Frequently Asked Questions

How long does a 100ml (3.4 oz) bottle of perfume last?

A 100ml bottle contains roughly 1,000–1,400 sprays depending on the pump. If you apply 4 sprays per day every day, that's approximately 250–350 days of use. Use it less frequently — say 3 days a week — and the same bottle can easily last 1.5 to 2 years.

Which fragrance concentration lasts the longest on skin?

Parfum (Extrait de Parfum) lasts the longest — typically 8–12+ hours — because it contains the highest concentration of fragrance oils (20–40%). Eau de Parfum follows at 6–8 hours, Eau de Toilette at 4–6 hours, and Eau de Cologne at 2–4 hours. Higher concentration also means you need fewer sprays per application, so the bottle lasts longer too.

Does perfume expire or go bad?

Yes, perfume can expire. Most fragrances last 3–5 years from their manufacture date, though some can remain good for up to 10 years if stored properly. Signs of expiry include a change in color (yellowing), a vinegary or sour smell, or reduced projection. Proper storage away from heat and light significantly extends shelf life.

How long does cologne/perfume scent last on skin?

On average, Eau de Cologne lasts 2–4 hours, Eau de Toilette 4–6 hours, and Eau de Parfum 6–8 hours. Parfum can linger 8–12 hours or more. Skin type also matters — oily skin tends to hold fragrance longer than dry skin. Applying to pulse points and moisturized skin can extend wear time.

Why doesn't my perfume last long on me?

Dry skin absorbs fragrance quickly, causing it to fade faster. Other factors include applying to dry or unmoisteurized skin, rubbing wrists together after spraying (which breaks down molecules), applying in hot environments, and choosing a lower concentration like Eau de Cologne. Layering with a matching body lotion or applying to hair or clothing can improve longevity.

How should I store perfume to maximize its lifespan?

Store perfume in a cool, dark, and dry place away from direct sunlight, humidity, and temperature fluctuations. A bedroom drawer or closet shelf is ideal. Avoid bathrooms, windowsills, and areas near radiators. Keep the bottle tightly capped and in its original box to block light exposure.

How many sprays does a perfume bottle typically hold?

A standard perfume pump dispenses approximately 0.1 ml per spray. So a 50ml bottle holds roughly 500 sprays, a 100ml bottle around 1,000 sprays, and a 200ml bottle about 2,000 sprays. The exact count can vary slightly by brand and nozzle design, but 0.1–0.15 ml per spray is a reliable industry estimate.

Is 10-year-old cologne still good to use?

It depends on how it was stored. A fragrance kept sealed in a cool, dark environment may still smell acceptable after 10 years, though the top notes often degrade first. If the scent smells noticeably different, sharper, or has changed color significantly, it has likely oxidized and turned. It won't harm your skin but may not smell as intended.
