Full ingredient details →
MethylpropanediolGenerally safe

A small glycol used as a solvent and to boost the absorption of actives, and to help preservatives work at lower levels. It is well tolerated and graded low concern in published assessments.

Aloe VeraGenerally safe

Full ingredient details →
Lactic AcidWatch if sensitive

A larger, gentler alpha hydroxy acid than glycolic acid, used to exfoliate and to draw in moisture. It can still cause stinging or increased sun sensitivity at higher concentrations, so daytime SPF use is sensible, but it is generally better tolerated than glycolic acid.

PanthenolGenerally safe

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

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

Full ingredient details →
Xanthan GumGenerally safe

Full ingredient details →
CarbomerGenerally safe

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.

Full ingredient details →
Sodium PhytateGenerally safe

Sodium phytate is a plant-derived chelating agent used to bind trace metals and stabilize formulas, often as a preservative booster alongside other preservatives. Available safety reviews have not identified meaningful irritation or sensitization concerns at typical use levels.

Full ingredient details →
Potassium SorbateGenerally safe

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.

Full ingredient details →
Sodium BenzoateGenerally safe

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.

Full ingredient details →
HydroxyethylcelluloseGenerally safe

A cellulose derivative used to thicken and stabilize formulas. It dissolves fully in water and does not separate or settle over time. It is well tolerated and widely used in gels, lotions, and serums.

Full ingredient details →
Pentylene GlycolGenerally safe

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.

Full ingredient details →
EthylhexylglycerinGenerally safe

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

Full ingredient details →
PhenoxyethanolCommonly feared, low concern

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.
