new. No mental preparation needed—you can simply step in anytime, take a deep breath in the bustling city, and embark on a personalized journey of scent exploration.

Many first-time participants in Taipei Perfume Blending worry about feeling overwhelmed by a wall of scents, fearing they'll be complete novices. But at BY YAN, the experience begins with a unique AI system that guides you. Just answer a few simple questions about your intuition and feelings, and the AI quickly identifies your "personality keywords," then calculates a "destiny scent" profile that resonates with your soul. With this personalized scent profile as a perfect reference, Lala immediately felt at ease.

Next came the most therapeutic part: the scent-testing. BY YAN has no time limits on the experience, so I had plenty of time to leisurely sniff through about 60 premium French essential oils on the shelves. The perfumer guided me, helping me compare scents and patiently clarifying whether my preferences were driven by emotion, memory, or specific usage scenarios, then offered suggestions for fine-tuning. This completely respected, self-paced exploration made me feel incredibly relaxed.

It's worth noting that many scents I initially thought I wouldn't like were ultimately chosen, leading to a surprisingly delightful fragrance I never anticipated. As the founder said, "AI is a rational tool, but ultimately, it serves emotion." Since we're dealing with sensitive and ever-changing emotions, AI provides a "profile of possibilities" rather than a rigid final answer. This process also allowed me to understand myself more deeply, making this perfume truly "chosen, not assigned."

As the perfume blending experiment drew to a close, I was treated to BY YAN's signature "full of ritual" sealing process. After blending, I not only got to personally name my creation, but BY YAN also helped print a high-quality custom label, carefully affixing it to the minimalist, clear glass bottle, then boxing and shrink-wrapping my finished work.

Holding the weighty, substantial metal tin in my hands, I suddenly understood the brand's message: "Perfume isn't just a product; it's a cultural experience that can be understood, quantified, and felt."

What's more, Lala particularly appreciates BY YAN's commitment to the 10ml size. Lala owns several large-capacity perfumes, and there's always that subtle pressure of worrying they might spoil before she can finish them. But with five 10ml bottles, the oxidation problem is perfectly solved. Plus, they slip right into Lala's mini bag, allowing for elegant touch-ups anytime, anywhere.
