Liquid PCL: the ultimate injectable collagen biostimulator for face & neck – My proven approach & protocol for outstanding results with zero downtime
目标: Summarize why the neck ages early and visibly.
Explain how liquid PCL improves texture, elasticity, and fine lines via biostimulation.
Identify ideal candidates, including residual post-surgical laxity.
Apply the protocol (pretreatment, dilution, injection technique, session spacing).
Describe expected outcomes and key safety points for hypermobile areas (neck/perioral).
介绍: Liquid polycaprolactone (PCL) is a novel injectable designed to stimulate neocollagenesis, improve dermal density, and enhance skin tension with minimal discomfort and virtually no downtime—supporting gradual, natural-looking rejuvenation and offering an adjunct for residual laxity after surgery.
In this talk, I’ll present a series of cases in patients aged 40–77 treated with a pure 21% injectable liquid PCL formulation (without carboxymethylcellulose), with outcomes assessed after one and two sessions, focusing on texture, elasticity, and rhytide reduction.
材料 / 方法: Antihistamine and an antileukotriene prior to injection. For patient comfort, the product was prepared by mixing 0.2 mL of 2% lidocaine per 1.0 mL of liquid PCL. Facial treatment was delivered via a single entry point using a 27G, 50-mm cannula, with retrograde linear threading (0.3 mL per thread), performing two linear threads per side. Cervical treatment was administered using a skin pinch technique with a 32–34G, 4-mm needle, delivering 12 intradermal injection points of 0.1 mL each (total neck volume 1.2 mL per session).
结果: Across patients aged 40–77 years, results showed progressive clinical improvement. With significant enhancement in elasticity and reduction of fine rhytides. Csse photos will be shared on the day. No severe complications noted such as VO, Infections, granulomas or nodules. Only 1% experioenced severe facial swelling which resolved after 3-4 days without any consequences.
总结: Overall, this protocol was associated with improved cervical skin quality, including enhanced texture, increased elasticity/skin tension, & softening of fine rhytides, with minimal discomfort and little to no downtime. These findings support liquid PCL as a practical, non-surgical biostimulatory option for patients seeking gradual, natural-looking neck rejuvenation, & as a useful adjunct for persistent laxity following surgical procedures. Given its material properties & handling profile, liquid PCL may represent a particularly safe non–hyaluronic acid biostimulator for use in hypermobile area
