Benefits of Green Tea combined with LED light Therapy ______

Recently, scientists out of Germany, Andrei P. Sommer and Dan Zhu have documented the positive effects the topical application of green tea can have on the skin when used in conjunction with LED light therapy . 

In order to understand why green tea  is so powerful, it is first important to understand how LED can  impact the body. 

Clients, who have previously been exposed to free radical damage from environmental factors prior to starting a light based treatment, can have elevated levels of reactive oxygen species
(ROS) present in the body. 

An excess of ROS can significantly inhibit the cellular repair process and delay rejuvenation progression. 

LED, IPL, laser and other light based treatments help to significantly increase cellular growth and repair aged skin. 

On the
other hand, as light speeds up the cellular metabolism process and cellular activity, ROS and waste are also produced as a byproduct. 

In many cases, during LED treatments the body will create powerful internal antioxidants such as superoxide dismutase (SOD)
to alleviate any excess ROS and waste. However, if the ROS levels stay elevated and the body is unable to dispose of the excess, it can substantially delay the rejuvenation process.

Now that we have established that excess ROS can slow down the rejuvenation process, how do we prevent this from occurring? 

Sommer and Zhu have found that by utilizing the powerful ROS scavenger known as epigallocatechin gallate (EGCG) which is extracted from green tea we can lower the levels of ROS within the body. When EGCG  is applied daily in high concentrations, this antioxidant can reduce the presence of ROS and prolong the life of the cells responsible for transporting extracellular metabolic waste from the basal membrane to the top layer of the epidermis, resulting in accelerated
rejuvenation of the skin.

In order to ensure the fastest and best possible results from your light based treatments , use the ONYX XVII 
and Master Lift in combination with a skincare product including a high concentration of ECGC (Green Tea) 
This invaluable combo will help to ensure your clients’ ROS factor remains low and your results remain high.


Sommer AP, Zhu D. Green tea and red light--a powerful duo in skin rejuvenation. Photomed Laser Surg. 2009 Dec;27(6):969-71. doi: 10.1089/pho.2009.2547. PMID: 19817517.

Objective: Juvenile skin has been the subject of intense research efforts since ancient times. This article reports on synergistic complementarities in the biological actions of green tea and red light, which inspired the design of a green tea-assisted facial rejuvenation program.
Background data: The approach is based on previous laboratory experiments providing insight into a mechanism by which visible light interacts with cells and their microenvironment.
Methods: After 2 months of extreme oxidative stress, green tea-filled cotton pads were placed once per day for 20 minutes onto the skin before treatment with an array of light-emitting diodes (central wavelength 670 nm, dermal dose 4 J/cm2).

Results: Rejuvenated skin, reduced wrinkle levels, and juvenile complexion, previously realized in 10 months of light treatment alone were realized in 1 month.

Conclusion: The accelerated skin rejuvenation based on the interplay of the physicochemical and biological effects of light with the reactive oxygen species scavenging capacity of green tea extends the action spectrum of phototherapy. The duo opens the gate to a multitude of possible biomedical light applications and cosmetic formulas, including reversal of topical deterioration related to excess reactive oxygen species, such as graying of hair
