First of all, there may be some hormonal activity in sunscreens that could cause problems later on influencing how your body is given hormones and possibility causing cancer in the future.
Second of all, some sunscreens can cause a photo allergic reaction if you happen to be the wrong type and those sunscreens interact with you.
The third thing that sun screen can cause is some tendency to stay in the sun too long. Some people put on sunscreens, stay out on the beach for six or eight hours and although they don’t burn, they had dangerous rays that are entering the skin and could cause harmful tumors like melanoma.
Curious about natural dermatology for aging and cancer prevention? One of the reasonsthat I’m such an advocate of hats and clothing is that sun screens don’t really block the sun. They do take the sun’s energy and change it into a more harmless form of energy so that there is not a sun burn, but still some of that energy gets through. That energy can cause damage especially if you apply sunscreen on and then spend a lot of time out in the sun.
With just sunscreen, you get some of that energy coming through all day long that can be causing aging, and even potentially future skin cancer. It’s important to remember that even the metallic sunscreens like zinc and titanium are usually zinc and titanium salts, they’re not the metal. You do get some energy coming through, even using those. It’s very important to remember that you need other kinds of ways of blocking the sun. The sun screen is just an added benefit to protect against reflected rays.
The best protection against skin cancer is to protect yourself against sunburns. Sun exposure, even without burning, could possibly contribute to that, but the worst is to use sun exposures and have so much damage that the skin can’t handle it, which usually results in redness and irritations of sunburn. In order to do that, you really need to use more than just the sunscreen.
You need to time your outdoor activities if you are fair skinned, so that you are outside before 10 or 11 in the morning or after 4 in the afternoon. It is also important to be under shade such as an umbrella or overhang of a building and also to use sun protective clothing because that protects better than sunscreens.
Sunscreens should be used in addition to protecting against the reflected light from water, sidewalks or sand. This is the start of best natural skincare.
Most sunscreens have been tested and they are not likely to cause a problem, but sometimes there are problems that occur in specific individuals, and sometimes there are problems that occur way later.
So let’s talk about that for just a moment. First of all, I believe the safest sunscreens are the ones that are made from zinc and probably better, regular zinc than nano zinc. The problem with nano particles is that they can get into the skin. The good thing about zinc is it’s a very important element in the body. Now titanium in the nano form theoretically could get into the skin and get next to the DNA energy to cause damage to the DNA, but that’s never been proven. ‘
So far titanium is likely to be safe, but zinc is likely to be safer. Now that is one component part of sunscreens and those are often called sun barriers or natural sunscreens. But remember, the sunscreens even containing zinc and titanium are actually dealing with the energy, it’s not like putting a total cover across your skin, like with clothing.
The other sunscreens that are used are compounds that absorb the energy from the sun and turn it to something less harmful. Many of those compounds are related to the sulfonamide. So if you have allergy to sulfur drugs, sunscreen could be a problem for you. If you had a reaction to other sunscreens, including PABA, you still could react to some of their new sunscreens because they are similar chemically. Finally, the sunscreens that contain these various compounds may have a little bit of what we call estrogen-like activity, and so for some people they could stimulate hormone receptors and could be dangerous.
Although these kinds of things are only found out years and years after use and exposure, I prefer to avoid these kind compounds if possible. The higher potency sunscreens will contain both the zinc and/or titanium and these compounds. Take a look carefully at your labels. If you have the opportunity, find a sunscreen that avoids those kinds of chemicals, but does contain antioxidant nutrients that will give you a little bit of extra end protection.
