The Picks: Light Therapy
I recently attended a conference for spa professionals and one big trend I noticed was a ton of LED light therapy machines. The funny thing is, light therapy has been around for quite some time and is apparently making a come back and with good reason.
What does LED stand for + how does it work?
LED stands for light emitting diode. Basically, LED is a light source that emits infrared light and heat at different wavelengths that penetrate into skin cells. They were made famous by NASA for plant growth experiments. They have been studied a lot, they are not dangerous and they contain no harmful UV rays. They are actually safe for the eyes, though many units come with goggles for the sake of brightness.
For skin therapy, they are typically used via single light units, handheld wands or panels/masks that are pointed at the skin a few inches away. There are home and professional versions, and many different price points to fit everyone’s budget. I will note that the at-home versions are less potent than the pro versions but they are still very beneficial. The benefits are cumulative so it’s important to be consistent to reap all the benefits. I recommend around 5x a week.
What are the benefits of the different colors?
There are several colors of light therapy and often used in combination. All colors help with the penetration of skin care products for maximum results. These are the most popular & commonly used colors:
+ Blue kills P. acnes bacteria and minimizes redness. Studies indicate it reduces acne by 67% and blackheads by 50%! (It’s also used in teeth whitening!)
+ Red reduces inflammation which is great for acne, sensitive skin and rosacea. It stimulates collagen production so it’s great for fine lines and wrinkles. It’s also wonderful for wound healing and blood circulation.
+ Cyan (light blue) calms and soothes irritated skin and helps to reduce the size of capillaries.
+ Purple increases cell regeneration and renewal and it good for fine lines and wrinkles.
+ Green is wonderful for hyperpigmentation from sun damage or old post inflammatory pigmentation left from acne.
+ Orange is good for inflammation and reducing redness associated with rosacea and sunburn and promotes brighter skin.
There are so many options on the market and vary in price from $30 to thousands. These are my picks!
