UV Radiation

The sun sends out different types of radiation that reach the earth – visible light that is seen as sunlight, infrared radiation felt as heat and ultraviolet radiation (UVR) that we can’t see.
Ultraviolet radiation can be classified as UVA, UVB or UVC. The ozone layer absorbs some, but not all, of these types of UV radiation:

UVA: wavelength: 320-400nm. Not absorbed by the ozone layer.

UVB: wavelength: 290-320nm. Mostly absorbed by the ozone layer, but some does reach the Earth’s surface.

UVC: wavelength: 100-290nm. Completely absorbed by the ozone layer and atmosphere.

UVA rays account for up to 95% of the UV radiation reaching the earth’s surface, and can penetrate clouds and glass. These UVA rays play a major part in photodamage and skin ageing.

UVB rays are the chief cause of skin reddening and sunburn, damage which can also lead to premature skin ageing. Both UVA and UVB rays have the potential to cause skin cancers.

Effects of UV Radiation on the skin

Photoageing is a form or extrinsic ageing and is defined as a series of biochemical reactions that occur within the skin when it is exposed to excess UV radiation.

The visible effects can present as:

  • Hyperpigmentation (discoloured patches, age spots, solar lentigos)
  • Fine lines and wrinkles
  • Loss of collagen and elastin
  • Sallowness -a yellow discolouration of the skin

Skin cancer is a disease of the body’s skin cells. It forms when skin cells are damaged by UV radiation penetrating the skin. UV damages skin cells DNA and this can cause cells to mutate and grow abnormally. If these mutant cells are not destroyed through the body’s own processes or other means, they will continue to develop and can turn into skin cancers.

Did you know?

Australia has the highest incidence of skin cancer in the world. More than 1700 Australians die from skin cancer in each year and 2 in 3 Australians will be diagnosed with skin cancer by the time they are 70. 

Sunscreens Explained

After understanding the skin risks associated with UV exposure the importance of sun protection becomes apparent. There are a few different measures that indicate the efficacy of a sunscreen and that are recognised in Australia and regulated by the Therapeutics Goods Administration (TGA). SPF rating is one of these measures.

Sun Protection Factor (SPF) is a measure of a sunscreen’s ability to prevent UV radiation from damaging the skin. SPF measures the amount of UVB radiation transmitted to the skin after sunscreen has been applied compared to the amount of UVB transmitted to the skin without sunscreen.

A sunscreen with an SPF of 30 provides 30 times more protection than if not wearing a sunscreen. A sunscreen with an SPF of 50 provides 50 times more protection than if not wearing a sunscreen.

Broad Spectrum is another measure for sunscreens in Australia. Broad Spectrum is a measurement of a sunscreens effectiveness against UVA rays. Broad-spectrum sunscreens are designed to protect against both UVB and UVA rays. A conventional sunscreen that has an SPF rating only and does not mention the term “Broad Spectrum” may block very little UVA radiation relative to the nominal SPF.

Water resistant means that the sunscreen retains its stated SPF value after a certain time in water. The correct film of sunscreen on the skin is critical if water resistance is to be achieved. The maximum water resistant claim period of 4 hours is only allowed for products which have SPFs of 30 or more after immersion in water.

Water resistant products still need to be reapplied regularly to ensure that product has not been worn or rubbed off, eg. during towelling dry.

Introducing SunActive 50+ Range

Features complete UVA and UVB spectrum sunscreen ingredients to provide the highest UV protection with hours water resistance, antioxidant protection and touch-dry technology for a shine free velvet finish.

Optimal Sun Protection for an active lifestyle

Free of synthetic fragrances, parabens and benzophenone

Complete Spectrum Sunscreen Ingredients

The latest innovation in sunscreen research is the development of complete spectrum sunscreen ingredients. These ingredients absorb UV rays across the entire spectrum of UVA and UVB.

One of the requirements of Broad Spectrum sunscreen is for 90% of UVR rays to be absorbed up to 370nm.

Complete spectrum sunscreen ingredients protect across the entire UVA spectrum up to 400nm.

We currently stock Ultraceuticals SunActive 50+ Range

Ultraceuticals SunActive SPF50+ range contains a syngergistic blend of complete spectrum sunscreen ingredients that absorb across the entire UVA and UVB spectrum.

Powerful Antioxidant and Skin Conditioning Complex

The SunActive SPF50+ range contains a powerful antioxidant complex to help provide envirnonmental protection. Studies have also shown that some of these ingredients such as Caffeine an Feruilc Acid are helpful in protecting against UVR induced skin damage.

Skin Conditioning Complex

In order to maintain comfort and skin hydration in the harsh Australian climate, a skin conditioning complex of biomimetic moisturisation and barrier repair ingredients have been incorporated into the SunActive range.

Designed for an Active Lifestyle

Touch Dry Technology: The SunActive range features fast absorbing, touch-dry technology for a shine free, velvet finish.
4 Hour Water Resistant: The research chemists at Ultraceuticals have engineered a film that has been tested to be four hours water resistant.

In order for SunActive 50+ range to claim water resistance test the range needed to show and SPF of greater than 60 after four hours water immersion.

Low Chemical Sunscreen Load: Compared with other SPF50+ products on the market, SunActive 50+ range has a low chemical sunscreen load while providing very high sun protection and remaining photostable.

Safe for the whole family: The SunActive range does not contain parabens, synthetic dyes or fragrances or benzopehone. Designed for all skin types, SunActive can be used on adults and children alike.

How to apply SunActive 50+ Range

Apply a generous layer evenly to body and face

Apply to clean, dry skin 15-20 minutes before sun exposure and again after swimming or towelling.

If using other treatment products apply these prior to applying SunActive SPF 50+.
