Glycerin is a naturally derived humectant—a ingredient that draws moisture from the air into your skin. It's one of the most widely used and well-studied moisturizing agents in skincare, helping skin feel softer and more hydrated.
Benefits
Attracts and retains moisture in the skin
Improves skin hydration and softness
Helps strengthen skin barrier function
Suitable for most skin types, including sensitive skin
Science: The Cosmetic Ingredient Review Expert Panel concluded glycerin is safe as used in cosmetics across all concentrations. Research shows glycerin effectively improves skin hydration and is well-tolerated with minimal irritation risk. It is also referenced in clinical guidelines for managing inflammatory skin conditions and maintaining skin integrity.
Alcohol (typically ethanol) is a volatile liquid commonly used in skincare products as a preservative, solvent, and to help products dry quickly on skin. It can penetrate the skin barrier and is often included to improve product texture and shelf stability.
Benefits
Preservative properties that help prevent bacterial and fungal growth
Quick-drying formula that feels lightweight
Helps dissolve and distribute other ingredients evenly
Potential concerns
Can strip skin of natural oils and cause dryness, especially with repeated use
May irritate sensitive skin or compromise the skin barrier
Can cause stinging or burning sensation on compromised or reactive skin
May increase skin sensitivity to sun exposure
Science: Recent cosmetic science literature shows growing interest in alcohol-free formulations due to skin barrier concerns. The provided research focuses on deodorants, noting that alcohol-free alternatives are increasingly preferred in product development, though alcohol remains widely used in skincare for its preservative and solvent functions.
Cucumber fruit extract is a plant-derived ingredient made from pressed or fermented cucumber. It's lightweight and contains natural compounds like vitamins, minerals, and antioxidants that can help soothe and hydrate skin.
Benefits
Hydrating and refreshing
May help soothe mild irritation or redness
Light antioxidant properties
Science: Limited peer-reviewed data available for this ingredient. Cucumber is generally recognized as very safe in cosmetics and has a long history of traditional use in skincare, though specific efficacy claims lack robust clinical support.
This is a liquid extract made by fermenting daikon radish with Leuconostoc bacteria. It functions primarily as a natural preservative in skincare products, helping prevent bacterial and microbial growth to extend shelf life.
Benefits
Natural preservative that helps prevent bacterial contamination
May have mild antimicrobial properties on skin
Derived from fermented ingredients, appealing to 'clean beauty' preferences
Potential concerns
Salicylic acid content may cause irritation or dryness in sensitive skin
Potential allergic reactions in individuals sensitive to radish or fermentation byproducts
Limited safety data at typical cosmetic concentrations
Science: Research shows this ingredient's antimicrobial activity comes from salicylic acid (active against Gram-negative bacteria) and didecyldimethylammonium salts (active against Gram-positive bacteria), rather than from fermentation-produced compounds as traditionally claimed. However, peer-reviewed data on its safety and efficacy specifically in skincare formulations at cosmetic use levels is limited.
