Hi guys!
Like Cindy said a few posts ago, I've only recently started laser and although I can't remember the model that they use its big and grey/white and looks like a washing machine. Does that help?
HAhahaha, Joking! I'll ask what model it is next time I'm in.
Cindy is right on the money with the timing of hair growth, thats why it (unfortunately) takes so long and why people on electro need so many appointments, you need to catch every hair follicle at a particular growth phase in order for the treatment to be effective.
I've gone through the safety and potential scarring topics with my nurse/laser tech (who has been doing it for a long time) and one of the biggest risks (other than scarring and burns) is of hyperpigmentation from a combination of things. So basically, using too high a setting, frequently hitting the same spot, sun exposure (I always wear sunscreen whenever I walk outside now), all sorts of things that pretty much mean you need to know what you are doing, otherwise you can end up with blotchy patches all over your face. Permanently. Does not appeal to me!
Scarring <shudder> is the one thing that scares the hell out of me with it all. When we consider that its a "freakin' laser beam" that we are pointing at ourselves I really wouldn't trust myself with it, let alone someone that hasn't been trained or has much experience.
I can totally relate to the money thing, I am currently experiencing some "fiscal difficulties" and I think that in order to get a good result we need to fork out for it. You get what you pay for. This is our body we are playing with and in the same way that I could never consider shonky hormones or anything bought over the net (I mean really, it could be rat poison for all we know) and I truly believe that we need to take care of ourselves.
We need to budget for these things and for me $100 a month is chicken feed for the end result of having little to no facial hair. That works out to be about a coffee a day. I like coffee, I would love a coffee a day but I'd LOVE to have a clean hairless face!
Not trying to scare the crap out of anyone and going a bit medical/nursing on you, laser is super heating the hair follicle at a particular stage of hair growth in order to literally burn it to death. Consider the amount of energy required to do that and then think how risky that could be. I trust medical practitioners and people specifically trained to do such a job, particularly those who have years of experience (not to mention good recommendations) to do such things but I wouldn't trust myself.
In closing this rant, and apologies, it is a rant, I wouldn't recommend it. Next time I'm in I'll ask my nurse about the tria and other home setups and get back to you all. Not for a few weeks though

Hope I have been useful!
