Within what time frame should hydration and barrier lipids be reapplied after toweling off?
Answer
Hydration and barrier lipids must be applied aggressively within five minutes of toweling dry.
Following the immediate rinse, there is a critical window of opportunity to mitigate the drying effects of saltwater exposure, which must be utilized quickly. Once the skin has been gently patted dry (emphasizing patting over rubbing), the goal shifts to aggressively reintroducing hydration and lipids to reverse the moisture loss caused by salinity. This restorative process must begin swiftly—ideally within five minutes of toweling off—to effectively trap the water recently applied back onto the skin surface and support the skin barrier's recovery process before excessive trans-epidermal water loss continues.
