Synthetic Fragrance
Synthetic fragrances are lab-made scent compounds added to give products a pleasant smell. The specific ingredients are rarely disclosed on the label, and they're a leading cause of skin irritation, sensitization, and allergic reactions, particularly for sensitive skin.
Fragrance
Fragrances make products smell appealing but are a common cause of skin irritation and allergic reactions. This includes synthetic fragrances, natural fragrances, and essential oils. Fragrance-free products are the safest bet for sensitive skin.
May cause Irritation
Some ingredients have higher irritation potential, particularly for sensitive skin. Common reactions include redness, burning, or itching. If you have sensitive skin, patch test first and introduce these ingredients slowly into your routine.

Explained
Rose Ketone-4 is a synthetic fragrance that has a rosy, floral scent.
The Scientific Committee on Consumer Safety (SCCS) has classified Rose Ketone-4 as an established contact allergen in humans with a moderate sensitizing potency based on animal studies.
However, it is considered a rare sensitizer because documented reactions in real-world users are uncommon.
In terms of regulation, this ingredient has been capped at 0.02% in finished cosmetic products under EU (and UK) cosmetic regulations since 2013.
