Butylene glycol is a humectant—a type of ingredient that draws water into the skin and helps it stay hydrated. It's a small, lightweight molecule commonly used in moisturizers to improve hydration without leaving a heavy feel on the skin.
Benefits
Increases skin hydration and moisture retention
Lightweight and absorbs quickly
Helps other active ingredients penetrate the skin more effectively
Science: Research demonstrates that butylene glycol, when combined with other humectants (like glycerin and hyaluronic acid) and occlusive ingredients in moisturizers, significantly improves skin hydration in both healthy skin and compromised skin conditions such as atopic dermatitis. It is recognized as a safe, effective humectant in dermatological formulations.
Sodium hyaluronate is the salt form of hyaluronic acid, a naturally occurring substance found in your skin that acts like a moisture magnet. In skincare products, it absorbs water from the environment and binds it to your skin, helping to hydrate and plump the skin's surface.
Benefits
Delivers intense hydration to the skin
Helps reduce the appearance of fine lines by improving skin moisture
Supports skin barrier function
Suitable for all skin types, including sensitive and oily skin
Potential concerns
In very dry climates with low humidity, it may draw moisture from deeper skin layers if not sealed with an occlusive product
Rare allergic reactions are possible but extremely uncommon
Science: While the provided research focuses on intra-articular injections for joint health (showing good safety and efficacy), hyaluronic acid and its salt form are well-established in dermatology for topical hydration. The molecule's safety profile is well-documented across decades of use in medical and cosmetic applications, with severe adverse reactions being extremely rare.
Caprylyl glycol is a preservative and skin-conditioning ingredient derived from coconut oil. It helps prevent bacterial and mold growth in skincare products while also providing mild hydrating and humectant benefits to the skin.
Benefits
Helps preserve product freshness and prevent contamination
Provides gentle humectant properties to help retain skin moisture
Often used as a gentler alternative to traditional preservatives
Potential concerns
Rare cases of allergic contact dermatitis have been reported in sensitive individuals
May cause irritation in those with known sensitivity to glycols
Science: A 200-subject repeat patch test study found no delayed hypersensitivity reactions to caprylyl glycol at typical use concentrations. However, isolated case reports of allergic contact dermatitis exist, suggesting it can act as an allergen in susceptible individuals. It is widely used in infant and sensitive-skin formulations as a preservative alternative.
Panax Ginseng Root Extract is a plant-derived ingredient made from the roots of the ginseng plant, traditionally used in skincare for its antioxidant properties. It contains active compounds that may help protect skin from environmental damage and support a more even skin tone.
