ARGININE
Arginine is a semi-essential amino acid naturally present in the skin and body, where it plays a vital role in maintaining skin health and structure. In skincare formulations, it is valued not only for its moisturizing and protective qualities but also for its ability to support the skin’s natural repair processes and strengthen the barrier function.
As a key component of the skin’s Natural Moisturizing Factor (NMF), arginine enhances skin hydration by attracting and retaining water within the stratum corneum. This makes it especially effective in improving skin elasticity, softness, and overall resilience. Clinical studies have shown that topical arginine helps reduce transepidermal water loss (TEWL), resulting in visibly more hydrated and supple skin.
Arginine offers potent antioxidant properties, helping to neutralize free radicals that contribute to premature aging. By reducing oxidative stress, it supports the skin’s defenses against environmental aggressors, preserving both texture and tone.
It also plays a crucial role in wound healing and tissue regeneration. As a precursor to nitric oxide (NO) – a molecule essential for vasodilation and immune modulation – it supports microcirculation and cellular repair. It also promotes collagen synthesis, making it especially beneficial in formulations targeting sensitive, damaged, or aging skin by helping to reduce the appearance of fine lines and wrinkles.
The Arginine used in LAST formulations is 100% plant-derived, produced through natural fermentation. It is vegan, Halal-certified, and COSMOS-approved.
