- Irritation:Dryness and peeling at exfoliating concentrations (0.5–2%).
The pore-clearing BHA exfoliant. Not for young children (salicylate absorption), used cautiously in pregnancy at low leave-on concentrations, and drying for compromised barriers.

- Irritation:Drying and barrier-disrupting in high-alcohol formulas with regular use.
Denatured ethanol gives products a fast-drying, weightless feel, but as a leading ingredient it degrades the skin barrier with repeated use — a poor match for dry, sensitive or eczema-prone skin.

- Irritation:Stinging, redness and increased sun sensitivity; smallest, deepest-penetrating AHA.
The strongest common AHA exfoliant. Effective for texture and tone but raises sun sensitivity — daytime SPF is essential while using it.

Caredermis curated dermatological review
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: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.
- Environmental impact:Poorly biodegradable; can remobilize heavy metals in waterways.
A metal-binding stabilizer that is safe on skin at the tiny amounts used; its criticism is environmental persistence.
