Ultra Glow Serum: Glow + Strengthen Vitamin C Serum

The base most products are built on. It carries the other ingredients and has no safety concern.

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.

A polyethylene glycol ester of hydrogenated castor oil, widely used as an emulsifier and solvent in rinse-off and leave-on cosmetics. PEG-modified ingredients are graded as safe in cosmetics by the CIR when formulated at typical use levels.

Carbomer is a synthetic polymer used purely to thicken and stabilize gels and lotions, with negligible skin penetration due to its large molecular size. Safety reviews have found low toxicity and minimal irritation potential even in leave-on use.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

A strong alkali used in tiny amounts to adjust the pH of cosmetics to safe, skin-friendly levels. At the pH found in finished products, sodium hydroxide is neutralized and well tolerated.

A plant-derived emollient and preservative formed from glycerin and caprylic acid (coconut) that helps retain moisture and supports formula stability through mild antimicrobial activity.

A gentle, sugar-derived surfactant that is milder than sulfates and works through natural emulsification without the irritation profile of harsher cleansers. It is well-established in rinse-off and leave-on formulations.

A hydrating plant extract from sugarcane rich in amino acids and minerals. It conditions and softens skin and is generally well tolerated across skin types.

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

A cold-pressed oil from sweet orange peel with a bright, citrus scent, containing furanocoumarins that can cause phototoxic reactions (pigmentation and irritation) when exposed to sunlight. This oil is best reserved for rinse-off products or formulations where sun exposure is unlikely or protected, as it can trigger adverse reactions in reactive individuals on sun-exposed skin.

A citrus essential oil with a fresh scent, extracted from lemon peel. It contains recognized fragrance allergen constituents (limonene, citral) and can trigger contact reactions in fragrance-sensitive individuals. Additionally, citrus peel oils carry documented phototoxicity risk, meaning skin treated with the product should avoid direct sunlight.

A soothing humectant that helps skin and hair look conditioned. Very well tolerated.

A green microalgae extract containing chlorophyll, proteins, and antioxidants, used in skincare formulations for antioxidant and conditioning benefits. Published assessments indicate good tolerability in cosmetic applications, though sensitive individuals may want to patch test first.

A linoleic-acid-rich plant oil used as an emollient and, in some small pediatric studies, associated with support of the skin barrier when applied to infant skin. It is well tolerated with a low reported rate of contact reactions.

A gentle, stable vitamin C derivative that the skin converts to active vitamin C, popular for brightening with less irritation than pure ascorbic acid. It is well tolerated and graded low concern in published assessments.

An antioxidant that helps protect a formula and condition skin. Well tolerated.

An aromatic plant extract rich in natural antioxidants, valued in skincare formulations for its protective properties. Published cosmetic assessments indicate it is generally well tolerated, though the botanical origin means some sensitive individuals may react.
