If you've ever stood in a fragrance aisle wondering why one bottle says eau de cologne and another says eau de parfum, you're not alone. The names sound like marketing, but they point to something real: how much fragrance oil is dissolved in the alcohol. That ratio changes how a scent behaves on your skin, how far it travels, and how long it stays. Here's what the terms mean, in plain language.
The Concentration Ladder
Fragrance is essentially aromatic oil mixed with alcohol and a little water. The percentage of oil in that mix is what the French terms describe.
Eau de Cologne (EDC) sits around 2 to 5 percent oil. It's light, it fades fast, and it's meant to be splashed on generously. Think of it as a quick refresh rather than a statement.
Eau de Toilette (EDT) runs roughly 8 to 12 percent. This is the concentration you'll find in most mass-market releases. It works, but on dry or warm skin it can thin out within a few hours.
Eau de Parfum (EDP) lands between 15 and 30 percent. More oil means the scent has more material to work with. It tends to open slower, settle deeper, and stay present longer. At 20.O2, our formulas sit at 25 to 30 percent concentration, built with French and Swiss oils, made in the UAE.
Parfum or Extrait goes above 30 percent. Intense, long-wearing, usually applied sparingly with a stopper rather than sprayed.
One honest note: concentration alone doesn't guarantee longevity. Your skin chemistry, the weather, and how much you apply all play a role. A rich EDP on dry skin in a cold room will behave differently from the same formula on oily skin in Dubai in August. There's no spray count that predicts how long a scent lasts for you specifically.
What Sillage Means
Sillage (say it: see-yazh) is the French word for the trail a boat leaves in water. In fragrance, it describes the scented wake you leave behind when you walk out of a room. High sillage means people notice you've been there. Low sillage means the scent stays close to your skin, almost private.
Projection is related but slightly different. It's how far the scent radiates from your body while you're still in the room. A fragrance can have strong projection in the first hour and then settle into a softer, skin-close sillage for the rest of the day. That shift is normal, and often desirable.
Neither high nor low sillage is objectively better. A loud scent in a small meeting room is a different experience from the same scent on a beach. Knowing your context helps you choose.
Four Scents Worth Knowing, and When to Wear Them
Vanilla Smoke Vanilla Smoke
Our Creation of Tobacco Vanille. Notes: Tobacco, Spices, Vanilla, Cacao, Dried Fruits, Woods.
This one opens with a dry, almost papery tobacco and then the vanilla and cacao come in behind it, warm and unhurried. It's the kind of scent you notice the next morning on a wool scarf you wore the night before. Wear it when the temperature drops, or when you want something that reads as considered rather than loud. AED 99 for 50ml, AED 149 for 100ml.
Crimson Aura Crimson Aura
Our Creation of Baccarat Rouge 540. Notes: Saffron, Amberwood, Fir Resin.
Saffron gives it a metallic, almost mineral edge at the start. Then the amberwood takes over and the whole thing becomes this warm, slightly sweet haze that sits close to the skin. The sillage is moderate but persistent. People will ask what you're wearing, usually a few hours in. AED 99 for 50ml, AED 149 for 100ml.
Noir Sauvage Noir Sauvage
Our Creation of Sauvage. Notes: Calabrian Bergamot, Pepper, Lavender, Geranium, Cedarwood, Labdanum.
The bergamot hits first, clean and citrusy, and then the pepper and cedarwood pull it in a drier direction. Lavender keeps it from going too dark. This is a high-projection scent, the kind you feel on the back of your hand an hour after applying. Works across a wide range of situations, from a morning commute to an evening out. AED 99 for 50ml, AED 149 for 100ml.
Her Dominion Her Dominion
Our Creation of Libre. Notes: Mandarin, Orange Blossom, Vanilla.
Soft and genuinely warm without tipping into cloying. Mandarin lifts the opening, orange blossom keeps it floral and fresh, and the vanilla underneath rounds it into something comforting rather than sugary. Low-to-medium sillage, which makes it a good choice for close contact: a date, a quiet dinner, anywhere you want the scent to be discovered rather than announced. AED 99 for 50ml, AED 149 for 100ml.
How We Build Them
Every 20.O2 formula is an original composition made in the UAE using French and Swiss aromatic oils. The 25 to 30 percent EDP concentration isn't a claim we make for marketing; it's the starting point for how we formulate. We also offer a 10ml alcohol-free oil roll-on for each scent, which behaves differently again: oil carries fragrance closer to the skin, with less projection but often more staying power on dry skin types.
Sadiq and Saara built 20.O2 around a simple idea: icon-grade scent shouldn't require a luxury markup to access. The price reflects that.
Try Before You Commit
If you're still figuring out which concentration and sillage level suits you, the AED 59 Starter Kit Starter Kit is the practical way in. It lets you test the actual formula on your skin, in your climate, before you buy a full bottle. That's the only way to know how a scent will really behave for you.
FAQ
What is the difference between eau de cologne and eau de parfum? Eau de cologne contains roughly 2 to 5 percent fragrance oil, so it's light and fades relatively quickly. Eau de parfum sits between 15 and 30 percent oil, which means more depth, slower development, and a longer presence on skin. The higher the oil concentration, the more the scent has to work with over time.
What does sillage mean in perfume? Sillage is the scented trail a fragrance leaves behind you, the olfactory equivalent of a wake in water. A high-sillage scent fills a room and lingers after you've left. A low-sillage scent stays close to your skin and is more personal. Neither is superior; it depends on where and how you want to wear it.
Does a higher concentration always mean longer-lasting? Generally yes, but it's not a guarantee. Skin type, humidity, body heat, and how much you apply all affect longevity. An EDP on dry skin in a cool environment may not outlast an EDT on warm, well-moisturised skin. The only reliable test is wearing it yourself.
How do I know which strength suits me before buying a full bottle? The 20.O2 Starter Kit Starter Kit is AED 59 and lets you test the actual EDP formula on your skin before committing to a 50ml or 100ml bottle. It's the most straightforward way to understand how a scent performs for your specific skin chemistry and climate.
