Recommended Usage
- Application Frequency:
- Once daily for sensitive or reactive skin.
- Twice daily (morning and evening) for optimal results in normal to resilient skin.
- Application Timing:
- Apply after cleansing before moisturiser and sunscreen.
- Morning use is particularly beneficial due to antioxidant protection against environmental stressors.
Expected Outcomes
- Short-term (2–4 weeks): Improved hydration, smoother skin surface, and enhanced radiance.
- Medium-term (6–12 weeks): Noticeable reduction in fine lines, improved firmness, and increased elasticity.
- Long-term (3+ months): Sustained collagen support, reduction of deeper wrinkles, and reinforcement of dermal density.
Clinical Positioning
- Dermatological Relevance: Positioned as a cosmeceutical adjunct to professional anti-aging regimens.
- Target Audience: Individuals aged 30+ experiencing early to advanced signs of photoaging or intrinsic aging.
- Complementary Use: Can be combined with retinoids, hyaluronic acid serums, or professional treatments (e.g., microneedling, chemical peels) for synergistic effects.
Mechanism of Action
- Peptide Complexes: The serum contains bioactive peptides (such as acetyl hexapeptide-8 and dipeptide diaminobutyroyl benzylamide diacetate) that signal fibroblasts to increase collagen production, reinforcing dermal structure.
- Antioxidants (Vitamin C derivatives): Vitamin C stabilizes collagen fibers, reduces degradation, and protects against oxidative stress. It also replenishes Vitamin E, enhancing photoprotection.
- Matrix Reinforcement: By reducing matrix metalloproteinase (MMP) activity, the serum helps prevent collagen breakdown, maintaining dermal density.
- Hydration & Skin Barrier Support: Gluconolactone and other humectants improve hydration, indirectly supporting collagen synthesis and skin resilience.
Clinical Studies
- Peptide-Based Serum Studies
- A 2026 study in the International Journal of Cosmetic Science demonstrated that a serum containing acetyl hexapeptide-8, dipeptide diaminobutyroyl benzylamide diacetate, and gluconolactone improved biomarkers of collagen activity, reduced wrinkles, and enhanced skin texture in both ex vivo and clinical settings.
- Vitamin C Mechanism & Trials
- Reviews confirm Vitamin C’s role in collagen synthesis, stabilization, and photoprotection, with clinical applications in anti-aging and pigmentation reduction.
- SkinCeuticals RHC Serum Clinical Trial (2024)
- A prospective, randomized, split-face controlled trial evaluated SkinCeuticals recombinant humanized collagen (RHC) serum combined with injectable type III collagen.
- Results showed improved plumpness, firmness, elasticity, and reduction of fine lines compared to control cream.
- Participants were assessed using VISIA imaging and FACE-Q satisfaction scales, confirming both objective and subjective improvements.
