Ingredients that prevent moisture loss work by forming an occlusive layer or by attracting and binding water in the stratum corneum, reducing transepidermal water loss (TEWL). They support the skin barrier and improve hydration but are generally not therapeutic actives.
| Reported effect | How often | Notes |
|---|---|---|
Contact irritation or stinging | Uncommon | More likely on compromised or sensitive skin |
Acne or comedone formation | Uncommon | Associated with heavier occlusives in acne-prone individuals |
Allergic contact dermatitis | Rare | Typically linked to specific emollient or preservative components |
Folliculitis | Rare | Occlusion can trap bacteria in some users |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
