Laser facial treatments use precise beams of light to improve skin's appearance by targeting concerns like wrinkles, acne scars, sun damage, and uneven tone. These procedures work by either removing damaged outer layers of skin or stimulating the production of new collagen and elastin in deeper layers, leading to a smoother, firmer complexion over time. The specific type of laser, such as ablative (for more dramatic results with more downtime) or non-ablative (for gradual improvement with less downtime), is chosen based on the desired outcome.
