Which process is defined as smoothing out irregularities of the skin?

The process described as smoothing out irregularities of the skin is dermabrasion. This technique involves the mechanical exfoliation of the outer layers of skin through the use of a rotating instrument, which effectively removes the damaged skin and promotes smoother, healthier skin to emerge underneath. Dermabrasion is particularly effective for treating deeper skin issues, such as scars, uneven texture, and fine lines, making it valuable for patients seeking significant skin rejuvenation.

Microdermabrasion, while also an exfoliation technique, operates on a more superficial level and is best for treating minor skin issues and surface irregularities. Chemical peels utilize acids to remove the outer layers of skin, which can lead to smoother skin but do not involve physical abrasion. Lastly, laser resurfacing uses lasers to target specific layers of skin for treatment but works under a different mechanism compared to the physical abrasiveness of dermabrasion. Each of these methods has its unique applications, but for directly smoothing out deeper irregularities, dermabrasion is the most fitting choice.
