Why did my spray tan turned green? It's not cool

Top 3 reasons that your tanning product might turn green

  1. It’s gone out of date
  2. It’s been stored incorrectly
  3. Incorrect preparation and maintenance

Why did my spray tan turned green?…It’s out of date

This is your biggest clue to the question of “why did my spray tan turn green”. Self tanning products use DHA (Dihydroxyacetone), sourced from natural plant sources like sugar cane, so like all naturally-derived ingredients have a shorter shelf life (typically 6 months).

Why did my spray tan turned green?…Incorrect storage

Oxidisation can occur within self tanning products when they aren’t stored correctly, resulting in excess oxygen breaking down the DHA. Try to keep your tan happy by storing it in a cool, dark place out of direct sunlight.

Why did my spray tan turned green?…Bad preparation & maintenance

Green armpits will never be a good look, and while it’s not lasting, it is often caused by other beauty products reacting with your tan rather than the tan itself. Try to avoid using perfumes, deodorant and moisturisers before and immediately after tanning. Always ensure your skin is cleansed and exfoliated before any tanning application to remove impurities and create a longer-wearing colour.


If possible, you should always seek out professional practitioners with a good reputation to apply your tan. Word of mouth is probably the best recommendation so seek out others who have had a good experience. Look up reviews online and on social media – don’t take a chance with your spray tan!
