Vegetable glycerin

Glycerin is a natural humectant that attracts and retains moisture in the skin, thereby increasing its hydration, elasticity, and softness¹.
It is derived from vegetable oils through hydrolysis or saponification and is a biodegradable, non-toxic ingredient that helps improve the skin’s protective barrier function².

Glycerin has been proven to reduce transepidermal water loss (TEWL), promote epidermal regeneration, and enhance the skin’s resistance to external stressors³ ⁴.
