All you need to know about led light therapy: benefits, different types and safety.
Light therapy was originally developed for astronauts to help the healing process of tissue, but it has been used for the last 30 years for its benefits for treating acne, regulating oil production, improving the appearance of wrinkles, redness and stimulating the production of collagen and elastin.
The results are cumulative, this implies that if you can only go to the salon once a year, you won’t be seeing long-term benefits. Fortunately, many at-home devices have been developed for regular use.
Light therapy uses different types of light beyond the visible spectrum to penetrate different depths of the skin and is suitable for all skin types and tones.
Different types of light
- Red: soothes inflammation and redness, helps cellular repair and circulation.
- Blue: is used to kill bacteria, thus they are excellent to treat acne. Thanks to its antibacterial properties it helps purify the skin and regulate oil glands.
- Amber: revitalizes the skin, reduces swelling and increases radiance.
- Infrared: this type of light is invisible to the naked eye and penetrates deeper than any of the latter. Infrared light stimulates the natural production of collagen and elastin, replenishes dermal and epidermal cells and speeds up the recovery process.
Types of devices
There are several types of devices the most common being masks and wands. I would recommend getting a mask because you normally need to apply the light for 20 or 30 minutes, and holding a wand for that long can result in an aching arm.
No adverse effects have been associated with light therapy, but you have to make sure you close your eyes while wearing the light and consult a professional before getting one!
