Response to your inquiry in detail
Yes, it is necessary to reapply sunscreen every 2 hours to maintain its effectiveness and protect the skin from harmful UV rays. According to the American Academy of Dermatology, this is because the active ingredients in sunscreen can break down over time, especially with exposure to water or sweat. It is also important to reapply sunscreen after toweling off or drying the skin.
In addition, using a higher SPF (sun protection factor) sunscreen does not mean you can apply it less frequently. The SPF only indicates the level of protection against UVB rays, which cause sunburn, but does not indicate protection against UVA, which contribute to skin aging and cancer.
Sunscreen should be applied generously, with at least one ounce (about a shot glass full) for the entire body and a nickel-sized amount for the face and neck. It should also be applied 15-30 minutes before sun exposure to allow absorption into the skin.
Not convinced that reapplying sunscreen is necessary? Consider the following quote from the Skin Cancer Foundation: “Sunscreens are not meant to last all day, they wear off and become less effective with time. Sunscreens should be considered as a necessary form of protection from the sun, but not the only form.”
Here’s a table summarizing some important facts about sunscreen and sun protection:
| Fact | Explanation |
|---|---|
| Sunscreen should be applied every 2 hours | Sunscreen can break down over time and with exposure to water or sweat |
| Higher SPF does not mean less frequent application | SPF only indicates protection level against UVB, not UVA |
| Sunscreen should be applied generously | At least one ounce for the entire body and a nickel-sized amount for the face and neck |
| Sunscreen should be applied 15-30 minutes before sun exposure | To allow for absorption into the skin |

Remember, protecting your skin from the sun is important for both immediate and long-term health. Don’t forget to reapply your sunscreen every 2 hours and seek out shade whenever possible.

Do I really need to reapply my sunscreen?
You really do not have to reapply sunscreen every two hours. Sunscreens are broken down by the effects of direct exposure to daylight, not by the passage of time.
