Light Therapy for Acne and Wrinkles
Recommend Anti-Aging Skin Care
Blue Light Therapy for Acne
How it Works: Specific wavelengths of blue light target the strain of bacteria that plays a pivotal role in causing acne for many people. The light causes the development of oxygen radicals that kill P. acnes bacteria without damaging healthy skin.
- Why you should consider it: Demonstrated effective in destroying levels of acne-causing bacteria; best for mild to moderate inflammatory acne; there are handheld devices you can use at home; reduced potential for side effects (such as dryness or peeling) that can occur with benzoyl peroxide or topical prescription products; a worthwhile option for those whose skin cannot tolerate topical disinfectants; pain-free, no downtime; safe to have done when pregnant or breastfeeding.
- Why you shouldn't consider it: If done by a medical practitioner, requires several treatments per week; expensive (averaging $40 per treatment); LED treatments are not effective for cystic acne, blackheads, or whiteheads (milia); long-term results are unknown (but the treatment does have a good safety record).
Professional device names: ClearLight Acne Photoclearing System; Blu-U; Omnilux Blue.
Red Light Therapy for Wrinkles
How it Works: Wavelengths of red light that may help improve skin’s barrier function by improving its ability to retain key elements it needs to heal and generate new collagen after its production has slowed due to age or cumulative damage. Red light LEDs are also believed to target the skin’s oil glands to reduce cytokines, a class of pro-inflammatory substances believed to play a role in chronic acne.
- Why you should consider it: May help reduce signs of aging, including wrinkles around the eyes; a better choice for those struggling with acne and wrinkles; minimal risk of side effects, especially when used without light-activating chemicals (this is common when done by a medical professional); no downtime.
- Why you shouldn't consider it: Whether done by a medical professional or at home with a handheld device, requires multiple treatments; does not affect acne-causing bacteria; long-term results are unknown (but so far these treatments seem to be safe); when done by a medical professional, the costs can vary from $50–$200 or more per treatment, depending on the device and treatment protocol your dermatologist prefers.
Device names: Acnelamp (available as a handheld or tabletop option; prices vary); Omnilux Revive, Omnilux Red (in-office only).
If you are considering an at-home light-emitting device for anti-aging or clearing acne, we'd recommend shopping carefully and buying only from reputable manufacturers. Due to concerns over lawsuits, most manufacturers of these devices are forced to limit their intensity, often to a much lower strength than the LED-emitting machines your dermatologist uses. In a sense, that’s good news because it is possible to overdo these treatments and consumers could end up damaging their skin, which is never the goal.
Some LED devices sold to consumers actually do match the strength of those used in the dermatologist's office. This is definitely an issue where caution is warranted, so be sure to read all accompanying instructions and follow the usage directions to the letter!
At-home devices we recommend for treating acne: Quasar MD Blue ($595); Quasar Baby Blue ($349); Quasar Clear Rayz for Acne ($249); Tria Acne Clearing Blue Light ($299).
At-home devices we recommend for treating wrinkles: Quasar MD Plus ($795); Baby Quasar Plus ($399); Tanda Luxe Skin Rejuvenation Photofacial Device ($195).
LED light-emitting devices require protective eye wear. The wavelengths they emit can damage unprotected eyes, and if you don’t remember to protect your eyes at home with the higher intensity output you would be risking your sight. Be sure to invest in protective eyewear prior to using such devices around your eyes, and never look directly into the device.
Don't get to caught up in the "FDA approved" for what's known as "class 2 medical device" claim that's used for many at-home LED devices. All this means is that the FDA approved the device for safety, not effectiveness. Latex gloves are also a class 2 medical device, as are wheelchairs. This distinction is a key reason it’s important to look at the published research demonstrating results, not a blanket, potentially misleading claim of FDA approval.
TRIA Laser Hair Removal
Many (so many we lost count) of our readers have asked about TRIA laser hair removal. The TRIA is an 810-nanometer diode laser system with research showing it can reduce hair growth on the underarm, legs or elsewhere. It is tricky to use and the instructions must be followed exactly or the machine won't produce even minor results, but it is absolutely an option to consider if you are willing to make the time and financial commitment (and yes, it hurts). We do not recommend TRIA for any other purpose other than hair removal, and strongly advise you to follow the directions exactly, which includes not overdoing it (this isn’t a situation where more frequent treatments will produce better results).
The Bottom Line
As far as treating acne, in-office dermatologist administered LED treatments are worth considering if other topical medications haven’t worked, or before you see a dermatologist you can try one of the at-home LED devices for acne. Just keep in mind that skin-care products with benzoyl peroxide, salicylic acid, and tretinoin (a prescription-only topical medication), along with other medical options are the preferred first lines of defense.
For anti-aging, LED therapy is an option when performed in-office or with the right handheld devices for home use, but just like when used for treating acne, light therapy will never replace a great skin-care routine (and daily use of sunscreen, whether the forecast is cloudy or sunny)! At best, they are a complement, and at worst you won’t see results and will feel as though you’ve wasted your time and money.
Last, with any of these treatments, especially if you opt to use a device at home, consistency and patience are the keys to success. These treatments require a time commitment, and if you're not willing to invest the time, you may not want to invest the money—or you may want to see your dermatologist to discuss more "potent" treatments such as non-ablative lasers or fractional resurfacing.
