Sunscreen
Toxic chemicals in commercial sunscreen cause cancer, multiple sclerosis, and lupus by poisoning the skin's fat-conversion mechanism. When dietary fat intake is adequate, solar radiation converts beneficially into vitamin D and protective cholesterols; no sunscreen is needed.
Sunscreen chemicals represent one of the most consistently condemned categories of commercial products in Aajonus Vonderplanitz's framework. His position was not that the sun is dangerous and sunscreen insufficiently effective, but the precise opposite: the sun causes no damage to a body with adequate fat reserves in the skin, and sunscreen is itself a source of serious disease. He described sunscreen as "very toxic" and stated unambiguously that sunscreen causes cancer, not the sun it is meant to block. This understanding flowed directly from his model of how solar radiation interacts with the skin, which depends entirely on the presence of appropriate fats.
In Aajonus's framework, the sun's rays strike the oils and fats residing in the skin and convert them into vitamin D, along with a complex array of cholesterols and fats that serve functions throughout the body including structural strength, protection, and energy. When the skin has adequate fat, solar radiation is absorbed beneficially, converted, and then tanned into the skin. When the skin is fat-deficient, either from eating insufficient raw fat, from an inability to utilize cooked and processed fats, or from the application of any skin lotion including suntan lotions, the radiation cannot be converted and instead burns and blisters the skin. Sunscreen, by smothering the skin and introducing chemical poisons into it, actively destroys the fat-based mechanism that the skin depends on to use sunlight productively. This is why, in his view, people who use sunscreen are more prone to cancer, not less.
The toxicity he attributed to sunscreen was not generic or incidental. He named specific disease outcomes, stating that sunscreen causes cancer in the lymph system, cancer in the connective tissue, skin cancer, multiple sclerosis, and lupus, which he described as disintegration of the connective tissue. These were not presented as theoretical risks but as observed outcomes consistent with his broader understanding of how industrial chemicals accumulate in specific tissues and cause those tissues to break down.
Sunscreen Blocks Natural Skin Function
The skin's ability to convert solar radiation into vitamin D depends on the presence of raw, unconverted fats in the outer layers. Aajonus described a precise process: solar radiation hits the fat on the skin, the skin converts those rays together with the fat into vitamin D, and that vitamin D is then distributed throughout the body for a wide range of biological functions. When someone is highly toxic, the body draws fat away from the skin to bind with internal poisons, leaving the skin depleted and bare. In this fat-depleted state, the sun will burn and blister rather than tan.
Sunscreen interrupts this process in two ways. First, its chemical constituents poison and smother the skin, preventing the natural oils from performing their conversion function. Second, because the chemicals in sunscreen penetrate the skin, they enter the body and contribute to the very toxicity that depletes fat from the skin in the first place. The result is a feedback loop: the more sunscreen used, the more chemically toxic the body becomes, the more fat is diverted away from the skin, and the more vulnerable the skin becomes to solar damage. This is the mechanism Aajonus described when he said that sunscreen causes cancer rather than preventing it.
He also noted that washing the body the morning before sun exposure compounds the problem by removing the skin's own natural oils, which serve as a natural sunblock. His instruction was explicit: do not shower or bathe the morning of a day of sunbathing, because washing removes the body's protective oil layer.
Cancer MS And Lupus
Aajonus stated directly: "You don't need sunscreen if you're eating properly. Well, sunscreen is very toxic. Very toxic. In fact, sunscreen causes a lot of cancer. It causes MS, multiple sclerosis, and it causes lupus, which is disintegration of the connective tissue." These disease attributions follow from his consistent model that industrial chemicals deposited in specific tissues cause those tissues to deteriorate in characteristic ways. Lymphatic cancer, connective tissue cancer, and skin cancer are named as outcomes.
The lupus attribution is particularly specific. In his framework, lupus represents chemical-induced disintegration of connective tissue, and he placed sunscreen chemicals among the agents capable of producing this outcome. Multiple sclerosis similarly reflects what happens when toxic chemicals penetrate and damage the nervous system and its fatty sheaths, which correlates with his general model of how industrial chemical exposure produces neurological disease.
He supported his broader argument about sun safety by pointing to populations such as Africans and Asians working in rice fields who receive intense, lifelong sun exposure without developing cancer or wrinkled skin, arguing that if the sun itself were the carcinogenic agent, these populations would universally show cancer and severe skin damage. The fact that they do not, in his view, proves that sun exposure is not the cause. Skin cancer, in his framework, is a product of chemical toxicity in the body expressed through the skin, combined with fat deficiency that prevents proper solar conversion.
What to Use Instead
Because sunscreen is ruled out entirely, Aajonus developed specific natural formulas for sun protection and tanning. His recommendations evolved over time and he acknowledged in the source material that he had experimented with many approaches.
For a sunblock, he identified coconut cream as the primary option, noting that it must be applied the night before sun exposure rather than immediately before, because the high oil content of coconut cream (approximately 78% oil) will otherwise function as a tanning agent by drawing more solar radiation into the skin. When applied the night before, the oils absorb into the skin and the cream shifts to providing a protective, whitening effect. He noted personally that using coconut cream regularly kept him whiter than he wanted and required him to spend more time in the sun to achieve a tan, though he framed this as a positive outcome because it allowed greater vitamin D accumulation.
For tanning specifically, plain coconut oil is rubbed into the skin to draw more sun in and accelerate tanning.
Milk applied directly to the skin was also identified as an effective sunblock. Aajonus described rubbing or breathing pure milk onto the skin as something that "completely blocks the sun," stating that even if the skin turns very red, the redness will resolve within a day.
His most developed formula, which he described as something he arrived at within the last six months of one seminar, was a compound skin preparation combining equal parts of coconut cream, raw butter, and raw cream, with small additions of raw honey and royal jelly. The exact proportions for an eight-ounce jar were: two ounces butter, two ounces raw cream, two ounces coconut cream, half a teaspoon of honey, and one-eighth teaspoon of royal jelly. He emphasized that none of these ingredients works correctly in isolation for this purpose: coconut cream alone will cause burning, raw cream alone will cause burning, butter alone will cause burning. Only the combined formula functioned both as a tanning agent and as a sunblock in his testing. He described warming all ingredients together in a jar immersed in warm water until melted, then blending for approximately 20 seconds. When prepared this way, the mixture sets to a firmer, more butter-like consistency. When prepared cold, it becomes more like a commercial face cream. He noted that the warm-prepared version lasts longer.
He also cited testing of the skin cream formula described in "The Recipe for Living Without Disease," noting that during sunscreen-potential tests, participants who expected to burn instead showed no burn or soreness the following morning and did not peel, while participants who normally did not tan were able to tan.
Natural Skin Fats Cause Problems
Aajonus noted an important edge case: some individuals, particularly those with significant accumulated toxicity, may not tolerate any externally applied fats on their skin prior to sunbathing, including butter and cream mixtures. In his own case, he stated he could not put any oil on his skin for 24 hours before sun exposure and could not bathe for 24 hours prior to sunning. In this state, he would feel burned for a day after sun exposure, but that feeling would fade to a tan without peeling.
He attributed this to having sufficient internally transported fats in the skin that external applications of fat actually disrupted the process rather than supporting it. For the first outing of each season, he noted that some burn with peeling might occur. After the first burn of each year, burning becomes rare. If burning and peeling continues through two or more outings, he interpreted this as a possible sign that the person already has enough oil in the skin and should not apply any external fats before sunning.
He regulated initial sun exposure at no more than 20 minutes per side per flip for the first outing.
He described a client with red hair and very white skin who had been on the diet for nearly ten years but had previously always experienced second-degree or worse sunburning and feared sun exposure because of a cancer history. She spent several hours on a beach without any prior oil application, turned bright red, felt very sore, and applied raw cream to soothe the burning feeling for 36 hours. After three days, all redness and soreness had resolved without any peeling, which Aajonus noted was the first time in her 42 years this had happened.
The Albino Case
Aajonus described an albino individual he encountered at a yoga ashram in 1974 who had never been able to tolerate sun exposure due to extreme skin sensitivity. He worked with this person using butter and natural preparations that allowed the individual to build up sun tolerance despite lacking normal skin pigmentation. This case was presented as evidence that even the most sun-sensitive individuals can adapt to sun exposure through dietary and topical support rather than chemical sunscreen.
What to Do After Burning
For sunburn that does occur, Aajonus offered several remedies. Rubbing tomato directly on burned areas was one option. A mixture of water and a small amount of honey, specifically one part honey to ten parts water, was another option, though he noted it is sticky. Raw cream applied to burned skin soothes and nourishes the skin and helps it absorb the sun radiation already captured in the skin. Aloe vera gel taken directly from the plant, not from commercial preparations, was described as soothing for radiation-type burn including sunburn. He also referenced the Primal Facial Body Care Cream formula and a mixture of two tablespoons fresh raw aloe gel, one-sixth teaspoon fresh royal jelly, one-quarter teaspoon sun-dried powdered clay, and one teaspoon stone-pressed olive oil as topical applications for sunburn. Raw egg white applied to sunburn was described as another effective option.
Butter was specifically mentioned by seminar participants and confirmed by Aajonus as the most effective agent for preventing burn and accelerating healing after sun exposure, working faster than other options. Coconut oil applied the following night and aloe applied the day after that were described as part of a layered post-sun recovery protocol.
The Broader Framework
Aajonus placed sunscreen chemicals within his larger framework of industrial chemical accumulation as the root cause of most degenerative disease. The specific chemicals in sunscreen are not always named in his presentations, but his framework treats all skin lotions, including suntan and sunscreen products, as agents that smother and poison the skin, disrupting its function as an organ of detoxification, vitamin D synthesis, and fat conversion. He grouped them with other toxic personal care products including commercial soaps, cosmetics, and deodorants, all of which he viewed as introducing industrial chemicals through the highly permeable skin.
His repeated position was that no one eating properly needs sunscreen. The need for sunscreen arises from chemical toxicity that depletes the fats from the skin and prevents proper solar conversion, and sunscreen then worsens that underlying condition while appearing to address its symptom. He described the sun itself as presenting no damage to a properly nourished body, pointing to free-living traditional populations as evidence.
