LEADING DERMATOLOGISTS AGREE:
LONG UVA RAYS ARE MORE ABUNDANT AND PENETRATE DEEPER THAN OTHER UV RAYS
Kiehl’s UV protection with a new triple UV defense against skin aging
It is widely understood that sunscreens are critical to protecting skin from the damaging effects of the sun. In fact, according to the Skin Cancer Foundation, more than 90% of the visible changes commonly attributed to skin aging are caused by the sun. These damaging effects are from UVB as well as long and short UVA rays that are known to encourage premature skin aging.
Inspired by this insight, Kiehl’s now offers a more advanced solution to sun protection – introducing the new and improved Dermatologist Solutions Ultra Light Daily UV Defense SPF 50 PA++++ (30ml, $52 and 60ml, $82). This ultra-lightweight formula employs a unique blend of sunscreen filters that now extend protection beyond short UVA rays to provide enhanced protection against the equally harmful long UVA rays that are more abundant and penetrate deeper into the skin. Combined with the antioxidant power of Vitamin E, the formula helps protect against all three forms of skin damaging UV rays that reach the earth’s surface .
THE TWO TYPES OF UVA
Most of us are exposed to large amounts of UVA throughout our lifetime. In contrast to UVB rays that are more present in the summer and around noon, UVA radiation is present year round, from sunrise to sunset, and is 30 – 50 times more common . These ultraviolet rays are categorized by their wavelength:
- UVB rays are shorter than UVA ranging from 290 – 320 nanometers
- UVA rays are the longest, measuring 320 – 400 nanometers
UVA can be further divided into two wave ranges:
- Long UVA rays, which measure 340-400 nanometers
- Short UVA rays which extend from 320-340 nanometers
Both long and short UVA rays can pass through clouds and glass to cause photoaging , which can appear as wrinkles, roughness, lack of elasticity or hyperpigmentation. However, long UVA rays extend much further, reaching and therefore damaging the deepest layers of the dermis .
“While the surface and upper layers of the skin are equipped with certain defenses that may mitigate some aspects of photoaging, long UVA rays penetrate to the deepest part of the dermis,” noted Dr. Adam Geyer, Kiehl’s Consulting Dermatologist.
In studies, the biological impact of long UVA rays has been revealed to bring significant oxidative stress that can lead to inflammation, tissue, and cellular damage. Such photo-oxidative stress can manifest visible skin aging, such as wrinkles, altered pigmentation, and loss of skin tone .
“Photoaging caused by long wavelength UVA rays is complex as these harmful rays cause damage on a number of levels,” continued Dr. Geyer. “Their effects cause skin to quickly darken and appear dull. Long UVA rays also disrupt the skin’s immune function and damage the skin’s deeper vital structures, leading to skin that lacks firmness and elasticity, may appear more red and visibly wrinkled. Protection against harmful long UVA rays is particularly important.”
A TRIPLE DEFENSE AGAINST SUN DAMAGE
With an understanding of damage caused by long UVA rays, Kiehl’s chemists set out to enhance the protection of current broad-spectrum sunscreens with an advanced and unique combination of sun filters to defend the skin against the three forms of skin damaging UV rays that reach the earth’s surface.
“Kiehl’s Sun Filter System offers triple UV defense sun protection,” stated Dr. Geoff Genesky, Head of Kiehl’s Skincare Laboratory. “To achieve this, we formulated with a new and unique blend of Sunscreen Filters that includes Mexoryl SX™ and Mexoryl XL™ sun filters to protect against UVB, short UVA, and now enhances coverage in the long UVA range.”
The formula is fragrance-free, oil-free, non-comedogenic, and provides all day hydration. This enhanced UV protection also features tried and true anti-oxidant Vitamin E for its skin conditioning benefits and ability to help protect skin from free radical damage.
Used daily, this gentle, non-greasy and lightweight lotion leaves skin with a matte finish while providing reinforced prevention against signs of premature skin aging.
