Nonablative lasers and nonlaser systems are newer systems used for skin rejuvenation, tightening, body sculpting, and scar remodeling.
Different technologies such as lasers, Intense Pulsed Light (IPL), and radiofrequency have been introduced. Most nonablative laser systems emit light within the infrared portion of the electromagnetic spectrum (1000-1500 nm). At these wavelengths, absorption by superficial water containing tissue is relatively weak, thereby effecting deeper tissue penetration. A detailed understanding of the device being used is recommended.
Nonablative technology have been used for several indications such as skin tightening, periorbital tissue tightening, treatment of nasolabial lines and jowl, body sculpting/remodeling, cellulite reduction, scar revision and remodeling and for the treatment of photodamaged skin.
Nonablative laser and light modalities can be carried out in a physician treatment room or hospital setting or a nursing home with a small operation theater.
The dermatologic consultation should include detailed assessment of the patient's skin condition and skin type. An informed consent is mandatory to protect the rights of the patient as well as the practitioner. All patients must have carefully taken preoperative and postoperative pictures.
Depends on the indication, the area to be treated, the acceptable downtime for the desired correction, and to an extent the skin color.
These lasers are mostly pain-free and tolerated well by patients but may require topical anesthesia. In most cases, topical cooling and numbing using icepacks is sufficient, even in an apprehensive patient.
The nonablative lasers, light sources and radiofrequency systems are safe, even in darker skin types, and postoperative care is minimal. Proper postoperative care is important in avoiding complications. Post-treatment edema and redness settle in a few hours to a few days. Postoperative sun avoidance and use of sunscreen is mandatory.
非剥脱性激光和非激光系统是用于皮肤年轻化、紧致、塑形和疤痕重塑的较新技术。
已经引入了不同的技术,如激光、强脉冲光(IPL)和射频。大多数非剥脱性激光系统发射电磁光谱中红外部分的光(1000-1500nm)。在这些波长下,含有组织的浅层水的吸收相对较弱,从而实现更深的组织穿透。建议对正在使用的设备有详细的了解。
非剥脱性技术已用于多种适应证,如皮肤紧致、眶周组织紧致、治疗鼻唇沟和下颌、身体塑形/重塑、减少脂肪团、疤痕修复和重塑以及治疗光损伤皮肤。
非剥脱性激光和光模式可以在医生治疗室或医院环境中进行,也可以在带有小型手术室的疗养院中进行。
皮肤科咨询应包括对患者皮肤状况和皮肤类型的详细评估。强制性的知情同意是保护患者和医生权利的必要条件。所有患者都必须仔细拍摄术前和术后照片。
取决于适应证、要治疗的区域、所需矫正的可接受停机时间,以及在一定程度上取决于肤色。
这些激光大多无痛,患者耐受性良好,但可能需要局部麻醉。在大多数情况下,使用冰袋进行局部冷却和麻木就足够了,即使是在紧张的患者中也是如此。
非剥脱性激光、光源和射频系统是安全的,即使在较深肤色的人群中也是如此,术后护理很少。适当的术后护理对于避免并发症很重要。治疗后水肿和红肿会在数小时到数天内消退。术后避免阳光直射和使用防晒霜是强制性的。
