"No synthetic fragrances" indicates a product formulated without artificial fragrance compounds, often to reduce the risk of fragrance-related skin reactions. It is a formulation choice rather than an active ingredient, though products may still contain natural fragrance materials or essential oils that can cause sensitivity.
| Reported effect | How often | Notes |
|---|---|---|
| Allergic contact dermatitis from natural fragrance substitutes (e.g., essential oils) | Uncommon | Fragrance-free claims do not guarantee absence of botanical allergens like limonene or linalool |
| Irritant contact dermatitis | Rare | Possible if natural aromatic substitutes are used in place of synthetics |
| Sensitization to botanical extracts | Rare | Plant-derived scents can still provoke reactions in predisposed individuals |
Frequencies reflect typical cosmetic use reported in the literature, not a guarantee for your skin.
