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.
Trehalose is a naturally occurring sugar (disaccharide) used in skincare products for its stabilizing and protective properties. It helps preserve the integrity of skin cells and other ingredients, particularly when exposed to environmental stressors like heat or dryness.
Benefits
Helps stabilize and protect skin cells from damage
May improve skin barrier function and reduce moisture loss
Supports ingredient stability in formulations
Science: Trehalose is widely recognized in biopharmaceutical and cosmetic industries for its cryoprotective and stabilizing properties. While peer-reviewed evidence specifically for topical skincare benefits is limited, research demonstrates its effectiveness as a cellular protectant and its ability to enhance the uptake and efficacy of other beneficial compounds in tissues.
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.
Sodium phytate is a naturally derived ingredient that acts as a chelating agent, binding to minerals and metals on the skin's surface. In skincare, it's primarily studied for its potential brightening and clarifying properties, though research in this area remains limited.
Benefits
May help brighten skin appearance
Potential mild exfoliating or clarifying effect
Naturally derived ingredient
Potential concerns
Very limited safety data in skincare applications
Chelating agents can potentially disrupt skin barrier minerals if used excessively
Most research focuses on dental use rather than facial skincare
Science: Available research on sodium phytate focuses primarily on dental whitening toothpaste rather than skincare products. One 2025 clinical trial showed modest whitening effects in toothpaste formulations over 3-4 weeks, but efficacy plateaued. Peer-reviewed safety and efficacy data specifically for facial skincare use is limited.
Sodium hyaluronate is the salt form of hyaluronic acid, a naturally occurring substance found in your skin that acts like a moisture magnet. It can hold up to 1000 times its weight in water, making it excellent for hydrating and plumping the skin.
Benefits
Intense hydration and moisture retention
Reduces appearance of fine lines and wrinkles by plumping skin
Suitable for all skin types including sensitive and acne-prone skin
Science: Sodium hyaluronate is well-established in skincare research and has a strong safety profile with minimal irritation potential. Studies consistently demonstrate its effectiveness at improving skin hydration and elasticity when used in concentrations typical of consumer products.
