During a recent warm weather holiday where my children were spending a lot of time at the outdoor pool, I needed to deliver a good explanation as to why their water resistant sunscreen had to be applied several times through the day. Although nobody at my house argues with me about applying sunscreen – this is one fight that you just can’t win – there was some squawking about the frequency of application. Since some parts of North America are starting to heat up, this might be a good time to cover the finer points of what defines a water resistant sunscreen.
Water Resistant Sunscreen Vs Waterproof Sunscreen
Many sunscreen manufacturers advertise their sunscreens as being waterproof. However, since 2002, the FDA has required companies to eliminate the use of the word ‘waterproof’ when referring to sunscreens. Not is it misleading, but it is also potentially dangerous. Despite this, you will still find sunscreens labeled as being waterproof, leaving skin exposed to unprotected UV exposure.
New regulations allow the use of the terms water resistant and very water resistant sunscreens. Water resistant formulations provide 40 minutes of protection upon exposure to water, while very water resistant products deliver up to 80 minutes.
Sunscreen For Water Activities
If you (and you family) will be spending time outdoors follow these guidelines to keep skin protected. And you can tell them that your bossy pharmacist said you had to!:
- Apply sunscreen 20 – 30 minutes prior to UV exposure.
- Reapply frequently. Every 40 minutes for water resistant formulations and 80 minutes for very water resistant formulations. Reapply more frequently if sunscreen is washed, rubbed or sweated off.
- Sunscreens should not be used to increase the amount of time you spend outside.
- Always use sunscreen in combination with other sun protection measures including: shade, clothing, hats and sunglasses.
Look for water resistant sunscreens that deliver UVA and UVB protection amongst Anthelios sunscreens, Ombrelle sunscreens and Cotz SPF 58.
