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.
Tocopheryl acetate is a stable form of vitamin E, a fat-soluble antioxidant that helps protect skin from damage caused by free radicals and oxidative stress. It's commonly used in skincare products because it's more shelf-stable than other vitamin E forms and may help support the skin's natural barrier function.
Benefits
Antioxidant protection against environmental damage
Supports skin barrier health
Stable ingredient with good shelf life in formulations
Science: Tocopheryl acetate is a well-established vitamin E ester that the body converts to free vitamin E for use. Research shows it functions as a lipid-soluble antioxidant; one recent study found it contributed to a moisturizer's beneficial effects on skin microbiota balance in atopic dermatitis models, though more direct clinical evidence on topical efficacy is limited.
Neopentyl Glycol Diheptanoate is a synthetic emollient and skin-conditioning agent that helps soften and smooth the skin. It's an ester made from neopentyl glycol and heptanoic acid, commonly used in cosmetics to improve texture and spreadability of formulations.
Benefits
Softens and conditions skin
Improves product texture and ease of application
Lightweight emollient that doesn't feel greasy
Science: Research demonstrates that Neopentyl Glycol Diheptanoate can be synthesized through enzymatic pathways with high purity (95% conversion) without additional purification steps, supporting its safety profile for cosmetic use. Limited peer-reviewed safety or efficacy data specifically addressing this ingredient's performance on human skin.
