Aftershave is a product made to be used straight after shaving: a splash, lotion or balm that cools, refreshes or soothes the skin, usually with a light fragrance. Cologne is made to be worn as fragrance — and in everyday American use the word simply means a fragrance marketed to men, of any strength. So the difference is mainly one of purpose. An aftershave’s scent is a pleasant side effect and usually fades within an hour or so; a cologne’s scent is the point, and is usually stronger and longer-lasting. Neither word is defined by law, so the label tells you less than the description and your own nose.

What aftershave is for

Shaving scrapes away a thin layer of skin along with the hair, and can leave it tight, warm or irritated. Aftershaves were developed to deal with that moment. They come in three broad kinds:

  • Splashes — thin, often alcohol-based liquids that feel cold and bracing. The alcohol evaporates quickly, which is part of the "sting" many people remember.
  • Lotions — lighter emulsions, often with less alcohol, somewhere between a splash and a moisturiser.
  • Balms — creamy, usually alcohol-free or low in alcohol, and aimed at soothing and moisturising rather than refreshing.

Many aftershaves are lightly scented, often with a version of the same fragrance as a cologne or eau de toilette in the same range. The fragrance is typically lower in strength than the spray, so it gives a brief, close impression rather than a lasting trail.

What cologne is

The word has two meanings, and it helps to know which one is meant:

  • The strength. Eau de Cologne is one of the lighter fragrance strengths, below eau de toilette. The name comes from the German city of Cologne, where a famous citrus-and-herb water was sold in the eighteenth century; see The History of Eau de Cologne.
  • The everyday word. In the United States especially, "cologne" is used for any fragrance aimed at men, whether it is technically an eau de Cologne, an eau de toilette or an eau de parfum. We untangle this in Perfume vs Cologne.

In either sense, a cologne is made for wearing on skin or clothes as a fragrance, with no particular job to do for the skin.

An aftershave looks after the skin and smells pleasant while it does. A cologne is there to be smelled.

The differences at a glance

  • Purpose: aftershave treats freshly shaved skin; cologne is worn for its scent.
  • When: aftershave right after shaving; cologne whenever you choose to wear fragrance.
  • Where: aftershave on the shaved area; cologne on the neck, chest, wrists or clothes. See How to Apply Perfume.
  • Strength: aftershave’s fragrance is usually lighter; colognes range from light to quite strong, depending on the concentration. See Perfume Concentrations Explained.
  • How long it lasts: an aftershave scent is usually brief; a cologne lasts longer, though how long depends on its strength and composition. See Sillage, Projection and Longevity.

Can you use one instead of the other?

Aftershave as fragrance: you can, but expect a quieter, shorter-lived scent. Applying a splash to the neck or chest rather than the face works for a light, fresh impression that fades by mid-morning.

Cologne as aftershave: generally not a good idea. Alcohol-based sprays on freshly shaved skin often sting, and they contain nothing to soothe. If you like both, use an unscented or matching balm after shaving and apply the fragrance to unshaved skin or clothing.

Using them together

Many fragrance ranges sell an aftershave balm or lotion alongside the spray. Using the two together is a simple form of layering: the balm gives a soft first layer of the same scent, and the spray adds strength and length. If you prefer a different fragrance, an unscented balm avoids two perfumes competing on your skin. See How to Layer Perfume.

Common questions

Does aftershave last as long as cologne?

Usually not. Aftershaves are made to be refreshing and gentle on shaved skin, so their fragrance is typically lighter and fades sooner.

Is aftershave only for men?

No. It is marketed to people who shave their faces, but anyone can use a balm after shaving, and anyone can wear a cologne. See What Makes a Fragrance Unisex?.

Why does aftershave sting?

Most splashes contain alcohol, which feels sharp on skin that has just been shaved. Balms and lotions with little or no alcohol are gentler.

Do I need aftershave if I wear cologne?

Not for the fragrance. Whether you want an aftershave depends on how your skin feels after shaving; an unscented balm lets you keep your cologne as the only scent.
