Resurfacing the skin with deep chemical peels, dermabrasion, or lasers tightens the skin via dermal remodeling. The erbium (Er):YAG laser is a new laser for resurfacing and it removes lesional tissue efficiently with minimal residual thermal damage. In this paper, I present the first published study, to my knowledge, documenting and quantifying the cutaneous contraction following Er:YAG laser resurfacing of human skin.
To document and measure the cutaneous contraction resulting from Er:YAG laser resurfacing.
Using lentigos as skin markers, square areas on human forearm skin were resurfaced with the Er:YAG laser. The distance between these skin markers was measured before, immediately after, at 3 days, and weekly for 16 weeks after laser surgery.
After two to three passes with the Er:YAG laser, there was an immediate 4% linear tightening of the skin, which persisted at 3 days, increased to 8% at 1 weeks, was 11% at 2 and 4 weeks, 13% at 6 weeks, and 14% at 16 weeks.
Er:YAG laser resurfacing produces measurable cutaneous contraction. This phenomenon may contribute to the positive clinical tightening of human skin following Er:YAG laser resurfacing.
使用深层化学剥脱、磨皮术或激光对皮肤进行表面重塑可通过真皮重塑使皮肤紧致。铒（Er）：钇铝石榴石激光是一种用于皮肤表面重塑的新型激光，它能有效去除病变组织，同时使残留热损伤最小化。据我所知，本文首次发表了一项研究，记录并量化了Er：YAG激光对人体皮肤进行表面重塑后的皮肤收缩情况。
记录并测量Er：YAG激光表面重塑引起的皮肤收缩。
以前臂皮肤上的雀斑作为皮肤标记，使用Er：YAG激光对前臂皮肤的方形区域进行表面重塑。在激光手术前、术后即刻、术后3天以及术后16周内每周测量这些皮肤标记之间的距离。
使用Er：YAG激光照射两到三次后，皮肤立即出现4%的线性紧致，这种紧致在术后3天持续存在，在术后1周增加到8%，在术后2周和4周为11%，在术后6周为13%，在术后16周为14%。
Er：YAG激光表面重塑会产生可测量的皮肤收缩。这一现象可能有助于解释Er：YAG激光表面重塑后人体皮肤临床上出现的正向紧致效果。
