Organic UV Filters


What is Organic
UV Filter?

An organic UV filter is a type of sunscreen agent that absorbs and dissipates UV radiation from the sun, thus protecting the skin from harmful effects of the sun's ultraviolet (UV) rays. Unlike inorganic UV filters (such as zinc oxide or titanium dioxide), which reflect and scatter UV rays, organic UV filters work by absorbing the UV radiation and converting it into less harmful energy, such as heat. Organic UV filters are made up of carbon-based compounds that can be either synthetic or naturally derived, and they are often used in combination with other UV filters to provide broad-spectrum protection against both UVA and UVB rays.

Advantages of Organic UV filters

  • 01

    Enhanced cosmetic elegance: Organic UV filters are more transparent and have a lighter texture than inorganic UV filters, which can often leave a white cast on the skin. This makes them more aesthetically pleasing and easier to incorporate into skincare and cosmetic products.

  • 02

    Broad-spectrum protection: Organic UV filters have a higher capacity to absorb both UVA and UVB rays, providing broad-spectrum protection against the harmful effects of the sun's radiation.

  • 03

    Photostability: Organic UV filters are more photostable than inorganic UV filters, which means they are less likely to degrade or break down when exposed to sunlight.

  • 04

    Better water-resistance: Organic UV filters are generally more water-resistant than inorganic UV filters, making them suitable for use in water-based formulations, such as swimming or beach products.

  • 05

    Flexibility in formulation: Organic UV filters can be easily incorporated into a variety of formulations, such as lotions, creams, sprays, and gels, giving formulators greater flexibility in creating different types of sunscreens.

UV & SKIN damage

UVA (320~400nm)

  • - Penetrates deep into the dermis and causes photoaging / wrinkles.
  • - Damage gradually accumulates on the skin, accelerating skin aging.
  • - Exposure to similar amounts throughout the year requires blocking throughout all four seasons.
  • Increased use of UVA blocking materials

UVB (280~320nm)

  • - Ultraviolet rays with short wavelength and high energy, the main culprit in the formation of melanin in the epidermis.
  • - It causes sunburn and erythema caused by the hot sun in summer.

PA Index : UVA blocking power, each + symbol increases by 2 times + (2 times when the sunscreen is not applied), ++ (4 times), +++ (8 times), ++++ (16 times) Meaning

SPF Index : UVB blocking power, meaning that it blocks UVB as much as [1-1/SPF index]. SPF50: 1-1/50=98% UVB blocking effect
