1. WEAR YOUR SUNSCREEN!
A spray tan will not protect you from buring in the natural sun. You always want to use a water resistent, lotion suncreen. The spray on sunscreens typically contain mineral oil and alcohol which is a receipe for stripping a spray tan. Although spray on sunscreen can be convenient, they don't provide the water resistance needed to protect your tan against chlorine or salt water.
Apply Lotion SPF (80 min water resistance) 20 minutes before entering the water. This will create a barrier between your tan and the elements.
If you are consistently in the water, re-apply every 30-40 minutes to keep a strong barrier. If you are just dipping in and out to cool off you can re-apply every 1.5-2 hours.
We highly suggest the salon version of Australian Gold in 15 or 30, it is super moisturizing and has great water resistance + protection. It is available in store for $9.99.
If you need a sunscreen that is spray tan safe + reef friendly we suggest using Sun Bum. Click Here for the Amazon link.
