Thanks for reaching out to Bondi Sands💖
Yes, The Liquid Gold Self Tanning Foam is not required to be washed off as it does not have a colour guiide which can transfer onto your clothing.
However while the product is transfer resistant it is not transfer proof, So heavy sweating can cause a bit of colour transfer especially if you are wearing white.
Rest assured all ingredients in our products are water soluble and should easily wash out. There are no staining agents in the products, but obviously the active ingredients are developed for a certain output when applied to skin. We are not aware of all reactions of these ingredients when applied to various fabric types.
We hope this helps and please reach out if you have any further questions xx
Sorry that we missed your question,
Yes you can definitely leave the Liquid Gold Self Tanning Foam on overnight.
This will only affect how deep your results will be.
Hope this info helps, Have a wonderful day!
