Potassium sorbate is a preservative used in skincare products to prevent the growth of mold, yeast, and some bacteria, helping extend shelf life. It's a salt derived from sorbic acid and is commonly used as a gentler alternative to stronger chemical preservatives.
Benefits
Prevents microbial contamination and mold growth
Generally considered milder than some other preservatives like benzalkonium chloride
Allows products to remain effective longer without refrigeration
Potential concerns
May cause irritation or allergic contact dermatitis in sensitive individuals
Not suitable for preservative-free formulations
Limited effectiveness against some bacteria compared to stronger preservatives
Science: Clinical research suggests potassium sorbate is less damaging to delicate tissues than benzalkonium chloride, making it a preferred alternative preservative in sensitive applications like eye products. However, peer-reviewed safety data specific to topical skincare use in the general population is limited.
Ceramide NP is a naturally-derived lipid that mimics ceramides found in healthy skin. It works to repair and strengthen your skin's protective barrier, helping it retain moisture and resist irritation.
Benefits
Restores skin barrier function and structural integrity
Reduces trans-epidermal water loss (helps skin stay hydrated)
Strengthens skin's natural defense against irritants and environmental stressors
Science: Recent research demonstrates that Ceramide NP effectively recovers damaged skin barrier function and can be formulated into advanced delivery systems (like ethosomes) to enhance skin absorption. Studies show it meaningfully lowers water loss while restoring epidermis structure in compromised skin.
