Why are DNA repair enzymes deemed 'fundamental'?
To understand how DNA repair enzymes benefit our skin, we must first have a basic understanding of skin anatomy and what causes the visible signs of aging.
Every day, our skin is exposed to what is known asfree radicals (also referred to as ROS or reactive oxygen species). Free radicals are generated by environmental stressors such as UV, pollution, smoking, white cell activation and cell metabolism.
When activated, free radicals cause damage to DNA, resulting in dull and dry skin, loss of elasticity, wrinkles, and age spots.
Whilst broad-spectrum SPF and antioxidants (such as resveratrol, vitamin C, niacinamide) are great for scavenging free radicals and preventing damage, they cannot repair the damage to DNA that has already occurred, and that's where DNA repair enzymes come in.
How do they repair damage?
In a nutshell, DNA repair enzymes find damaged DNA, cut it out and then patch it with undamaged DNA.
Do they really work?
Although DNA repair enzymes are still relatively new within the mainstream skincare and beauty space, the surprising finding that bacterial DNA repair enzymes can indeed function inside human cells was first demonstrated nearly 45 years ago.
Then in 2015 the Nobel Prize in Chemistry was awarded to three scientists for mechanistic studies of DNA repair, culminating many decades of research showing DNA is able to repair itself.
Where can you find these skin-loving, must-have ingredients?
We have harnessed the power of 3 DNA repair enzymes in our Complete Daily Armour, Complete Night Shield and Lip Shield and Repair.
