Never Combine Fake Tanning with SPF
Combining your fake tan and SPF may sound like a fantastic idea, but be aware that the SPF will break down because of the fake tan’s chemical, DHA.
It’s very likely that all of the sunscreen protection will have been entirely destroyed by the time the product has left the warehouse and arrived in your suitcase.
The formula of SPF can also break down when applied over freshly tanned skin, which is another reason why you should ensure you’ve tanned at least 24 hours before going outside.
