I found this: "
Q: Hi, I have severe keratosis pilaris all over my arms and legs, and a bit on my back. I have tried countless methods to diminish the gruesome bumps, to no avail. I've been wondering about laser hair removal coupled with microdermabrasion. Its seems to me that since this is a hair follicle disorder, getting rid of the hair and then smoothing out the skin would be the best solution. Besides it not being "in the dermatologist textbook" to try a method like this, I'm wondering if it would work. Many people out there are suffering from this, if a doctor were to research it...

A: Extensive keratosis pilaris is particularly refractory to therapy. Your laser hair removal theory makes great sense. Modern medicine does not, however, have a safe and effective way of destroying these villous hair follicles. Laser hair removal requires pigment to target the follicle. Villous hairs generally have little or no pigment so laser therapy cannot target them well. Microdermabrasion can be helpful, particularly when incorporated into a regimen containing medicated moisturizers I agree that a safe permanent remedy for this condition would be extremely valuable. Hopefully one day we'll have such a treatment.

and my comment would be ok but different lasers work on different basis and there are lasers that dont need the pigmentation, for instance from here:
"Photodynamic therapy may be a useful approach for hair removal. Because photosensitizers tend to localize in the follicular epithelium, photochemical destruction of all hair follicles, regardless of hair color or growth cycle, could potentially be obtained. The technique does not require a laser light source, making it potentially less costly than laser treatment. Long-term data and large-scale studies are needed to determine the safety and long-term efficacy of this modality. "

"Short contact photodynamic therapy is an exciting new treatment for acne, rosacea and sun damage. This combination treatment is also finding success in a variety of other conditions such as keratosis pilaris (severely dry skin), certain types of warts and excessive oiliness of the skin."

pubmed see conclusion. pulse dye laser and KP.

So it seems the pulse dye may be the way to go, yet the bumps remain... has anyone with bad KP had pulse dye and then tried any abrasive things like dermabration, salacylic wash etc without having a replapse?
