When people who produce less melanin are overexposed to UV rays, it causes damage to the DNA in the upper layers of skin cells—resulting in a radiation burn, known as sunburn. Not everybody responds in the same way to sun exposure. In general, people with lighter skin, freckles, or nat...
How long does sunscreen last on your face if you have makeup on? Some makeup, such as foundations, naturally offer a sun protection of around 3 or 4 SPF. This is very low, so you’ll still need to wear sunscreen under your makeup if you’re going out into the sun. If your fou...

The damaging effects of UV radiation from direct exposure to the sun is the most common cause of tire sidewall cracking. We keep our tires covered as often as reasonably possible, and you should, too. More on that below. Proper Tire Inflation ...
Liposomes are very important as drug carrier systems due to many factors including their suitability to encapsulate polar and non polar drugs, their stability and long shelf life, controllable properties such as size and charge, ability to functionalize and modify the surface due to the presence of...
This multi-functional ingredient is used to create a long-lasting, non-caking makeup product. Because it can absorb moisture and sweat and prevent light reflection, this ingredient is called an absorbent. This is a requirement in comprehensive applications. FDA approved it for use as an anti-...
How can you determine the biological effects of radiation exposure? Radiation: Radiations which are not ionizing are considered to have long wavelength. Ionizing radiations are radiations possessing huge amount of energy. Radiowaves, infrared and gamma radiations are some kinds of radiation. ...
Long-term exposure to weightlessness causes our bodies to lose calcium from bones, tissue from muscles and fluids from our body. These effects of weightlessness — such as decreased muscle strength, osteoporosis — are similar to the effects of aging. So, exposure to microgravity may give us new...
