Why does my skin burn if I swim after shaving?

Your skin is at its most sensitive directly after shaving, so give it a 30-minute rest before you hit the beach or go swimming. The chlorine or salt in the water will aggravate freshly shaved skin, as will suntan lotions and sunscreens that contain alcohol.

After shaving, you should also allow for 30 minutes to pass before you apply lotions, moisturizers or medications. If you have to moisturize straight away, use a cream rather than a lotion and don’t use any exfoliating moisturizers that contain alpha hydroxy acids.
