| Plcoskin is a MedTech company specializing in reconstructive plastic surgery and regenerative skincare. They have developed a scaffold that removes the need for cadaver-sourced material used in breast reconstruction surgery, making procedures safer and cheaper. Plcoskin’s scaffolds are made with synthetic PCL, a biodegradable material that iscommonly used to create surgical sutures. Unlike competitors' products that remain in the body for a lifetime, Plcoskin’s PCL scaffolds are absorbed and replaced with the recipient’s own natural tissues, minimizing the possibility of long-term side effects. As they do not contain any dangerous chemicals, they are also 50% safer than cadaver-sourced scaffolds.Costs for reconstructive breast surgery are brought down by 40% to only $3 thousand per breast. Furthermore, much less handling time is required, reducing average surgery durations from an hour and a half to only 30 minutes. The mesh design of the scaffolds mitigates the need for an additional follow-up reconstructive surgery, something that is common when using cadaver-sourced scaffolds.Plcoskin has also developed Youlief, a cosmeceutical product & therapeutic device pipeline that helps fund R&D for their medical devices. Youlief is available in the US, Europe, Taiwan, Singapore and Japan. | $10.1M / Series C / Oct 27, 2025 | ||
