CoffeeBerry Extract, found in Revaleskin products, currently has the highest antioxidant potential of any ingredient. This assessment is based on the Oxygen Radical Absorbance Capacity Score (ORAC) — a method developed by the U.S. Department of Agriculture as the standard to measure the antioxidant capacity of natural substances. In plain terms, this means CoffeeBerry is a better antioxidant than green tea, white tea, vitamin C, vitamin E, grape seed extract or idebenone (Dermatologic Therapy, 2007). In fact, CoffeeBerry Extract has ten times the antioxidant power of green tea!
I’m a new fan of your blog! I came across it in my searches for reviews and insight on coffee berry.
So isn’t CoffeeBerry alone enough?
No studies to date have compared the effect of CoffeeBerry alone to combinations of other antioxidants, which may act synergistically to sustain their levels in the skin. In addition, different antioxidants work via different pathways and have varied sources. For instance, glutathione is naturally produced in the body and works in nearly all of the cells of the body, whereas vitamin C is obtained only from the diet and is important in producing collagen.
Can You Get Too Many Antioxidants in Your Skin Care?
Some people have been concerned about the possibility of using too many antioxidants, particularly from food, as reported in The Daily Mail. However, this is not as much a valid concern for skin care, for several reasons. First of all, the skin is continuously bombarded with UV light from numerous sources, including low levels from fluorescent light (GE, 2012). It is unlikely that you would be able to introduce so many antioxidants into your skin that it becomes dangerously anti-oxidant. Second, while the verdict is out on whether free radicals cause aging or are merely a side product of natural degenerative aging processes, it is known that free radicals accumulate with time. The older you are, the more likely you are to use antioxidant-rich topical products, the more free radicals that are likely there to be treating.
The one concern with antioxidants that needs to be addressed in the dermatological community is that of hormesis: It is known antioxidants can lead to a decrease of normal biological response to free radicals. This, in turn, could lead your skin to be more sensitive to oxidation for a period of time when you stop using antioxidant treatments. Still, with over 80% of the visible signs of aging attributable to UV light, and certain antioxidants proven to boost the power of sunscreen up to 4 times (Acto dermato-venearologica, 1996), would you really ever want to stop using antioxidants?
With that said, I use a combination of vitamin C and E in the morning, which are antioxidants long proven to increase the potency of UVA/UVB sunscreens (Acto dermato-venearologica, 1996). Following up with another potent antioxidant within a sunscreen, like CoffeeBerry in Revale Skin SPF 15 ($110.00, Amazon.com) or the green tea concentrate EGCG in Topix Replenix CF Anti-Aging Photocomplex SPF 45 ($28.00, Amazon.com) are excellent options.
At night, I use a retinoid followed by a treatment with antioxidants, like NEOVA Night Therapy ($68.99, Amazon.com). Again, I never worry about overloading my skin with too many antioxidants – in my opinion, it’s not much of a concern to begin with, and not really a concern at all if you continue to use antioxidants perpetually.
