Women universally desire fair skin. When facial blemishes persist, laser treatments become essential for achieving a smooth complexion. Lasers do not forcibly remove pigmentation but work through the skin. However, improper post-treatment care may lead to scarring. Crucially, lasers are selective—targeting pigment particles while sparing healthy skin.
Laser therapy works by directing laser energy through the skin to target pigmented lesions. Under intense laser exposure, freckle pigments undergo structural changes and gradually dissipate, achieving resolution.
Tattoos and permanent makeup: These involve artificially implanting pigment into the dermis or accidental injury causing foreign objects like pencil lead or iron filings to enter the skin. All these types of pigmented lesions can be removed with laser treatment, with the number of sessions required depending on the pigment's depth.For example, Nevus of Ota, residing in the dermis and causing widespread facial darkening, may require one to two years of treatment. Due to the pigment's depth and the laser's limited energy penetration, surface pigments absorb the laser first. After approximately three months, when surface pigmentation lightens, subsequent laser sessions are performed until complete improvement is achieved. This treatment demands patience and is relatively complex and costly.While most cases can be cured, the duration varies. Compared to Nevus of Ota, shallower café-au-lait spots or freckles typically resolve with a single laser session. Non-melanocytic tattoos and eyebrow tattoos also fall under pigment issues; those within the black or blue spectrum can be cleared by laser. However, red and yellow pigment problems currently have no effective solution.
Laser Pigmentation Removal Reminder: Summer is not an ideal time for laser pigmentation removal. Many women utilize laser treatments to remove facial pigmentation and moles. Pigmentation is formed, and patients are required to apply sunscreen for life after the procedure. However, due to the intense sunlight and strong ultraviolet radiation in summer, laser pigmentation removal surgery is generally not recommended during this season.
Even with sunscreen, laser treatments expose skin to UV radiation, and sunscreen cannot block 100% of UV rays. Since pigmentation formation is linked to sun exposure, undergoing laser treatment during this season increases the risk of recurrence.
Post-laser care guidelines include avoiding water contact with the treated area for 4-7 days. Apply ice packs if swelling or discomfort occurs. After 6 days, gentle cleansing is permitted, but take care not to dislodge scabs. Itching may occur during healing—resist the urge to scratch.Avoid unnecessary sun exposure for 3 to 6 months post-treatment. Refrain from using other medications or cosmetics, especially makeup, until scabs have fallen off to prevent inflammation or impaired healing. Once the area is fully healed (approximately 6 to 10 days), cosmetics may be used as usual. Generally, it is advisable to avoid travel after laser procedures.UV radiation harms skin by causing sunburn, premature aging, spots, wrinkles, photodermatitis, and skin cancer. Therefore, beyond covering exposed areas like the face, lips, ears, hands, and feet with clothing, remember to wear UV-protective sunglasses for comprehensive sun protection year-round.
