Ethylhexylglycerin is a preservative and antimicrobial ingredient used to prevent bacterial growth and extend shelf life in skincare products. It's a multifunctional ingredient that helps keep formulations stable and free from contamination.
Benefits
Prevents bacterial contamination in products
Helps extend product shelf life
Works synergistically with other preservatives for enhanced protection
Potential concerns
May not be effective against all bacterial species (notably some Pseudomonas aeruginosa strains)
Preservative-related sensitization possible in sensitive individuals, though uncommon
Science: Research shows ethylhexylglycerin has broad antimicrobial activity against many common cosmetic contaminants, though effectiveness varies by bacterial species. Studies demonstrate it can work synergistically with other preservative components to enhance biofilm inhibition.
Triethylhexanoin is a lightweight synthetic oil used in skincare products to soften and smooth the skin. It acts as an emollient and helps products glide on easily while creating a subtle protective layer on the skin's surface.
Benefits
Smooths and softens skin texture
Lightweight feel without heaviness
Helps other ingredients spread evenly across skin
Science: Limited peer-reviewed data available for this ingredient. It is chemically similar to other well-established synthetic esters used in cosmetics and has a history of safe use in personal care formulations.
2-Hexanediol is a humectant and preservative booster commonly used in skincare products to help retain moisture and extend shelf life. It works by drawing water into the skin while also enhancing the effectiveness of other preservatives, allowing brands to use lower amounts of traditional preservatives.
Benefits
Hydrates and moisturizes skin by drawing in water
Helps preserve products with lower preservative levels
Works synergistically with other skincare ingredients like niacinamide
Potential concerns
May cause cell viability concerns at concentrations above 1.0% in laboratory studies
Limited real-world safety data in humans at typical skincare concentrations (usually 2-5%)
Potential environmental concern if released into water systems
Science: While 2-hexanediol is widely used as a preservative substitute for parabens, recent cytotoxicity studies raise questions about safety at concentrations commonly found in skincare products (>2%). However, these findings are from laboratory cell studies and may not directly translate to human skin application. Further human safety studies are needed to confirm real-world risk.
Niacinamide is an active form of vitamin B3 that works within your skin's cells to strengthen the barrier, reduce inflammation, and regulate oil production. It's a water-soluble ingredient that's been shown to have multiple benefits across different skin concerns, from sensitivity to aging.
Benefits
Reduces redness and calms irritation
Minimizes pore appearance and controls excess oil
Supports skin barrier function and hydration
Brightens skin tone and evens complexion
Has anti-aging properties and protects against environmental damage
Science: Niacinamide is well-tolerated and safe across diverse skin types with strong clinical evidence supporting its use for acne, dermatitis, and general skin health. Research shows it works by regulating inflammation at the cellular level and protecting skin barrier integrity, with proven efficacy in concentrations commonly found in cosmetic products.
Adenosine is a naturally occurring compound found in all living cells that plays a role in skin cell energy production and communication. In skincare, it's used to help support skin barrier function and may promote a smoother, more resilient complexion.
Benefits
Supports skin barrier strength and integrity
May help reduce the appearance of fine lines and wrinkles
Promotes skin cell energy metabolism and repair
Science: Research indicates adenosine and related compounds (like cyclic adenosine monophosphate) regulate skin barrier formation and epidermal differentiation. While direct clinical studies on topical adenosine in skincare are limited, the ingredient's role in cellular energy and barrier maintenance is well-established in dermatological literature.
Methylpropanediol is a lightweight humectant and preservative booster commonly used in skincare formulations. It helps products stay stable while drawing moisture into the skin, making it useful in serums, moisturizers, and other hydrating products.
Benefits
Humectant that helps skin retain moisture
Enhances the preservative system in formulations
Light texture that absorbs easily without greasiness
Science: Research confirms methylpropanediol functions effectively as a polyol solvent in cosmetic formulations and is recognized as a safe alternative preservative booster. The ingredient has been validated in quality control testing of commercial skincare products with good safety margins.
