Trypsin is a proteolytic enzyme that has been utilized in wound care and the treatment of certain skin infections due to its ability to break down proteins, thereby aiding in the removal of necrotic tissue (debridement). This enzymatic debridement facilitates wound healing and can reduce bacterial load by removing dead tissue that harbors pathogens. There is some scientific evidence supporting the use of topical trypsin, often in combination with other enzymes such as chymotrypsin or in preparations like trypsin-balsam-peru-castor oil, for the management of chronic ulcers, burns, and infected wounds.

Several clinical studies and reviews have examined the efficacy of trypsin-containing preparations. These studies generally indicate that enzymatic debridement with trypsin can be as effective as mechanical or surgical debridement, especially in patients who are poor candidates for surgery. However, the evidence base is limited by small sample sizes, variable study quality, and heterogeneity in wound types and outcomes measured. While trypsin may help accelerate wound cleaning and promote healing, it does not directly treat skin infections but rather creates an environment less conducive to infection by aiding tissue repair and cleanliness. It is not considered a first-line treatment for infections but can be a useful adjunct in comprehensive wound care.

In summary, there is modest scientific support for the use of topical trypsin in wound care, particularly for enzymatic debridement, but more robust clinical trials are needed to clearly establish its efficacy specifically for treating skin infections.
