Ingredient review
Fragrance Blend
INCI: F.I.L. c170899/1
A generic fragrance blend that adds scent but may cause irritation for sensitive skin.
In plain English
This is a fragrance blend, meaning a mix of synthetic and natural aroma chemicals that give a product its smell. It doesn't do anything for your skin's health—it's purely for sensory appeal. Because the exact formula is proprietary, it's hard to know which specific ingredients are inside, which can be a concern if you have allergies or sensitivities.

What it is
A proprietary fragrance compound identified by a manufacturer's internal code (F.I.L. c170899/1), likely containing a mixture of synthetic aroma chemicals and possibly natural essential oils.
