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.

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.

Disodium EDTA is a chelating agent that binds to metals and minerals in skincare formulations, helping to preserve product stability and extend shelf life. It's used in small amounts (typically under 2%) to prevent unwanted chemical reactions that could degrade the formula.
Benefits
- Stabilizes cosmetic formulations by binding trace metals
- Extends product shelf life and maintains efficacy
- Allows other skincare ingredients to work more effectively
Potential concerns
- May increase skin penetration of other ingredients by chelating calcium in the skin barrier—only a concern if combined with potentially harmful substances
- Not absorbed through skin in normal use, but inhalation from sprays was identified as a theoretical concern in safety assessments
Science: The Cosmetic Ingredient Review Expert Panel confirmed safety in 2023 based on standard use concentrations. Clinical studies show no skin absorption; however, it can affect how other chemicals penetrate the skin, so formulators must account for this when combining with other actives.

Sodium Hydroxide is a strong alkaline chemical used in skincare products primarily as a pH buffer to neutralize acids and adjust the product's pH to safe levels for skin. It is not an active skincare ingredient and appears only in trace amounts in finished products.
Potential concerns
- In concentrated form, sodium hydroxide is caustic and can cause severe chemical burns; however, in cosmetic products it is diluted and pH-buffered to safe levels
- Undiluted or highly concentrated sodium hydroxide should never contact skin directly
Science: The provided research discusses sodium hydroxide only in a specialized medical context (10% solution for surgical cauterization of ingrown toenails), which is not relevant to cosmetic skincare use. In properly formulated skincare products, sodium hydroxide is used in minimal concentrations solely for pH adjustment and is considered safe by regulatory bodies including the FDA and EU.

Isopropyl isostearate is a lightweight emollient oil derived from fatty acids. It's used in moisturizers and skincare products to soften skin and help lock in hydration by improving the skin barrier's ability to retain water.
Benefits
- Improves skin barrier function and water retention
- Lightweight feel compared to heavier occlusives like petrolatum
- May help restructure the outer layer of skin for better hydration
Potential concerns
- May be comedogenic (potentially pore-clogging) in susceptible individuals, based on rabbit ear testing
Science: Research shows isopropyl isostearate improves skin's water-retention properties by modifying how lipids are organized in the outer skin layer, rather than simply coating the surface. However, it was flagged as comedogenic in animal studies, so those prone to breakouts should use with caution.
