How Long Does Your Tan Really Last? Understanding Product Shelf Life and Expiry

We all love that post-tan glow, but what happens when your favourite tanning mousse or lotion has been sitting on the shelf for a while? Does it still work the same? Is it safe to use?

Let’s talk about how long your tanning products actually last, what happens when they expire, and how to make sure your tan stays fresh, flawless, and skin-safe.

How Long Do Self-Tanning Products Last?

Most tanning products, such as mousses, lotions, and sprays, have a shelf life of around 12 to 24 months when unopened. Once opened, they generally last about 6 to 12 months, depending on how they are stored.

Custom Tan products are made with high-quality, vegan-friendly ingredients designed to stay stable and effective. However, exposure to heat, light, and air over time can cause the key tanning ingredient, DHA, to lose its strength. When that happens, your tan might not develop as evenly or as rich in colour.

How to Tell If Your Tan Has Expired

It is easy to spot when your self-tanner is no longer as fresh as it used to be. Look out for:

• Colour change: If your mousse or lotion looks darker, or different from when you first opened it, it may have oxidised.
  
• Strange scent: A sour or off smell means the formula is no longer at its best.
  
• Texture shift: If the product looks separated, runny, or clumpy, it is time for a new one.
  
• Weaker results: Expired tan often develops unevenly or fades faster.

If you notice any of these signs, it is best to replace the product with a fresh bottle so you get that smooth, streak-free glow Custom Tan is known for.

What Happens When You Use an Expired Tan

Using an old tan is not usually harmful, but it can affect your final result. The colour might not develop properly, and you could end up with a patchy or uneven tone instead of that signature Custom Tan finish.

In some cases, older formulas can also cause mild irritation, especially if preservatives or natural ingredients have broken down. A fresh product always gives better results and is gentler on your skin.

How to Keep Your Tan Fresh for Longer

• Store your tanning products in a cool, dry place away from direct sunlight.
  
• Keep the cap tightly closed after each use.
  
• Avoid storing your tan in hot or humid spaces such as your bathroom or car.
  
• Always use clean hands or a mitt when applying, and avoid letting water get into the bottle.
  

A little care goes a long way in keeping your tan fresh, effective, and ready to deliver that signature Custom Tan confidence.
