Dermaplaning and shaving are two very different services. Both services will remove vellus hair on the face, but only one will remove the dead skin cells.
The blade that is used for shaving is a flexible blade designed to glide over the skin, and will remove only hair.
A dermaplaning blade is a rigid blade designed to exfoliate several weeks of dead surface cells from the face. Once the dead skin cells and vellus hair is removed, your skin care products are able to penetration deeper, boosting the effects of products while making the skin look and feel smoother. Dermaplaning is also beneficial for reducing the appearance of acne scars.
