In the market, whether it's weight loss products or beauty products, they all claim to be "natural and harmless." Even laser beauty treatments claim to have no side effects. But let's think about it: lasers emit radiation. Could they really not cause harm to the body? Today, let's explore the risks of laser spot removal.
1. Eye Damage: Eyes are highly sensitive to intense light. Excessively strong light can cause temporary blindness. Lasers operate by emitting powerful light, and since laser beams are extremely bright and come in various colors—including green, yellow, red, and infrared light. These wavelengths 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 procedure.
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 high pain sensitivity may apply a topical anesthetic cream like 5% EMLA before treatment for better pain relief. For 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.
