Polycaprolactone

Polycaprolactone is a synthetic polymer—a long-chain molecule made from repeating units of caprolactone. It belongs to a class of materials called polyesters and is used in skincare primarily as a stabilising agent in injectable formulations rather than as a topical ingredient.In cosmetic applications, polycaprolactone functions to maintain the structural integrity and consistency of injectable products, helping them remain stable over time and deliver other active ingredients effectively to deeper skin layers.

Polycaprolactone works by forming a stable matrix within injectable formulations. Its polymer structure allows it to encapsulate or support other active ingredients, preventing degradation and ensuring consistent delivery when injected into the skin.The ingredient's biocompatibility means it can be used in products designed to stimulate the skin's natural regenerative response, though the mechanism depends partly on what other ingredients are present in the formulation.

Polycaprolactone is not typically found in traditional topical skincare products; it is primarily used in professional injectable treatments administered by qualified practitioners. If you are considering injectable skin rejuvenation treatments containing this ingredient, ensure they are performed by a trained dermatologist or aesthetic practitioner who can assess your individual needs and skin condition.

Polycaprolactone is generally considered biocompatible and well-tolerated in injectable formulations. As with any injectable treatment, there is a potential for localised reactions at the injection site; consultation with a healthcare professional is recommended before treatment.
