Colognes: Do They Lose Their Scent Over Time?

Colognes and perfumes can lose their scent over time, but this is not due to the passage of time itself. Instead, exposure to heat, humidity, and light will break down a cologne's chemical composition through oxidation, altering its scent or even destroying it entirely. The same is true of perfumes, which can turn sour or develop notes of plastic or vinegar. To prevent this, colognes and perfumes should be stored in their original bottles, in a cool, dry, dark place, such as a drawer or cupboard, and used within three to five years of opening.

Heat and light can break down cologne

To preserve the integrity of your cologne's scent, it is recommended to keep it below 15 degrees Celsius or 59 degrees Fahrenheit. Additionally, it is advised to avoid storing cologne in the bathroom, as the heat and humidity can negatively impact the fragrance. Instead, a dresser drawer is the best place to keep it.

Light can also break down the molecules of a fragrance, making its composition unstable and prone to oxidation. This will alter the scent and may cause it to become less effective over time. Therefore, it is important to keep cologne away from direct sunlight and bright light sources to ensure that it lasts as long as possible.

By taking these precautions and properly storing your cologne, you can ensure that it maintains its scent and lasts for an extended period.

Storing cologne in a cool, dry place

Ideally, cologne should be stored below 15 degrees Celsius or 59 degrees Fahrenheit. A walk-in closet or a dresser drawer is a good option, as long as it's not too hot or humid. Keeping cologne in its original box can also help protect it from light and heat.

It's worth noting that direct light will break down the molecules of a fragrance, making its composition unstable and prone to oxidation. This process can change the scent or even destroy it. Heat will also break down fragrance molecules and alter their chemical makeup, so it's best to keep cologne away from sources of heat.

In addition to a cool, dry place, the original box or a drawer, a fridge or freezer can be a good option for storing cologne. Wrapping the bottle in aluminium foil and placing it in the freezer will help maintain a cool temperature without exposing the fragrance to light. However, if the fridge or freezer is constantly being opened, this may not be the best option as the light and temperature changes can impact the cologne.

By storing cologne in a cool, dry place, you can help prevent oxidation and degradation of the fragrance, ensuring it lasts longer and smells as intended.

How long cologne lasts

How long your cologne lasts depends on a few factors, such as ingredients, time since opening, and storage conditions. Most fragrance manufacturers recommend that you toss your bottle after one to three years, but it's sometimes okay to keep using a bottle for four or even five years.

The oxidation of a fragrance can cause it to go sour or develop an acidic or metallic smell. This is caused by too much oxygen inside the bottle, which alters the molecules of the fragrance. Different formulas are more prone to oxidization, which is why some perfumes last longer than others. For example, woodsy notes, amber, and leather are quite stable, even after three years. On the other hand, citrus and floral notes will degrade the quickest when improperly stored.

To make your cologne last longer, keep it away from light and heat. Light will break down the molecules of a fragrance, making its composition unstable and prone to oxidation. Heat will also break down fragrance molecules and alter their chemical makeup. As a result, it is recommended to store your cologne in a cool, dry place, like your nightstand drawer, instead of your medicine cabinet or bathroom.

Additionally, it is best to keep using the cologne until the bottle is empty. This is because when the bottle is half empty, the oxygen inside increases the risk of alteration. If you have multiple perfumes, rotate your collection so that the lowest bottles get used first, and the rest should be stored in a cupboard or drawer.

It is also recommended to store your cologne in its original bottle. While it may be more convenient to decant it into atomizers or smaller tubes, this exposes the fragrance to oxygen, which can cause it to spoil faster.

Applying cologne to dry skin

When applying cologne, it is best to do so immediately after showering, as the shower cleanses the body of any other scents and opens the pores, aiding the scent absorption. It is also important to ensure that the skin is completely dry before applying cologne, as applying cologne to dry skin helps the scent to lock on. The pulse points, such as the neck, wrists, inner elbows, chest, and forearms, are the best spots to apply cologne, as these areas are heated and help diffuse the scent throughout the day.

When spraying cologne, hold the bottle 3-6 inches away from the body to avoid over-application or under-application. It is also recommended to start with a light application and choose one area, like the neck or forearms, for spraying. If the scent fades quickly, choose another area to spray next time. Additionally, avoid rubbing the cologne into the skin, as this can cause the scent to fade faster.

Applying an unscented body lotion or moisturizer before applying cologne can also help to ensure the skin is hydrated and ready for the scent. It is also important to note that applying cologne to the skin rather than clothing is generally recommended, as fragrances are designed to interact with the oils and pH of the skin.

Skin chemistry and how it affects cologne

Skin chemistry is a major factor in explaining why cologne smells different from person to person. The skin is a complex organ made up of water, fat, salts, sugars, proteins, fibres, and hairs. The distinct composition of each person's skin means that colognes will perform differently from person to person.

The body's natural pheromones also play a role in determining how cologne reacts with body chemistry. Pheromones are secreted in the body's erogenous areas, and they contribute to each person's unique natural scent. Applying cologne can be thought of as layering a scent over the body's natural scent, and these scents may prove to be highly compatible or may clash.

In addition to pheromones, all bodily fluids can affect skin chemistry. Sweat, for example, can mingle with cologne, creating a unique scent that is personal to an individual's body chemistry. Citrus and green notes tend to become amplified when combined with sweat as they gain greater depth.

Diet and lifestyle can also affect skin chemistry, as they have the power to alter the core chemical makeup of the body. This, in turn, will determine how a particular scent performs. For example, eating certain foods such as garlic can cause sulfur-containing compounds to be present on the skin, which may not mix well with a particular cologne. Similarly, consuming alcohol can cause alcohol to be secreted through the skin, which can also affect how cologne smells.

The texture or type of skin does not change how a cologne smells but can impact the performance or longevity of a scent. Colognes cling better to well-moisturized or oily skin. On the other hand, it is difficult for fragrance molecules to adhere to dry skin due to the lack of oil or moisture, causing them to evaporate quickly.
