Yesterday at the office, I was asking my patient about her recent Hawaiian vacation experience.

Of course, like every person I talk to that spends their vacation in Hawaii, it was pure bliss.

We then got on the topic of how to pack for Hawaii and came up with the same list…


…tank top



…bathing suit

Then she mentioned something that I would never take…


I told her to leave that one at home.

Then she mentioned, “But my doctor told me that I should never go out in the sun without putting on sunscreen.”

Bad advice.

Now before you get all up and arms and want to shoot me down for saying that is bad advice, I want you to hear me out on why I don’t recommend sunscreen for my patients.

Before I get into it, let’s have some fun with a pop quiz (don’t worry, I’ll give you the answers at the end and no one will see your grade.)

1) Excessive sun exposure that results in sunburn may increase your risk of skin cancer. True/False

2) Sun exposure should be avoided completely unless you are wearing sunscreen. True/False

3) Your body is still able to produce Vitamin D if you are wearing sunscreen. True/False

Ok, here are the answers:

1) True

2) False

3) False

Although it’s true that getting a sunburn may increase your risk of skin cancer, you are making a ‘grave’ mistake by avoiding the sun altogether.

Here are the facts you need to know and I’ll let you decide whether or not to use sunscreen:

· The sun produces ultraviolet (UV) rays which come in two main wavelengths: UVA & UVB rays.

· UVA rays are the less healthy rays as they penetrate the skin deeper and cause more free radical damage.

· UVB rays are the healthy rays that help your skin produce Vitamin D.

· Excessive sun exposure, including UVA & UVB rays, is damaging resulting in sunburn which is an inflammatory response to UVA & UVB overexposure.

· However, UVB rays in the right amounts is absolutely essential to good health.

· When the UVB rays strike the surface of your skin, your skin converts the natural oil on your skin into Vitamin D3

· Vitamin D3 is absolutely mission critical to obtaining overall good health, disease prevention, and research shows it reduces your risk for cancer by as much as 60%.

· Optimal Vitamin D3 levels in the blood can help prevent at least 16 different types of cancer including ovarian, prostate and even skin cancer.

· Sunscreens may do more harm than good as they effectively protect against UVB rays & are classified into their level of sun protection factor (SPF):

SPF 15- Blocks 93% of UVB rays

SPF 30- Blocks 97% of UVB rays

SPF 50- Blocks 98% of UVB rays

So what does all this mean?


Apply sunscreen, even SPF 15, and you virtually eliminate any chance of getting Vitamin D.

Also, most sunscreens don’t filter out the more damaging UVA rays so you’re still being exposed to harmful UVA rays, even if you don’t get burned.

Here’s my other beef with sunscreen.

They contain toxic ingredients including hormone-endocrine disruptors (linked to estrogen dominance & cancer) which are absorbed in the skin to the bloodstream.

They also include Vitamin A derivatives (retinol & retinyl palmitate) which increases the speed at which malignant cells develop.

In addition, Consumer Reports recently advised parents to stop spraying their kids with spray-on sunscreens (you can smell them from a mile away) until more research is done on the dangers of titanium dioxide & zinc oxide – two key sunscreen ingredients.

I’ve dedicated a whole chapter on the subject of Vitamin D in my latest book, “The 7 Habits of Pain-Free Living!” if you want to look at this topic in more depth, but if you don’t have the time, here are a few more key points I want you to know on obtaining adequate Vitamin D3 levels in the blood:

· Make sure that you expose 40% of your body to the sun when getting your Vitamin D (keep your face covered to avoid wrinkles)

· The best time that UVB rays are at their highest is in the middle of the day, ideally between 10am-2pm.

· When your skin starts to turn the lightest shade of pink, which can occur in as little as 10-20 minutes, get out of direct sunlight. You’ve reached your limit of Vitamin D and it does not do any good to ‘bake’ longer. Your body will not make ‘more’ vitamin D.

· The darker the pigmentation of your skin, the longer time you will need to get your adequate Vitamin D levels. The lighter your skin, the less time you need in the sun.

In summary, I’ll condense my point as succinctly as I can.

The sun kicks out UVA & UVB rays. You need UVB rays to make Vit D3 which protects you against disease including cancer. Excessive sun is bad. Adequate sun (till your skin turns a light shade of pink) is good. Sunscreen blocks any chance of getting Vitamin D3.

OK, I’ve rattled long enough, but I’m very passionate about this subject as it is probably one of the easiest things you can do to stay healthy and reduce your chances of disease, including cancer.

I’ll get off my soapbox now.

Enjoy the sun this weekend and be smart when it comes to getting your Vitamin D.

Have a GREAT weekend!

Dr. Derek ‘waiting for the backlash on sunscreen’ Taylor

PS- Two weeks ago today I sent out an e-mail about having World Renown Dr. Tsui-Tsair Chi giving a seminar on Saturday, September 30, 2017 from 12:00-1:30pm at the South End Tennis Club titled:

“How To Use Fingernail & Tongue Analysis to Reduce Your Chance of Diseases such as Cancer, Heart Disease, Hormone Problems, Etc!”

The cost of the seminar lecture is FREE!

He will also be doing evaluations for my patients and there are only 2.5 more days to sign up before the early bird registration discount is gone.

The response has been INCREDIBLE and almost all the evaluation times are taken. There are a few spots left.

If you would like to be evaluated by Dr. Chi on the day of the seminar, the cost of the evaluation is $79. Early bird registration till September 4th (Labor day) is $59 for the general public and $49 for anyone who has ever been a patient.

You won’t regret your decision to meet Dr. Chi and it could be life-saving for some. Call to reserve your spot today at 310-891-0102.

Who is Dr. Chi?

Dr. Chi, NMD, PhD, had medical training in China; he earned his Ph.D. in Biochemistry from Waksman Institute of Microbiology at Rutgers State University, New Jersey in 1978. Dr. Chi then became a Board Certified Naturopathic Physician. Since then, he has done infectious disease work at E.R. Squibb and sons, Inc. New Jersey, and cancer screening work at Warner-Lambert / Park-Davis Co. in Michigan. He was also the laboratory director at Omicron Incorporated in Redlands, California where he worked in the fields of cancer and atherosclerosis.

Dr. Chi had been closely associated with the late Virginia Livingston, M.D. and he developed a California stated licensed Neostop (trademark) Anti-Tumor Vaccine for poultry. Dr. Chi has also attained a patent for the detection of antibodies against a chorionic gonadotropin-like substance, and has been a consultant to many pharmaceutical companies and clinical offices in the United States, European countries, China, Taiwan, Japan, and Southern Asian Countries.

Dr. Chi’s father was a doctor for 45 years and Dr. Chi himself has had over 37 years of experience in the field. Together, he has been able to combine both eastern and western methodologies as he has observed the conditions of tens of thousands of cancer patients all over the world.
