Tesofensine- Summary
- Syn-Coll is a palmitoylated tripeptide (Palmitoyl Tripeptide-5) that mimics thrombospondin-1 to activate TGF-beta, the primary growth factor driving collagen synthesis in the dermis. It is one of the most mechanistically direct collagen-stimulating peptides in cosmetic formulations.
- Tesofensine is a triple monoamine reuptake inhibitor (TMRI) that blocks reuptake of serotonin, dopamine, and norepinephrine. Originally developed for Alzheimer's and Parkinson's disease, it was repurposed as a potent weight loss agent after clinical trials demonstrated substantial fat loss via appetite suppression and increased energy expenditure.

- Frequency
- Once or twice daily
- Once daily
- Key Benefits
- Directly activates TGF-beta for potent collagen synthesis stimulation
- Increases dermal thickness and firmness
- Reduces depth of wrinkles and fine lines
- Improves skin elasticity
- Clinically validated in collagen induction studies
- Complementary to retinoids or vitamin C
- Potent appetite suppression via triple monoamine reuptake inhibition
- Significant weight loss (8-12% body weight in phase II trials at 0.5 mg)
- Increases basal metabolic rate and energy expenditure
- Reduces fat mass preferentially over lean mass
- Potential cognitive benefit via dopaminergic and noradrenergic enhancement
- Longer half-life than sibutramine allows once-daily dosing
