Sunblock, our skin’s ultimate protector
What is a sunblock?
Sunblock implies a cream or lotion for skin protection from the sun and preventing sunburn. Protective lotions can be chemical and physical. Sunblock is the physical kind. It contains ingredients that stay on top of the skin creating an actual barrier between your skin and damaging UV rays.
Difference between sunblock and sunscreen
Sunscreens protect your skin against UVA rays, while sunblock traditionally protects your skin against UVB rays. Fortunately, modern industry combined those two and now we can enjoy a perfect mixture for almost perfect protection. Almost perfect because no sunblock or sunscreen can protect from all sun rays and its consequences. If you want to seriously protect yourself, combine clothing, or even sun protective clothing, hats, umbrellas, and limit your sun exposure.
Lotions are not enough
Lotions are an important measure for protecting your skin, but they are only a part of the solution. A study showed that people using sunscreen were at a higher risk for developing melanoma. This is likely due to increased time sunbathing when applying sunscreen.
Adding lotions to your daily routine can block UVA, promoting graceful aging, and UVB, which can keep your skin from burning. Choose a sunblock that has an SPF of 30 or higher. Higher number SPFs offer slightly more protection, but also contain more chemicals. And there’s no scientific evidence that using a sunscreen with a 50+ SPF is better than sunscreen with an SPF of 50.
What is SPF?
Most sunscreens with an SPF of 15 or higher do an excellent job of protecting against UVB. SPF, or Sun Protection Factor, is a measure of a sunscreen’s ability to prevent UVB from damaging the skin. If the bottle says SPF 15 in means that product gives you the opportunity to expose to the sun 15 times more than you would without any protection. If your skin gets red after 20 minutes in the sun, then SPF 15 gives you 15×20, equals 300 protected minutes in the sun.
Don’t economize with your lotion
When you apply sunblock, don’t be cheap. Some say that one ounce, or a size of a shot glass is recommended daily amount of sun lotion. Statistics say that only 20%-50% people use the recommended amount of sunblock, diminishing the quality of protection received. So, fill your entire palm and apply in thick layer. Make sure to cover all the areas equally and allow time for absorption.
Tips on choosing and using sunblock:
- Make sure your product contains UVA and UVB rays protection
- Choose one that has an SPF of 30 or higher
- Look for products with octyl methoxycinnamate, octyl salicylate and octocrylene

- If you are swimming or sweating abundantly reapply every two hours
- Be careful about the ingredients, take care of your allergies or irritations, choose products without harmful parabens
- Use it generously and liberally
