How Much Sun Screen Do You Need?

We all need some sun exposure because it’s our primary source of vitamin D, which helps us absorb calcium for stronger, healthier bones. But it doesn’t take much time in the sun for most people to get the vitamin D they need, and repeated unprotected exposure to the sun’s ultraviolet rays can cause skin damage, eye damage, immune system suppression, and skin cancer. Even people in their twenties can develop skin cancer.

The sun, a six billion-year-old star, is currently still the center of confusion regarding its effects on the skin. The sun radiates visible light, which gives us the color we see; infrared light, which gives us the warmth we feel ultraviolet (UV) light, which we cannot see.

When UV radiation reaches the skin, some radiation is reflected away from the surface.  Some radiation is also absorbed and scattered into the tissue just beneath the skin’s surface. The skin’s living cells absorb a proportion of this radiation. UV radiation absorbed by living cells can result in damage to the skin such as: sunburn, aging of the skin, and skin cancer. However, vitamin D synthesis relies on UV radiation and is essential for the body. Some scientists believe that vitamin D prevents skin cancer.

So, does sun cause or prevent skin cancer?

Compounded on the questionable effects of sun on the skin regarding skin cancer, is the questionable safety of sunscreens. For example, the reflectors Titanium Dioxide and Zinc Oxide in nano particle size and almost all UV absorbers have been shown to have adverse effects on the body.

Most kids rack up a lot of their lifetime sun exposure before age 18, so it’s important that parents teach their children how to enjoy fun in the sun safely. Children get 80% of their lifetime sun exposure before the age of 18, so protection is important. Teens and people below 40 years should use a broad-spectrum sunscreen with SPF30-50 and use sunsmart protective clothing.

So what precautions should we take to prevent skin cancer?

The key to effectively protect the skin from skin cancer is to find a healthy balance between getting enough natural sunlight to maximize vitamin D production and obtain optimal health, while at the same time protecting the skin from damage that occurs from over-exposure to the sun.

The following precautions are recommended:

·      Generally skin cancers appear in adults over the age of 40.  Additional care is required at this stage.  Recently a treatment for skin cancers has been reported using natural BEC glycoalkaloids in a cream CuradermBEC5.  Various scientific publications show that when skin cancers were eliminated by this therapy, histologically by biopsies, and over 5 years follow-up, that there were no recurrences. Subsequently it was reported that BEC glycoalkaloids, when added to a specific sunscreen formulation with a broad spectrum and SPF 3, CurasolBEC had many additional benefits and that this sunscreen could eliminate very early precancerous and cancerous growths.  Accordingly, CurasolBEC sunscreen as a preventative for skin cancers is recommended for persons of all ages especially those over 40 years.

·      For infants under 6 months – Keep out of the sun and especially avoid exposure to the sun in the hours between 10am and 2pm when UV rays are most intense.  Dress infant in lightweight long pants, long-sleeved shirts and brimmed hats that shade the neck. The skin of babies is less mature compared to adults, and infants have a higher surface-area to body-weight ratio compared to older children and adults.  These factors mean that an infant’s exposure to the chemicals in sunscreens (as discussed above) may be much greater, increasing the risks of side effects from the sunscreen. So, infants should not use sunscreens that contain potentially toxic ingredients.  Barrier sunscreen with Titanium or Zinc Oxide that or not micronized can be considered only on areas prone to the sun.  These sunscreens appear white on the skin when used.

·      Teenagers – Encouraging teenagers to use sunscreens is more effective by highlighting the effects of sunscreen usage on the prevention of premature wrinkling and ageing rather than precaution of skin cancer.  Highlighting consequences to appearance rather than health appear to be more effective with teenagers. The fact that teens are motivated by beauty to use sunscreens limits their use of non-micronized Zinc and Titanium oxides, as these sunscreens are visible as white when applied to the skin.

Bill E. Cham, PhD holds degrees in Chemistry (University of Delft, The Netherlands), Biochemistry and a Doctorate in the School of Medicine (Queensland University, Australia). The varieties of his chosen degrees have enabled him to have a wide approach to research, exactly what was needed with the development of the BEC anticancer technology. This background has enabled Dr. Cham to have an open mind and a non-tunnel vision to science. He has published over 100 articles. His first book, The Eggplant Cancer Cure: A Treatment for Skin Cancer and New Hope for Other Cancers from Nature’s Pharmacy (2007) received worldwide attention and acclaim. He is the founder of CuradermBEC5 and consults worldwide for Curaderm Global LTD.  He currently resides on the island of Vanuatu but has resided in Australia for over 30 years where he still conducts his ongoing research.
