The simple answer is NO–at least when it comes to water-resistance.
In a recent study conducted by Consumer Reports, 43% of the 65 water-resistant sunscreens that were tested FAILED to meet their SPF claim on their labels after the area was submerged in water as indicated on the label for water resistance. Some of them, missed their mark dramatically.
RECOMMENDATION: As always, it is recommended that one re-apply sunscreen after toweling off, sweating, or swimming.
