Quick Verdict
YSL Y Eau de Parfum takes the top spot in this head‑to‑head test. Its bright opening, balanced dry‑down, and moderate longevity make it a versatile work‑day companion. Byredo Mojave Ghost, however, excels when you need a softer, more ethereal scent for evening or cooler months. Both are worth keeping, but YSL Y earns the overall win for its broader daytime appeal.

Scent Profile Compared
YSL Y EDP, The fragrance opens with a burst of bergamot, ginger, and crisp green apple. That fruity‑spicy triad quickly gives way to a heart of lavender, sage, and geranium, lending a modern fougère feel. The base settles into warm cedar, amber, and a whisper of musk, creating a clean yet slightly woody finish. The journey from top to base feels purposeful; the apple brightens the opening, while the herbal heart adds sophistication without overwhelming the senses.
Byredo Mojave Ghost, Mojave Ghost begins with a subtle push of ambrette (musk seed) and a hint of pink pepper that adds a faint sparkle. The heart is dominated by jasmine, lily‑of‑the‑valley, and a soft sandalwood note, giving the perfume a ghost‑like floral veil. The dry‑down is anchored by musk, cedar, and a touch of amber, which together create a powdery, almost translucent aura. Unlike YSL Y’s upfront brightness, Mojave Ghost eases in gently, making the scent feel more like a whispered memory than a statement.
Both fragrances share a clean, aromatic backbone, but YSL Y leans toward a crisp, energetic profile, while Mojave Ghost leans into a muted, floral‑woody elegance.
Longevity and Sillage
YSL Y EDP, Expect about five to seven hours of noticeable scent on skin for most wearers. The projection is moderate; you’ll get compliments in an office setting without overwhelming a crowded room. The initial spice from ginger helps the fragrance linger, but the woody base does not cling heavily, which is why the scent fades to a subtle, clean musk as the day progresses.
Byredo Mojave Ghost, Longevity is a touch shorter for many, hovering around four to six hours, though the scent can linger longer on fabrics. The sillage is delicate, more of a soft halo than a bold cloud. This makes it ideal for close‑range encounters; you’ll notice it when someone is within arm’s length, but it won’t dominate a large space. The musk and cedar in the base do provide a gentle anchor that persists without being aggressive.
Best Occasions and Seasons
YSL Y EDP, Because of its bright opening and clear woody finish, YSL Y shines in daytime settings, think office meetings, brunches, or weekend errands. Its crisp apple and bergamot work well in spring and early summer when you want something fresh but not overtly floral. The fragrance also holds up in cooler months, offering a touch of warmth without feeling heavy.
Byredo Mojave Ghost, This perfume thrives in cooler weather, autumn evenings, winter gatherings, or late‑summer night events when the air is a bit chillier. The ethereal jasmine and lily‑of‑the‑valley become more noticeable when the temperature drops, allowing the scent’s subtlety to unfold. It’s an excellent choice for formal dinners, intimate dates, or art openings where a low‑key, elegant presence is preferred.
Price and Value
Neither fragrance is cheap, but each offers distinct value. YSL Y provides a versatile, longer‑lasting experience that can justify a higher spend for daily wear. Mojave Ghost, with its niche positioning and refined composition, feels like an investment in a signature scent for special moments. As always, check current price on Amazon before you decide, since promotions and stock levels can shift dramatically throughout the year.
Which Should You Buy?
If you need a scent that can transition from a busy morning commute to a casual lunch with friends, YSL Y EDP is the clear pick. Its bright opening, moderate longevity, and universally appealing fougère heart make it a safe bet for any active lifestyle. On the other hand, if your wardrobe leans toward understated elegance and you enjoy a perfume that whispers rather than shouts, Byredo Mojave Ghost is the better companion. Its delicate floral‑woody blend suits evenings, cooler climates, and moments when you want to leave a subtle, lingering impression.
In short, choose YSL Y for energetic daytime use and Mojave Ghost for low‑key evening elegance. Both will enrich your fragrance collection, but your personal routine and preferred scent intensity should drive the final decision.
