Are the Ingredients in Sunscreen Safe?

Posted on:

One of the most recommended products by aestheticians and dermatologists is sunscreen, but the FDA has found that the active chemicals in sunscreen is easily absorbed by the skin. The studies found that although they absorbed into the skin, it cannot be confirmed whether this is safe or not, which means more research needs to be done. The study’s goal was to see if they could find 0.5 nanograms per milliliters of sunscreen chemicals in the blood, which they did. The FDA has already concluded that mineral sunscreens, such as those composed of zinc oxide and titanium oxide, are safe. The one downside to these mineral sunscreens is that they often leave a white cast after application. The study performed by the FDA tested 6 chemical sunscreen ingredients from four different formulations- 3 of which were  sprays and one was a lotion. The chemicals that were tested were homosalate, octisalate, octinoxate, avobenzone, octocrylene, and oxybenzone. The participants applied sunscreen over 75% of their body once a day on the first day, and then four times a day for three days. It was found that all six chemicals exceeded the FDA’s 0.5 nanograms per milliliters in the bloodstream, and continued increasing over the course of the experiment. The main takeaway was that they found out how much of these chemicals is getting in the bloodstream, however new studies need to be conducted to find out if this information is relevant or not. This study does not suggest you stop applying sunscreen, however if you are concerned by the outcomes you can always opt for a mineral sunscreen. sunscreen image

Vitamin D is often associated with strong bones. The major biological function of Vitamin D is to keep the serum calcium and phosphorus concentrations within the normal range which maintains essential cellular functions and promotes mineralization of the skeleton. But more is not necessarily better. Research has found that those who take large amounts of vitamin D not only did not see any benefits in regards of bone density, but actually ended up with worse bone density in the long run.

It has been found that high doses of vitamin D do not provide additional benefits for bone health. There are are a few instances where doctor’s believe higher doses of vitamin D are beneficial with those that have conditions that prevent the body from absorbing nutrients properly: ulcerative colitis and Crohn’s disease. But increasing vitamin D in hopes your bones will be stronger, is not recommended for most people.

There are simple tactics you should follow to maintain your bone health. It is safe and sensible to take small amounts of vitamin D, like 1,000 International Units (IU), if you believe that you are not getting enough of this vitamin naturally. Get tested to see if you have sufficient vitamin D. Supplements are best for those who consume a small amount of vitamin D in their diet but it is recommended that you get vitamin D through diet and sun exposure rather then supplements, when possible. Some good sources of vitamin D are cheese, milk, yogurt, fatty fish like tuna or salmon, and cereals. People that don’t spend a lot of time outdoors should also consider taking small doses of vitamin D supplement. This vitamin is often referred to as the “sunshine vitamin” as it is produced by your body after exposure to the sun. As you get older, your body produces less and less vitamin D. People that are over the age of 65 make about 25% of the vitamin D they did in their twenties. Doses of vitamin D 4,000 IU or higher should only be taken under the advice of your primary care physician. In rare cases, a high dosage can actually be toxic. It can even lead to hypercalcemia, which is a condition that causes high amounts of calcium build up in the blood. This condition could cause a formation of deposits in soft tissues or arteries. It could also cause a predisposition to kidney stones, which are pebble like masses, created when high levels of minerals in your urine begin to crystallize in the kidneys. Again, the preferable method of getting your vitamins and minerals is through your diet. You can check food labels on the back of packaged foods to see the amount of vitamin D they contain.

The thyroid a large ductless gland in the neck which secretes hormones regulating growth and development through the rate of metabolism.  Metabolism is our body’s ability to convert food into energy and the energy is burned at different rates depending on the person.  

The interconnectivity of the hormones, organs and the brain must be in sync for optimal performance.  So if the thyroid gland is not functioning correctly, you may experience symptoms of a thyroid disorder: underactive or overactive.  Low levels of the thyroid hormone, hypothyroidism, could cause various symptoms such as dry skin, changes in your hair, brittle nails, constipation, fatigue, and aches/pains. If low levels of this hormone remain untreated, it can increase the likelihood high blood pressure, high cholesterol and heart disease. High levels  of thyroid hormone, hyperthyroidism, occurs when the thyroid gland produces too much of the thyroxine hormone.   Too much of this hormone can accelerate your body’s metabolism which may cause weight loss or rapid/irregular heartbeat.

In some cases, symptoms can be gradual and not very noticeable, and in other cases symptoms can be abrupt within a few weeks or months. Symptoms can include exhaustion, depression, constipation, muscle aches, cardiovascular effects, cold intolerance, and appetite loss. Please consult a physician if you experience any of these symptoms. Hypothyroidism is typically treated with a daily dose of synthetic hormone, in pill form, and essentially does the job of your thyroid. Usually, people with hypothyroidism experience a substantial symptom relief after starting this treatment.  Hyperthyroidism can be treated using anti-thyroid medications and radioactive iodine to slow the production of thyroid hormones. Sometimes, hyperthyroidism treatment involves surgery to remove all or part of your thyroid gland.
