Can I use Niacinamide with Trifluoroacetyl Tripeptide-2?
Works well together
Niacinamide and Trifluoroacetyl Tripeptide-2 are generally compatible and can be layered in the same routine. As always, introduce one new active at a time and watch how your skin responds.
NiacinamideActive
- ✓Reduces redness and blotchiness
- ✓Supports the skin barrier
- ✓Regulates oil
- ✓Reduces progerin synthesis in aging fibroblasts by ~18–22% — progerin is the truncated lamin A protein that accumulates in mature skin cells and drives cellular senescence, slowing the molecular aging program at the gene level
- ✓Inhibits collagenase (MMP-1/-3) and elastase degradation of structural fibers — in vitro data shows ~43% protection against collagenase and ~100% protection against elastase at the use concentration
- ✓Clinical data (4 ppm, 8 weeks): +20% skin firmness, +20.9% elasticity, reduced jawline sagging volume — plus upregulation of syndecan-1 in keratinocytes and TGF-β signaling enhancement
