Everything you need to know in six minutes- from taking Lumohs Dermaplane out of the box, to adding #10 blade, inserting battery pack, turning on and off, and then cleaning. Simple to use and with just a slight twist of rear cap, light turns on and off, illuminating difficult to see areas on the skin. Direct light helps estheticians do Pre-Dermaplaning assessment, avoid danger zones on face, where you might cut the skin during dermaplaning. Keep much needed light directly on the skin while maintaining a relaxing spa ambience and experience without surgical lights.
