Sunburn is caused by radiation from the sun, not by the heat from the sun. Two distinct wavelengths of ultraviolet (UV) light are emitted by the sun, and each has distinct detrimental effects. We refer to these wavelengths as UVA and UVB.
Shorter wavelength UVB rays are responsible for the most visible indicators of skin damage, such as redness and blisters, which are frequently common to cases of skin cancer. According to medical professionals, extended exposure to UVB rays is directly responsible for up to four out of every five incidences of skin cancer.
With a longer wavelength, UVA damages cells by penetrating the skin deeply. This exposure frequently causes wrinkles, skin discoloration, and premature aging. Even while UVA radiation is recognize by professionals as a major concern, many customers choose to ignore it.
According to a recent survey by titanium dioxide manufacturer, the majority of parents would select a sunscreen only based on its sun protection factor (SPF) rating, disregarding the harm that ultraviolet A radiation may inflict.
Which type of sunscreen filter is best, chemical or mineral?
To guard against the damaging effects of the sun, all sunscreen lotions use active components in the form of chemical or mineral filters. A mineral filter that offers protection from UVB and UVA rays is titanium dioxide (TiO₂). While certain biological filters are precise to covering specific wavelengths, TiO2 functions as a broad-spectrum filter. Thus, shielding the skin from blue light, which can be damaging.
In contrast to chemical sunscreens, which are absorbing into the skin and alter UV photons that enter the body by changing them into infrared rays, mineral sunscreens, including TiO2, create a protective coating on top of the skin and reflect UV radiation. Concurrently, TiO2 is
TiO2 in nanoform is more easily applicable and undetectable
TiO2 in nanoform has been a revolutionary development that has found widespread application in sunscreen because, in contrast to bigger particles of TiO₂, it is transparent rather than white and yet provides UV protection. By doing this, an irritating white coating of cream on the skin is avoidable. It also simplifies and lessens the frustration of applying.
Titanium dioxide cosmetic grade manufacturers provide and extra advantage of being more easily absorbing and transparent in nanoform, which lessens whiteness. These are significant advantages since a person’s decision to use sunscreen to protect oneself from the sun may have an impact by how a product feels and appears on their skin.
Defense against infrared radiation
Moreover, titanium dioxide that has micro-sized crystals shields against infrared light. This is relatively new to sunscreens and has been useful in industrial settings for a long time. It is quite efficient in shielding the skin from damaging infrared radiation.
Mineral sunscreens are the preferred choice for parents and those with sensitive skin due to their advantages over chemical sunscreens. Chemical alternatives can “cause skin irritation and allergies, need to be reapply more frequently. They are absorb by the skin to a much greater extent,” according to Paul Wright, an associate professor at RMIT University’s School of Health and Biomedical Sciences.
