Pantolactone
Ingredient Info
Pantolactone is a naturally occurring compound and the precursor to panthenol (provitamin B5). In skincare products, it's used for its potential skin-conditioning and moisturizing properties, though it's less commonly used than its converted form, dexpanthenol.
Benefits
- May support skin hydration and moisture retention
- Potential skin-conditioning properties
- Naturally derived ingredient
Potential concerns
- Allergic contact dermatitis has been documented in sensitive individuals, particularly in wound-healing creams
- May cause skin irritation or allergic reactions in susceptible people
Science: A 2022 Contact Dermatitis study identified allergic contact dermatitis cases linked to pantolactone in wound-healing formulations, indicating it can trigger immune responses in some users. Limited additional peer-reviewed data is available on its efficacy and safety profile in general skincare applications.
