The market for products and techniques that correct the visible signs of facial ageing is now huge. There is a diversity of devices and treatments now vying for a share of this growing marketplace, including polymer implants and injectable preparations that are based on an array of substances. The vast majority of these devices can only provide temporary correction of superficial lines and wrinkles, with volumetric augmentation being beyond their capabilities. The products and procedures suitable for the restoration of facial volume are discussed here.
The restoration of facial volume has long been neglected in cosmetic rejuvenation as surgical procedures increase skin tension but do nothing to restore the underlying facial volume, which is a subtle yet important characteristic of the youthful face. Fortunately, devices are now available which can augment facial volume for long periods of time or even permanently. These include implants based on expanded polytetrafluoroethylene and silicone rubber, which provide permanent restoration of volume, but require invasive surgery and do not age with the surrounding tissues eventually resulting in an unnatural appearance. The cosmetic rejuvenation market now abounds with various injectable devices, including: poly-L-lactic acid (PLLA), polymethylmethacrylate, collagens, hyaluronic acids, silicone and calcium hydroxylapatite. The choice of which one to use in practice is physician led, based on facial assessments, product characteristics and the desires of the patient.
Although there is a wealth of products available, injectable PLLA (Sculptra) can restore volume to the face providing a natural look. Not only are the results of volume augmentation using this device long lasting, but they are also safe.
如今,用于改善面部衰老可见迹象的产品和技术市场规模巨大。现在有各种各样的设备和治疗方法在争夺这个不断增长的市场份额,包括基于一系列物质的聚合物植入物和注射制剂。这些设备绝大多数只能暂时改善浅表皱纹,无法实现面部容积的增加。本文将讨论适合恢复面部容积的产品和方法。
在美容年轻化过程中,面部容积的恢复长期以来一直被忽视,因为外科手术会增加皮肤张力,但对恢复面部深层容积毫无作用,而面部深层容积是年轻面容的一个微妙却重要的特征。幸运的是,现在有一些设备可以长时间甚至永久性地增加面部容积。这些包括基于膨体聚四氟乙烯和硅橡胶的植入物,它们能永久性地恢复面部容积,但需要进行侵入性手术,且不会随周围组织一起老化,最终会导致外观不自然。美容年轻化市场现在充斥着各种注射设备,包括:聚左旋乳酸(PLLA)、聚甲基丙烯酸甲酯、胶原蛋白、透明质酸、硅酮和羟基磷灰石钙。在实际应用中选择使用哪种产品,由医生根据面部评估、产品特性和患者需求来决定。
尽管有大量产品可供选择,但注射用PLLA(塑然雅)可以恢复面部容积,呈现自然外观。使用该设备增加面部容积的效果不仅持久,而且安全。
