This invention describes a hand-held device for dermaplaning, which is a method of exfoliating skin. The device uses a blade assembly with a single blade held by a holder that has an enlarged nose at one end. While the full device is intended to vibrate the blade and include a safety cage to limit penetration for non-professional use, the provided claims specifically detail only this particular blade assembly.
Why it matters: Advancements in precision manufacturing techniques, such as micro-injection molding, have made it more cost-effective since 2020 to produce the intricate blade holder and safety cage designs required for safe, non-professional use.
