Have you ever noticed how a lot where tanners wash off in the shower and others leave colour for days? The key to that answer is how the product gets its colour. Instant tans and gradual tanning products look exactly the same when applied but the chemistry is very different.

If you get to grips with the difference, you’ll be able to pick the right formula for your routine and score yourself the finish you want.

How Does Instant Tan Work?

Instant tan is a product designed to give your skin instant colour. Most formulas contain cosmetic bronzers that simply sit on the skin. These aren’t pigments that darken with time, they are pigments that provide a darker appearance immediately upon application.

The colour merely rests on the skin − which is why it can be washed away with soap and water.

This is why the best instant tan will provide you with a temporary bronzed finish that works wonders for an event, night on the town, or other special occasion but probably won’t survive after your next shower.

Why Does Instant Colour Always Wash Off?

Most instant soaking up products are created for short-term colour. The immediate effect of the bronzer does not involve a chemical reaction with the individual.

Water and cleansing products used in the shower to undo the surface pigment. Even further scrubbing by a towel can take the colour away more effectively.

You will see this tan wearing off quicker from areas that experience more friction, such as:

• Hands and wrists
• Knees
• Elbows
• Feet
• Areas covered by tight clothing

At first glance, the colour can seem rather dramatic but there may not always be a long-lasting tan behind such intense pigmentation.

How will Gradual Tan Give Lasting Colour?

A gradual tanning product works in a different way. Usually it contains DHA, or dihydroxyacetone. It reacts with the amino acids in the top layer of the skin.

The reaction produces brown molecules that slowly darken your skin.

Due to the fact that this colour develops up within the outer level of skin, as opposed to dreaming about on top, it does not have a tendency to wash out entirely in one shower.

And this is also the reason why a best gradual tanning lotion would stay on for more than one day.

So, Why Doesn’t Gradual Tan Just Wash Off?

Showering may wash away some superficial residue, but it does not instantaneously undo the chemical reaction that DHA has caused.

The pigment wears off as the cells in outer skin slough away naturally. Washing and rubbing can hasten this process but the pigment persists until those cells are replaced.

It also explains why natural-looking tans come and go gradually, rather than disappearing all at once.

Instant Tan vs Gradual Tan

The main difference is the type of colour each product provides.

Instant tan:

• Gives immediate visible colour
• Mainly uses surface bronzers
• Can wash off in the shower
• Works well for short-term results

Gradual tan:

• Builds colour over repeated applications
• Uses tanning agent like DHA
• Develops over time
• This gradually disappears when the most superficial skin cells naturally shed

First or second method is your choice, depending on the speed you want and whether you enjoy pounding pavements.

Can You Use Both?

Yes. Some utilise an instant bronzer whenever they are searching to achieve immediate colour and a gradual soaking up product to offer them a golden glow for an extended duration.

The best gradual tanning lotion allows you to build up results over days for a softer look if that is your preference. It also gives you greater control over the colour depth.

Choosing the Right Tanning Product

As the name suggests, best instant tan provides colour when you need it most and want to avoid longer-lasting commitment. It’s also handy when you need your tan to wash off after an event.

Gradual formula is better when you want colour that builds slowly and lasts after the shower.
