Sodium chloride is common table salt, used in skincare products as a texture modifier, preservative, and to help balance formulations. In small amounts, it's generally well-tolerated by skin.
Benefits
Helps preserve product stability
Can enhance skin hydration when used in appropriate concentrations
Improves product texture and consistency
Potential concerns
High concentrations may irritate sensitive or compromised skin
Excessive topical salt exposure can potentially disrupt skin barrier function
May cause dryness or tightness in some individuals
Science: Sodium chloride is a naturally occurring electrolyte essential to skin physiology. Research indicates the skin actively regulates sodium levels through complex mechanisms involving the endothelium, immune cells, and lymphatics; however, peer-reviewed data specifically addressing topical sodium chloride in cosmetic formulations at typical use levels is limited.
Lemon peel oil is an essential oil extracted from the peel of lemon fruit, commonly used in skincare for its fresh scent and potential brightening properties. It contains natural compounds like limonene and vitamin C that may help invigorate the skin, though its effectiveness depends on concentration and formulation.
Benefits
May provide antioxidant protection
Can add a fresh, uplifting scent
Potentially supports skin brightness and radiance
Potential concerns
Can cause photosensitivity (increased sun sensitivity) when applied topically before sun exposure
May irritate sensitive or compromised skin
Can cause contact dermatitis in sensitive individuals
Science: Limited peer-reviewed data available for this ingredient. General knowledge of citrus essential oils suggests limonene and citral are the primary active compounds, but stability and efficacy in finished skincare products vary widely depending on formulation and concentration.
