You’ve earned your place: every detail reflects how far you’ve come

So why still rely on the same lotion or Vaseline “hack” to make your perfume last? Your fragrance, and your presence, deserves better.

The luxury pre-scent treatment your fragrance deserves

The Infinity+ perfume primer is a dedicated solution to make your perfume last longer. Born from years of research and development, the heart of our formula is the Scent-Care Complex which combines:

  • A unique system of surface hydrators, ceramides, and advanced silicones that grip scent molecules, slowing evaporation and extending your fragrance’s life.

  • A weightless, silky layer that melts into any skin type.

  • A truly scent-free formula designed to complement all perfumes.

The industry’s best-kept secret now in your routine

Australia’s #1 perfume primer — recommended by perfumers, adored by fragrance lovers, and expertly formulated to do one thing exceptionally well: make your scent last.

    • Preps skin for better fragrance application & improved longevity.

    • Calms and nourishes skin stressed by harsh perfume alcohols.

    • Locks in fragrance without changing its scent.

    • Invisible, weightless, fragrance-free formula for effortless application.

    • Works with all perfume types.

    • Friendly for all skin types.

    • Vegan & cruelty-free.

  • Lotion hydrates. Petroleum jelly seals. But neither are made for perfume. Your signature fragrance deserves more than a generic base — it deserves a formula crafted specifically to hold scent molecules in place and help them truly bloom on your skin.

    At the core of Infinity+ is our Scent-Care Complex: surface hydrators that restore moisture, ceramides that strengthen your skin barrier, and advanced silicones that anchor and extend fragrance wear. Together, they break the fade cycle — keeping your skin healthy and your scent lasting longer.

    • Ceramides (NP, AP, EOP): These essential lipids strengthen the skin’s natural barrier, preventing moisture loss and supporting fragrance retention by creating a protective layer.

    • Dimethicone: Acting as a skin protectant and emollient, this high-adherence silicone creates a smooth, silky layer over the skin that helps hold fragrance in place, reducing evaporation and increasing longevity.

    • Glycerin: This powerful humectant attracts moisture to the skin, ensuring hydration and creating an optimal surface for fragrance to last longer.

    • Tocopherol: A potent antioxidant that protects and nourishes the skin, enhancing its ability to hold fragrance while supporting overall skin health.

    • Shea Butter & Macadamia Oil: Rich in fatty acids and emollients, these ingredients help maintain a smooth, moisturised skin surface, allowing the perfume to adhere better and stay intact throughout the day.

Infinity+ Perfume Primer

★★★★★ (98 Reviews)

“I can literally smell my perfume for hours more. When you spend $280 on a perfume you want it to last.” - Caroline, M.

45 AUD | 30ml

Your scent tells a story — one only you can wear. It’s intentional. Elevated. Unmistakably you. Whether crisp, sensual, or quietly magnetic, even the most refined fragrances fade too soon on skin that’s unprepared.

The Infinity+ Perfume Primer is the intelligent fix. A nutrient-rich base that hydrates, soothes, and fortifies the skin barrier while extending the life, depth, and presence of your signature scent. By caring for the skin, it transforms the way fragrance wears, unlocking new layers of performance, longevity, and experience.

The results speak for themselves

  • ⭐️⭐️⭐️⭐️⭐️ “Finally, my perfume smells like it should all day.”

    I didn’t realise how much of my fragrance was being wasted until I used this. My perfumes used to disappear within two hours even the expensive ones. With By Zero I can still smell my scent on my wrist at night. It’s like unlocking the full potential of my perfume. I’ll never apply fragrance without it again.

    — Clara M., 26

  • ⭐️⭐️⭐️⭐️⭐️ “The difference is shocking.”

    I didn’t expect to notice such a huge change. My scent used to fade halfway through events, now I get complements hours later. It’s like my skin finally understands perfume even my cheaper perfumes last like niche ones now. Worth every cent!!!

    — Alina S., 34

  • ⭐️⭐️⭐️⭐️⭐️ “Low key a game changer.”

    I’ve tried every ‘hack’ Vaseline, lotion, layering… nothing worked. By Zero is different. It doesn’t just trap scent, it somehow makes the fragrance evolve more beautifully imo. My perfumes smell richer, smoother, and more complexl. I didn’t think a base could do that.

    — Renee L., 23

  • ⭐️⭐️⭐️⭐️⭐️ “For people who take scent seriously.”

    This isn’t just a product; it’s the missing step in every perfume lover’s ritual. It gives your fragrance the stage it deserves. I use high-end perfumes and always felt they never lasted like they should. Now, they do.

    — Sophie W., 29

  • ⭐️⭐️⭐️⭐️⭐️ “It makes perfume feel more intentional.”

    I love that this doesn’t smell like anything or feel greasy. It just melts in, and suddenly my perfume smells better: stronger, smoother, more me. It’s such a small step but makes a massive difference. I feel like I’m finally getting my money’s worth from my fragrances.

    — Houda R., 32

  • ⭐️⭐️⭐️⭐️⭐️ “Didn’t expect it to actually work, but it does.”

    I’m super skeptical about these kinds of things, but wow. My perfume usually disappears halfway through the day, especially in summer. With this, it just lasts. I still catch whiffs hours later. My boyfriend even noticed.

    — Katrina S., 27

The genesis of a scent. A return to zero, where everything is pure possibility.

We see fragrance as a language beyond words — an invisible voice, an echo of the self, a presence. By Zero is designed for women who are constantly transforming, but always themselves.
