Hot Topic in Dermatology … Introducing our new “superscreens”
Skin aging can be divided into two categories, intrinsic and extrinsic aging. Intrinsic aging is determined genetically and reflects the naturally occurring process that occurs with chronological age. There is not much that we can do as your cosmetic providers to combat this type of inevitable aging. Extrinsic aging on the other hand is the result of several interactions with environmental factors, most importantly being the SUN. “Photoaging” is a popular term that was coined in the 80’s to describe the negative effects that chronic UV exposure have on the skin. With UV exposure we see changes in the skin such as dry rough texture along with skin laxity, pigment changes, redness, visible blood vessels, deep creases and wrinkles.
Traditionally studies have shown the negative effects that UVA and UVB play in the role of aging skin as well as the potential for skin cancer. As sunscreens have evolved, we now notice that many will say broad spectrum meaning that they protect against UVA and UVB damage. What we have failed to consider until recently is the effects that other wavelengths of light can contribute. There is a growing body of knowledge that now recognizes the damaging effects caused by infrared (IR) and visible light. Solar IR is the actual heat that you feel from the sun. When skin temperatures are raised for a long period of time we see similar changes in the skin that are associated with photoaging. Therefore contributing to the ideas that thermal-aging or premature aging can be induced by heat causing destruction of collagen in elastin. So now that we have all this new information … what next?
A new category of sunprotection is now beginning to evolve … “superscreens”! Companies are now looking for a new approach to sunscreens with the most comprehensive protection and active ingredients.
