Hydro Boost Aqua-Gel — ingredient safety report

• Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
• Irritation:Frequent trigger of stinging and redness on reactive skin.

An umbrella term that can hide dozens of undisclosed scent chemicals. Fragrance is the leading cause of allergic contact dermatitis from cosmetics, and dermatologists routinely advise fragrance-free products for eczema, babies and sensitive skin.

• Irritation:Occasional stinging and irritation, mostly around eyes and on damaged skin.

Today's most common preservative, considered safe by the SCCS up to 1%. French authorities advise avoiding it in wipes and diaper-area products for children under 3 as a precaution.

• Irritation:Can irritate sensitive or compromised skin.

A synthetic preservative capped at 0.3% in the EU; generally tolerated but a known occasional irritant.

• Irritation:Documented occasional contact allergy and eye irritation.

A preservative booster often paired with phenoxyethanol; low-risk overall with rare reports of contact allergy.

• Environmental impact:Not biodegradable; accumulates in the environment via wash-off.

The workhorse silicone — inert and non-sensitizing on skin (even FDA-approved as a skin protectant), with persistence in the environment as its main criticism.

• Environmental impact:Persistent silicone, like dimethicone.

A silicone gum for silky slip; skin-inert with the family's usual environmental-persistence criticism.

• Allergy risk:Rare reports of sensitivity.

A widely approved blue dye with a benign cosmetic safety record.
