Tips for choosing sunscreen

Finding the Best Sunscreen

Possess a high degree of Sun Protection Factor doesn’t mean we are free from the UV damage

SPF, or Sun Protection Factor, is a measure of how well a sunscreen will protect skin from UVB rays, the kind of radiation that causes sunburn, damages skin, and can contribute to skin cancer.

PA is approved by Ministry of Health, Labour and Welfare of Japan. It simply means Protection Grade of UVA rays. Protective grade of sunscreen is often leveled as PA+, PA++, PA+++ with the more plus sign the more protection from UVA rays.

It’s safer to apply Physical Sunscreen

Chemical sunscreens work by absorbing the sun's rays. Some chemical filters can scatter sun rays, but still mostly just absorb them. Chemical filters tend to be more irritating to skin. If it gets in your eyes, it can make your eyes sting and water. Some can cause allergic reactions. Yet, Physical Sunscreens contain active mineral ingredients, such as titanium dioxide or zinc oxide, which work by sitting on top of the skin to deflect and scatter damaging UV rays away from the skin. They are often referred to as physical blockers. It is less likely to cause a stinging irritation on the skin, making it better for sensitive skin or even for kids.

In addition, nano particle zinc oxide and titanium dioxide are controversial at the moment. Nanoparticle sized ingredients have the potential to be absorbed through the skin at a much higher rate than non-nanoparticle sized ingredients so that applying sunscreen with non-nano zinc oxide is safer. The non-nano property that ensures the zinc oxide stays on the surface of the skin providing safer and longer lasting protection.

Ingredients to avoid

1. Oxybenzone may mimic the effects of estrogen

Research indicating that oxybenzone, which blocks ultraviolet light, may mimic the effects of estrogen in the body and promote the growth of cancer cells. It might cause the skin to become more sensitive a well.

2. Retinyl Palmitate may be harmful to skin

Retinyl Palmitate may speed the development of skin tumors and lesions.

Avoid to applying sunscreen and bug repellent at the same time

Research found that the inclusion of mosquito repellent in sunscreen actually reduced the sun protection factor of the sunscreen.

Avoid to using Spray-on Sunscreen

Undoubtedly, spray-on sunscreen is very convenient for us to get to hard-to-reach spots but experts warn that inhaling the chemicals could trigger allergies, asthma and other concerns.
