Ok, here's the wolfkeeper blue/red light cheatsheet:
Research:
- yeah, it really works, it's *not* quackery.
- the research says it works for about 2/3 of people
- 3 months gives about 75% clearance (compared to about 40-50% clearance in studies with BP)
- clearance lasts for up to 6 months!
- no evidence that it causes cancer (unlike UV treatments), it seems reasonably safe at this point (compared to going out in the sun- don't worry- compared to accutane- really don't worry!). There is some suggestion that visible blue light has a slight aging effect. If so, it's *much* slower than UV. I haven't noticed this at all. On the contrary, my skin looks much, much better without the acne. I literally look younger. If you stay out of the sun otherwise, or use suntan lotion- you'll age slower than everyone around you. Don't sweat this.
- it's not necessarily suitable for asian or mexican people with a slight in-built tan- it will work but it has been reported that it tends to darken that kind of skin very slightly.
- blue light kills 99.9% of P.Acnes after 3 days of application.
- works for mild-moderate acne
- don't let the light go in your eyes (blue light has been associated with a form of blindness- retinal myopathy- that old people get). It's critical to use the goggles.
Practical Experience:
- don't be scared- it's not a rip-off!
- it mostly prevents new spots. Spots won't heal much faster, but the red light may help slightly.
- the manufacturers recommend 15 minutes- I say 10 minutes, once a day. 15 minutes seems too long for me; YMMV though.
- don't expect much improvement in the first 6 weeks- do NOT under any circumstances give up before 8-12 weeks! I repeat do NOT give up. IMO quite a lot those 1/3 people that it didn't work for- they gave up too early.
- use it EVERY day
- the home use treatments work just as well, possibly better, than the dermo office treatments, and quite a bit cheaper- and if it doesn't work for you- you can *sell* the equipment to someone else and get most of your money back, or the manufacturers will often allow you to return it- on the other hand, if the dermo appointments don't work- tough! The home-use equipment doesn't wear out very quickly; second-hand is fine unless it's years old.
- you have to use it EVERYDAY for atleast 8 weeks to get any big improvement (skipping maybe one day a week you can get away with, but try not to.)
- blue/red light has the best history for lack of side-effects of any acne treatment. Some people get very slightly drier skin, but mostly in a good way. Moisturise it if needed and cut back till it clears up. The red light gives a temporary face lift effect if anything.
- blue/red light is easy to apply, and you don't need to wash it off. Even washing skin can cause acne...
- don't wear suntan lotion or coverup makeup whilst applying the light, it will only reflect it away.
- apply the light from different angles in each session to get good evenness
- apply the light to your fingertips too (it helps sterilise them, otherwise you self-infect)
- try not to touch your skin between sessions
Advantages:
- it seems slightly better than benzoyl peroxide
- it doesn't bleach clothing/hair
- it's relaxing to apply
- you don't need to wash area/hands to apply it multiple times per day
- only need to apply it once a day
- whilst treating area, you don't need extra moisturising
- for a few days after treatment, skin just looks better in general (the red light makes the skin grow better- it's the only obvious and nice side effect)
- no significant negative side effects
- unlike antibiotics, it seems unlikely that resistance will develop
- it doesn't overdry the skin
- if used on the underarm region it kills the relevant bacteria and makes the pits less smelly!
Disadvantages:
- it can be a bit boring
- the research says it's only slightly better than benzoyl peroxide
- light box/equipment is a bit bulky to carry around
