I bought a Philips Lumea during Covid. Still hair free. It took a long time. Both in how long each session took and for it to stop my hair from growing. I have a few stragglers on my pits. Most likely because it’s a difficult location to diy. Expensive, yes. But I can now spot zap places with re-growth if I ever need to. Works best on light skin with dark hair. I greyed early, and I have a few strands of grey on my leg that didn’t get zapped.
