Sunblock and sunscreen are both products that provide protection from the suns harmful UV rays. However, there are some differences between the two products, including their ingredients, effectiveness, and application. Here are some details about sunblock and sunscreen based on the search results:
Sunblock:
- Contains zinc oxide and titanium dioxide, which are the ingredients that meet the FDAs requirements to be labeled as safe and effective.
- Reflects the suns rays away and doesnt penetrate the skin. This is also known as a physical sunblock.
- Is thicker than sunscreen, with the exception of mineral sunscreens.
- Is considered to be more effective than sunscreen because it can block a higher percentage of light.
- Can be hard to rub in.
Sunscreen:
- Consists of chemicals that absorb the UV rays.
- Works more as a chemical defense against the sun.
- Can increase your skins tolerance to UV rays, which may be beneficial if you spend a lot of time in the sun.
- Requires frequent reapplication for maximum efficacy.
- May not protect the skin as well as sunblocks with chemical ingredients.
Ingredients:
- Sunblocks usually contain zinc oxide and titanium dioxide.
- Sunscreens rely on other chemicals, such as oxybenzone or avobenzone.
Positive:
- Both sunblock and sunscreen provide protection from the suns harmful UV rays.
- Sunscreens can increase your skins tolerance to UV rays.
Negative:
- Mineral sunscreens have consistently underperformed in testing, not always testing at the claimed SPF label on the package and failing to provide adequate protection from either UVA or UVB rays.
Conclusion:
Ultimately, the choice between sunblock and sunscreen depends on individual preferences and skin type. Sunblock is generally considered to be more effective because it can block a higher percentage of light, but it can be harder to rub in. Sunscreens require frequent reapplication for maximum efficacy, but they can increase your skins tolerance to UV rays. When choosing a product, its important to read the label to ensure that it offers the level of protection you want and to avoid any ingredients that may cause skin sensitivities. Its also recommended to look for sun protection with mineral or natural ingredients instead of chemicals that can be harmful.
