Glossary
A comprehensive look at bovine colostrum used in skincare, covering the growth factors (IGF-1, TGF-beta, EGF), immunoglobulins, and lactoferrin that give colostrum its documented regenerative, anti-aging, and wound-healing properties.
Bovine colostrum contains over 90 bioactive compounds including growth factors that stimulate cell proliferation (IGF-1, TGF-beta), epidermal growth factor (EGF) that promotes skin cell renewal, lactoferrin (antimicrobial and anti-inflammatory), and immunoglobulins that support skin immune function.
Multiple studies have shown these growth factors remain biologically active when applied topically, meaning they can interact with skin cells and stimulate repair processes. A 2020 study in the Journal of Cosmetic Dermatology found that colostrum-based cream improved skin elasticity and reduced wrinkle depth over 8 weeks.
Colostrum appears in skincare as freeze-dried powder, liquid extract, or incorporated into creams and serums. It is typically used at 1-10 percent concentration in formulations targeting aging, wound healing, and skin barrier repair.
The combination of growth factors and antimicrobial compounds makes colostrum particularly interesting for compromised skin: post-procedure recovery, chronic wound support, and barrier-damaged skin all benefit from colostrum's multi-mechanism regenerative activity.
No. Colostrum is the first milk produced by mammals after giving birth. Most skincare colostrum comes from bovine (cow) sources. It is not suitable for vegan skincare routines. Plant-based growth factor alternatives include bakuchiol and certain peptides.
Clinical studies support colostrum's skin regeneration effects. The growth factors (IGF-1, EGF, TGF-beta) have well-documented roles in cell proliferation and tissue repair. While more research is needed, the existing evidence is promising for anti-aging and wound healing applications.
Topical colostrum products do not cause lactose intolerance symptoms because the colostrum is applied to skin, not ingested. However, individuals with true dairy protein allergy (not lactose intolerance) should patch test colostrum products due to potential allergic reactions.
