You can use any commercially available shaving foam or gel to wet shave with your Philips Wet & Dry electric shaver.
While wet shaving is more energy-intensive and may drain the battery of your shaver more quickly, it does not impact the shaver's performance.
Note: before getting your shaver wet, always check that it's waterproof. Refer to the user manual (also available online) or check the back of your shaver for a tap or bathtub icon.
