Science
Mechanism of Action
Nonfat Dry Colostrum's efficacy is rooted in its diverse array of bioactive components, including vital growth factors (such as IGF-1, TGF-β, EGF, and PDGF), immunoglobulins, lactoferrin, cytokines, hyaluronic acid, vitamins, and minerals. These elements collectively drive multiple pathways: growth factors stimulate keratinocyte proliferation and migration, crucial for tissue repair, increased skin thickness, improved collagen matrix formation, and enhanced fibroblast activity, thereby promoting anti-aging and healthy skin growth. Lactoferrin imparts anti-inflammatory, antimicrobial, and antioxidant protection, reducing inflammation and aiding in the combat against acne-causing bacteria. Immunoglobulins bolster skin immunity, while hyaluronic acid ensures optimal hydration. Antioxidants neutralize free radicals, mitigating premature aging. Additionally, colostrum reinforces the skin barrier, diminishing redness and calming skin irritation.
Research
Clinical Evidence
Medium confidence15%
Key findings
- 01 A cream containing 15% sheep colostrum, applied for eight weeks, significantly improved skin moisture, reduced transepidermal water loss (TEWL), enhanced skin firmness and softness, and decreased redness and hypersensitivity in 25 mature women aged 40-70. No adverse dermatological effects were noted.
- 02 In vitro studies on human keratinocyte (HaCaT) cell lines demonstrated that 5% and 10% bovine colostrum promoted superior cell growth, exhibiting a mitogenic and proliferation-supporting effect. It also facilitated the migration of human keratinocytes and re-epithelialization at wound sites.
- 03 A 20% horse colostrum emulsion, applied twice daily for 30 days in seven patients with moderate atopic dermatitis, showed greater softening, moisturizing, soothing, and anti-inflammatory benefits compared to commonly available emulsions, leading to reduced erythema and pruritus without observed side effects.

Dusting Analysis
Clinical and in-vitro studies demonstrate significant efficacy at concentrations ranging from 5% for cellular benefits to 15-20% for comprehensive topical improvements. Therefore, Nonfat Dry Colostrum is unlikely to be 'dusted' when formulated within these effective percentage ranges.
The Formula
Formulation
Stability
The bioactive compounds in colostrum are highly sensitive to heat and light. To preserve its integrity and efficacy, gentle processing methods such as low-temperature concentration and lyophilization (freeze-drying) are essential. High-temperature processing can denature proteins and degrade heat-sensitive components. Formulations are optimally stable within a pH range of 4.7–5.2 and should be stored in opaque containers at cool temperatures to prevent degradation.
Conflicts
- High heat during processing
- Light exposure
- Potential for allergic reactions in individuals with milk allergies
Safety
Safety Profile
Nonfat Dry Colostrum has not been formally evaluated by the CIR or SCCS. While bovine colostrum and similar supplements lack direct FDA regulation, toxicological evaluations of ultrafiltered bovine colostrum have confirmed its safety, with studies in rats showing no adverse effects at 3% and 10% concentrations over 90 days. Human pre-study tests with a 15% sheep colostrum cream on 25 volunteers reported no sensitizing or irritating effects. However, due to its protein content, a low risk of allergic reactions exists for individuals with milk protein sensitivities, though it is generally considered less reactive than whole milk. A rare case of anaphylaxis from a bovine colostrum cream has been documented.
