Early civilizations used a variety of plant products to help protect the skin from sun damage. For example, ancient Greeks used olive oil for this purpose, and ancient Egyptians used extracts of rice, jasmine, and lupine plants whose products are still used in skin care today. [15] Zinc oxide paste has also been popular for skin protection for thousands of years. [16] Among the nomadic sea-going Sama-Bajau people of the Philippines, Malaysia, and Indonesia, a common type of sun protection is a paste called borak or burak, which was made from water weeds, rice and spices. It is used most commonly by women to protect the face and exposed skin areas from the harsh tropical sun at sea. [17] In Myanmar, thanaka, a yellow-white cosmetic paste made of ground bark, is traditionally used for sun protection. In Madagascar, a ground wood paste called masonjoany has been worn for sun protection, as well as decoration and insect repellent, since the 18th century, and is ubiquitous in the Northwest coastal regions of the island to this day. [18] [19] One-star products provide the lowest ratio of UVA protection, five-star products the highest. The method was revised in light of the Colipa UVA PF test and the revised EU recommendations regarding UVA PF. The method still uses a spectrophotometer to measure absorption of UVA versus UVB; the difference stems from a requirement to pre-irradiate samples (where this was not previously required) to give a better indication of UVA protection and photostability when the product is used. With the current methodology, the lowest rating is three stars, the highest being five stars.

In August 2007, the FDA put out for consultation the proposal that a version of this protocol be used to inform users of American product of the protection that it gives against UVA; [78] but this was not adopted, for fear it would be too confusing. [81] PA system [ edit ] Studies have shown that sunscreen with a high UVA protection factor enabled significantly higher vitamin D synthesis than a low UVA protection factor sunscreen, likely because it allows more UVB transmission.

Sun protection factor and labeling [ edit ] Two photographs showing the effect of applying sunscreens in visible light and in UVA. The photograph on the right was taken using ultraviolet photography shortly after application of sunscreen to half of the face. It is known that SPF is affected by not only the choice of active ingredients and the percentage of active ingredients but also the formulation of the vehicle/base. Final SPF is also impacted by the distribution of active ingredients in the sunscreen, how evenly the sunscreen applies on the skin, how well it dries down on the skin and the pH value of the product among other factors. Changing any inactive ingredient may potentially alter a sunscreen's SPF. [118] [119]

Numerous methods have been devised for evaluation of UVA and UVB protection. The most-reliable spectrophotochemical methods eliminate the subjective nature of grading erythema.

Cetaphil’s sunscreen is formulated to be gentle enough for the sensitive skin on your face but can be used to protect your body, too. Though the bottle is small, we found that a little bit of this formula goes a long way. So don’t be shy about reapplying it anywhere you need sun protection. Sunscreens must include standardized "Drug Facts" information on the container. However, there is no regulation that deems it necessary to mention whether the contents contain nanoparticles of mineral ingredients. Furthermore, US products do not require the expiration date of products to be displayed on the label. [159]

Some studies have shown that people commonly apply only 1/4 to 1/2 of the amount recommended for achieving the rated sun protection factor (SPF), and in consequence the effective SPF should be downgraded to a 4th root or a square root of the advertised value, respectively. [85] A later study found a significant exponential relation between SPF and the amount of sunscreen applied, and the results are closer to linearity than expected by theory. [148] Some studies show that mineral sunscreens primarily made with substantially large particles (i.e., neither nano nor micronized) may help protect from visible and infrared light to some degree, [138] [124] [140] but these sunscreens are often unacceptable to consumers due to leaving an obligatory opaque white cast on the skin. Further research has shown that sunscreens with added iron oxide pigments and/or pigmentary titanium dioxide can provide the wearer with a substantial amount of HEVL protection. [124] [141] [142] [143] Cosmetic chemists have found that other cosmetic-grade pigments can be functional filler ingredients. Mica was discovered to have significant synergistic effects with UVR filters when formulated in sunscreens, in that it can notably increase the formula's ability to protect the wearer from HEVL. [136]

There is a growing amount of research demonstrating that adding various vitamer antioxidants (eg; retinol, alpha tocopherol, gamma tocopherol, tocopheryl acetate, ascorbic acid, ascorbyl tetraisopalmitate, ascorbyl palmitate, sodium ascorbyl phosphate, ubiquinone) and/or a mixture of certain botanical antioxidants (eg; epigallocatechin-3-gallate, b-carotene, vitis vinifera, silymarin, spirulina extract, chamomile extract and possibly others) to sunscreens efficaciously aids in reducing damage from the free radicals produced by exposure to solar ultraviolet radiation, visible light, near infrared radiation and infrared-a radiation. [120] [144] [134] [124] [145] [122] [125] Since sunscreen's active ingredients work preventatively by creating a shielding film on the skin that absorbs, scatters, and reflects light before it can reach the skin, UV filters have been deemed an ideal “first line of defense” against sun damage when exposure can't be avoided. Antioxidants have been deemed a good “second line of defense” since they work responsively by decreasing the overall burden of free radicals that do reach the skin. [136] The degree of the free radical protection from the entire solar spectral range that a sunscreen can offer has been termed the "radical protection factor" (RPF) by some researchers. On 1 January 2020, Palau banned the manufacturing and selling of sun cream products containing any of the following ingredients: benzophenone-3, octyl methoxycinnamate, octocrylene, 4-methyl-benzylidene camphor, triclosan, methylparaben, ethylparaben, butylparaben, benzyl paraben, and phenoxyethanol. [150] The decision was taken to protect the local coral reef and sea life. [151] Those compounds are known or suspected to be harmful to coral or other sea life.

In the 2010s & 2020s, there has been increasing interest in sunscreens that protect the wearer from the sun's high-energy visible light& iinfrared light as well as ultraviolet light. This is due to newer research revealing blue & violet visible light and certain wavelengths of infrared light (e.g., NIR, IR-A) work synergistically with UV light in contributing to oxidative stress, free radical generation, dermal cellular damage, suppressed skin healing, decreased immunity, erythema, inflammation, dryness, and several aesthetic concerns, such as: wrinkle formation, loss of skin elasticity and dyspigmentation. [132] [133] [134] [135] [136] [137] [138] Increasingly, a number of commercial sunscreens are being produced that have manufacturer claims regarding skin protection from blue light, infrared light and even air pollution. [138] However, as of 2021 there are no regulatory guidelines or mandatory testing protocols that govern these claims. [124] Historically, the American FDA has only recognized protection from sunburn (via UVB protection) and protection from skin cancer (via SPF 15+ with some UVA protection) as drug/medicinal sunscreen claims, so they do not have regulatory authority over sunscreen claims regarding protecting the skin from damage from these other environmental stressors. [139] Since sunscreen claims not related to protection from ultraviolet light are treated as cosmeceutical claims rather than drug/medicinal claims, the innovative technologies and additive ingredients used to allegedly reduce the damage from these other environmental stressors may vary widely from brand to brand. SPF Level: Dr. Ilyas says she always recommends that her patients use sunscreen with an SPF of at least 30 and look for those that offer broad-spectrum coverage against both UVA and UVB rays. But keep in mind that when it comes to mineral sunscreen, the higher the concentration of zinc oxide or titanium dioxide, the better. Some experts believe that mineral sunscreen is generally less effective than chemical sunscreen, but obviously, if you have sensitive skin or frequently react to the ingredients in chemical sunscreens, mineral sunscreen may be your best bet for sun protection. Aim for a formula that has at least 10% titanium dioxide or zinc oxide or both—they boost one another’s effectiveness.
