Modern disposable razors feature colored strips near the blades that contain water-activated lubricants like polyethylene glycol. As you shave, water dissolves microscopic amounts of these polymers, creating a slippery layer between blade and skin. The strip also fades with use, serving as a visual indicator that the razor is losing effectiveness. This simple innovation reduced shaving irritation by over 25% when it was introduced in the 1980s.
