Fragrance Blend F.I.L. c51607/1
INCI: Parfum (Fragrance)
A generic fragrance blend that adds scent but may cause irritation in sensitive skin.
In plain English
This is a mixture of scented ingredients (often essential oils or synthetic aroma chemicals) that gives a product its smell. The code 'F.I.L. c51607/1' is an internal identifier used by some brands to track the specific blend. Because the exact formula is proprietary, it's hard to know which individual fragrance allergens are present, which can be a concern for people with allergies or very sensitive skin.
