Science
Mechanism of Action
As a key amino acid, Ornithine functions as an active ingredient in advanced skin-plumping complexes, notably by activating the transcription factor HIF-1α. This activation is understood to stimulate an increase in fatty tissue volume, leading to a non-invasive 'lipofilling-like' effect within the skin. Beyond its volumizing action, Ornithine actively promotes collagen synthesis, aids in maintaining skin's natural elasticity, and supports cellular regeneration. It also serves as a crucial precursor for polyamines, such as putrescine and spermine, which are integral for increasing vital protein synthesis and enhancing the epidermal barrier function.

Key findings
- 01 In a 60-day in-vivo trial involving 20 volunteers, a 2% cream containing Ornithine, applied twice daily, yielded significant improvements. Manufacturers observed up to a 37.6% reduction in wrinkle depth and up to a 27.5% reduction in skin roughness, with notable efficacy on deep wrinkles like the nasolabial fold.
