True or False: Heat, not just ultraviolet, light damages the skin?
True! Did you know that emerging data shows that everyday low grade heat can cause accelerated aging of the skin including surface wrinkles, enlarged pores and brown spots ? What we traditionally call “sun spots” may not be entirely from sunshine but from heat exposure. Indeed, these findings are more common in kitchen workers, firefighters and even hot yoga aficionados...
For years, it has been universally accepted that ultraviolet light (from natural sunshine or tanning beds) damages DNA and generates free radicals that is harmful to the skin and leads to wrinkles, brown spots, broken capillaries, loss of skin tone. Only recently have we become aware that infrared light (i.e. heat) can cause similar damage. This is likely why really good sunscreen – certainly a critical component of any skin care regimen – does not fully protect against all of your cosmetic concerns.
Traditional sunscreens are ONLY designed to filter out damaging UV light but do nothing when it comes to infrared light protection. Nothing.
Scientists have wondered for years how certain species of bacteria can survive (and even thrive) in environments that you’d think to be hostile to life. These are memorably referred to as extremophiles. Thermus Thermophilus is one such beast. It is an incredibly resilient bacterium which lives around the incredibly hot thermal vents at the bottom of the ocean floor. It makes a series of natural proteins that consistently repair the cellular damage which occurs as a result of unending high temperature.
You might wonder “How on earth can an ocean floor bacterium help my skin” ? Quite simply, actually. Scientists at Sedamed Laboratories in France have developed a stable extract from Thermus Thermophilus (known as Venuceane TM) which has been found to prevent harmful effects from heat on your cells. It prevents cell membrane damage, oxidative stress and DNA damage. In practical terms, it means that there is now protection from everyday low grade thermal injury to your skin.
Revoderm has now added Venuceane TM to our everyday zinc sunscreen (Age Defy). We anticipate that you will find this thin, micronized sunscreen indispensable for your daily environmental defense. It has beautiful, thin cosmesis and is easily colour matched for you. This has already become a very “hot” (no pun intended) item and we suspect that you will love it.
Here’s to healthy, beautiful skin!
