While both derma blades and regular razors have sharp blades, they are designed for different purposes and have distinct features that make them unique.
Derma blades are specifically designed for skin treatments and are typically made with a longer and sharper blade than regular razors. These blades are specifically crafted to make precise and shallow incisions in the skin, which can stimulate collagen production and promote skin rejuvenation.
Regular razors, on the other hand, are designed for shaving hair and are not suitable for skin treatments. The blades on regular razors are typically shorter and not as sharp as derma blades, which makes them unsuitable for skin treatments. Moreover, the risk of injury is higher with regular razors due to the design of the handle and the blade's angle of approach.
In summary, I strongly recommend that you use derma blades specifically designed for skin treatments and avoid using regular razors for any dermal procedures.
