Firming Perfector Serum

A light coconut-derived emollient ester used as a natural-feeling alternative to silicones, giving a dry, velvety finish. It is well tolerated and graded low concern in published assessments.

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

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

Natural corn starch used to absorb excess oil and add body to cosmetic formulas. It is very well-tolerated and has a long history of safe use in personal care.

A naturally derived humectant made from fermented plant sugars that draws water into the skin. It is well tolerated in cosmetics and is used to support hydration and skin softness.

Sodium PCA is a natural component of skin's own moisturizing factor and is used in cosmetics as a humectant to help skin hold onto water. It has an extensive history of safe use with no meaningful irritation or sensitization 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 fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

A preservative booster and antioxidant derived from natural sugars. Often used alongside other preservatives to enhance efficacy and extend shelf life.

A humectant that holds water at the skin surface for a more hydrated look. No safety concern.

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

A protein fragment from rice that helps bind water and strengthen hair. It is mild and well tolerated, making it a suitable option for those seeking a plant-derived protein conditioner without the allergen concerns of wheat or other grain proteins.

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

A nutrient-rich carrier oil from soybean seeds containing linoleic and linolenic acids essential for barrier function. Phytoestrogen content is present but not absorbed systemically from topical application, graded low concern by regulatory assessments.

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.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.

A salt derived from citric acid that buffers pH and prevents metal oxidation in formulas. Widely used in food and cosmetics, it is well tolerated at cosmetic concentrations.

A widely used, gentle preservative also common in food. It is generally well tolerated, though it can occasionally cause mild, transient irritation in people with already-compromised or very reactive skin.

The sodium salt of benzoic acid, used as a preservative in both foods and cosmetics. Decades of safety review support its use at typical cosmetic concentrations, with mild irritation the main reported issue in sensitive skin.
