The effect of picosecond laser and how does the characteristic tattoo (TATTOO) stay on the skin?
Tattooing is to put a lot of ink and dyes under the surface of the skin. Since the body cannot absorb these pigments by itself, they will deposit and form a “collagen protective layer” on these positions and leave permanent patterns. Laser tattoo removal is actually the same as The method of laser speckle removal is the same, depending on the depth and color of the tattoo, laser equipment with different wavelengths will be used to remove it.
▎Preoperative instructions for picosecond laser
Patients with chronic diseases such as high blood pressure and diabetes should be controlled within the normal range. People with drug allergies or special constitutions should inform in advance.
Stop using topical A acid ointment one week before treatment, and do not perform fruit acid or other exfoliation, skin peeling and other treatments.
After 3 to 6 months, the oral administration of A acid is discontinued, and the period of withdrawal depends on the time and dose of oral administration.
1 month ago, please do not expose yourself to excessive sunlight, SPA or sunbathe.
If you have any of the following conditions, please inform in advance and consult a doctor to confirm whether treatment is possible. ◇After treatment, if there is an overseas trip or outdoor activities will be arranged. ◇Pregnancy, urticaria, viral infection at the treatment site, skin lesions, blood or immune system abnormalities. ◇Those who have had lip herpes before, because laser surgery may stimulate the recurrence of lip herpes. ◇If you have a serious illness, take special drugs, or have skin abnormalities in the near future.
▎The treatment process of picosecond laser
皮秒雷射的「皮秒」是一种时间单位,雷射击发时间由一般传统雷射的奈秒(nanosecond)缩短到皮秒(picosecond)单位,可在短脉衝时间内产生强大的光震波,减缓热效应与组织伤害,时间越短,热能越少,能量却增强,因此皮秒雷射具有超短脉衝时间的优势。

治疗时,不但能够有效率的破坏皮肤的色素与斑点,将色素击碎成细小的粉尘,更容易代谢,又不会过度产生热能,突破传统雷射容易造成的皮肤热伤害,以及可能产生反黑或是反白的现象,皮秒雷射的治疗恢复期相当短,有别于传统雷射需较长的恢复期与会有较大的副作用。
皮秒雷射的效果与特色
532nm的雷射波长针对浅层斑点治疗,像是蜡黄、红痘疤…等,1064nm则可改善更深层的黑色、咖啡色斑点,两台仪器皆有双波长的特性,让治疗的深度及范围更不受限制。
2.高瞬间能量:有效改善色素斑、缩减疗程次数。
- 短脉衝时间:去除小粒子色素、热伤害少、恢复期短。
▎皮秒雷射适合哪些状况使用?(适应症)
●刺青
●各式深浅斑(肝斑、雀斑、晒斑、老人斑、颧骨母斑、太田母斑)
●肤色不均
▎皮秒雷射皮秒雷射前先了解,为什麽脸上会长斑?
斑点形成的原因除了受个人体质影响外,肌肤若遭到阳光及紫外线的曝晒,就会使皮肤表皮基底层的色素母细胞分泌更多的麦拉宁黑色素,而这些黑色素如果不能正常顺利地代谢,就会导致斑点的形成。由于斑点的深浅、大小及型态皆不同,故雷射治疗次数及方式也依情况而有所不同。
▎痘疤跟斑点如何形成?
通常青春痘细菌感染程度越严重,疤痕的颜色越深,可藉由雷射方式帮助肌肤组织癒合、修复。
▎皮秒雷射的效果与特色刺青(TATTOO)是怎麽长留在皮肤上的?
刺青是将大量的墨水及染料置于皮肤的表层底下,由于身体无法自行吸收这些颜料,它们会沉积并于这些位置形成”胶原蛋白保护层”而留下永久的图案,雷射除刺青其实与雷射除斑的方法相同,会依刺青的深浅度和颜色,而使用不同波⻑的雷射仪器去除。
▎皮秒雷射的术前须知
- 慢性病如高血压、糖尿病患者请控制在正常范围内。有药物过敏或特殊体质的人应事先告知。
- 治疗前一週停用外用A酸药膏,另外请勿进行果酸或其他去角质、换肤等治疗。
- 3~6个月,停用口服A酸,停用期间依口服时间及剂量而定。
- 1个月前,请勿过度日晒、SPA或进行日光浴。
- 若有以下状况,请事先告知并徵询医师意见后确认是否可进行治疗。 ◇治疗后,若有安排出国行程或是将进行户外活动。 ◇怀孕、荨麻疹、治疗部位有病毒感染、皮肤病变、血液或免疫力系统异常者。 ◇曾经得过口唇型疱疹者,因为雷射手术有可能会刺激口唇型疱疹复发。 ◇如有重大疾病、服用特殊药物、近期内有皮肤异常。
▎皮秒雷射的治疗流程
- 术前谘询:医师按照个人需求评估治疗范围及建议施作次数
- 洗卸清洁、敷麻膏:美容师针对治疗范围仔细洗卸,并进行敷麻约20~30分钟
- 开始施打:施打前会戴上眼罩,保护眼睛
- 术后当下:脸上会有暂时性的泛红,这是正常现象,不用担心
- 镇定舒缓:适宜的冰敷及保湿缓解肌肤,疗程完成
