- Irritation:Drying and barrier-disrupting in high-alcohol formulas with regular use.

- Allergy risk:EU-declarable allergen; oxidized linalool is a common patch-test positive.
A floral scent molecule found in lavender and many essential oils. It oxidizes on air exposure into strongly sensitizing compounds, which is why it must be declared on EU labels.

- Allergy risk:American Contact Dermatitis Society Allergen of the Year 2018.
- Irritation:Can irritate compromised skin at higher concentrations.
A workhorse humectant and penetration enhancer that is fine for most, but a recurring culprit in eczema patients' patch tests.

- Irritation:Milder than glycolic; still increases photosensitivity.
A gentler AHA that exfoliates and hydrates simultaneously; the usual pick for drier or more reactive skin starting acids.
- Irritation:Can cause transient, non-allergic flushing/stinging on reactive skin.
A food-grade preservative generally regarded as one of the gentler options; occasional non-immune stinging is its main drawback.
