1. Potential Eye Damage: Eyes are highly sensitive to intense light, and excessive brightness can cause temporary blindness. Lasers operate by emitting powerful light, which comes in various wavelengths—including green, yellow, red, and infrared light. These wavelengths can cause significant damage to the retina and cornea. Therefore, specialized protective eyewear must be worn during operation. Patients should keep their eyes closed and wear protective goggles throughout the treatment.
2. Pain sensation: Laser treatment relies on high temperatures for efficacy. It's reasonable to expect discomfort at such intense levels. While some claim laser procedures are pain-free,but this is inaccurate. While it is true that laser treatments cause significantly less pain than other methods—with procedures like laser wrinkle removal and hair removal feeling akin to a rubber band snapping against the skin—patients with low pain tolerance may apply a topical anesthetic cream like 5% EMLA before treatment for better pain relief. For procedures such as laser spot removal and skin resurfacing, local anesthesia is also an option.
3. Post-Procedure Hyperpigmentation: Hyperpigmentation following laser treatments is a common concern. While its occurrence rate is low, once developed, it fades slowly—taking several months or even up to a year or two to resolve naturally.
4. Scarring: When laser therapy is used for spot removal, the risk of scarring is low provided the energy level is appropriately selected. During dermabrasion treatments, experienced practitioners can adjust the depth of abrasion based on skin color changes, preventing scar formation.
5. Skin Burns: Excessive laser energy during treatment can overwhelm the skin, causing redness, swelling, blisters, or even burns to the subcutaneous tissue beneath the epidermis, leading to irreversible damage.
