Key ingredients

Propanediol
Propanediol, a glycol derived from corn sugar or synthetic processes, is a humectant and solvent with moisturizing properties. It works by drawing moisture into the skin, improving hydration levels. Propanediol is a penetration enhancer that increases absorption of other ingredients in the skin care routine. It is a natural alternative to propylene glycol, offering similar benefits with less irritation. Use to improve the texture and stability of formulations, resulting in enhanced product performance and increased shelf life.

Helianthus Annuus (sunflower) Sprout Extract
Helianthus Annuus (Sunflower) Sprout Extract boosts cellular energy with ATP, defends against oxidative stress, and reduces glycation damage. Rich in antioxidants and omega-3s, it enhances firmness, smooths texture, and strengthens the skin barrier for visibly healthier, more resilient skin.
