Neryl Butyrate
INCI: NERYL BUTYRATE
Neryl butyrate is a synthetic fragrance ester that adds a pleasant fruity-floral note to products, but offers no skincare benefits and may cause sensitivity in those with fragrance allergies.
In plain English
Neryl butyrate is a man-made ingredient that smells like a mix of fruit and flowers. It's added to skincare and beauty products just for its scent, not to improve your skin. Because it's a fragrance, it can sometimes cause irritation or allergic reactions, especially if you have sensitive skin or a known fragrance allergy.
