Body Serum

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.

A lightweight, silicone-like emollient derived from coconut/palm fatty alcohols, used to give lotions a smoother, less greasy feel. Listed in the EU CosIng database as a skin-conditioning agent with no restrictions.

A synthetic polymer used to thicken and stabilize water-based formulas like gels and serums. It provides texture and suspension of particles without interfering with skin feel. Well established in cosmetics.

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

A form of vitamin B3 used to support a more even-looking tone and a comfortable barrier. Well tolerated at cosmetic levels.

A lab-made version of a lipid naturally found in the outer skin barrier. It is added to creams and cleansers to help replace lipids that washing can strip away, and it is not linked to irritation or safety concerns.

Gluconolactone is a polyhydroxy acid that exfoliates gently while also acting as a humectant and mild antioxidant, and it is generally recommended for sensitive or barrier-compromised skin over smaller AHAs. A full cosmetic panel review found it safe as used, though some users still report mild stinging or redness at higher concentrations.

An emulsifier made from glycerin and stearic acid that stabilizes oil-in-water and water-in-oil formulations. It has a long history of safe use in cosmetics and is assessed as a low-concern ingredient in published safety reviews.

A phospholipid emulsifier from soy or sunflower that binds water and oil and helps other ingredients absorb. It is a natural component of skin membranes, well tolerated, and reviewed as safe as used; a soy-derived grade is not a meaningful concern for a soy food allergy because the protein is largely absent.

A gentle sugar-and-fatty-acid emulsifier that binds water and oil, favored in formulas for sensitive skin. It is well tolerated and graded low concern in published assessments.

A plant-derived water or extract used mainly as a soothing humectant filler. Evidence for dramatic skin benefits beyond mild hydration and soothing is limited, but it is well tolerated by most people.

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.

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

A biodegradable chelating agent that binds trace metals to stabilize formulas, often chosen as a gentler alternative to EDTA. It is readily degraded in the environment and poses minimal toxicity concerns 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.

An antioxidant and preservative salt that prevents oxidation and microbial growth in formulations. It is well tolerated for most users, though people with sulfite sensitivity should avoid it; those without documented sulfite intolerance can use products containing it without concern.
