Guides

What the evidence supports, what the marketing adds on top, and how to tell the two apart before you spend.

These are the pages I write when the same question keeps coming back and no review is the right place to answer it: what a wavelength actually does, why irradiance without a distance is a meaningless number, or how to read an FDA clearance instead of trusting a badge on a box.

I am not a dermatologist. On anything with a real safety stake, IPL eligibility first of all, I tell you what I do not know and I send you to someone qualified. A guide that pretends to certainty it does not have is worse than no guide.
