What it is

A synthetic ester compound used as a fragrance ingredient in cosmetics and personal care products. It is created in a lab to produce a specific scent profile.

How it works

It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. It does not interact with skin biology or provide any functional skincare benefit.

Pros

Pleasant scent

Adds a fresh, floral note that can make your skincare routine feel more luxurious and enjoyable.

Low irritation for most

At typical low concentrations, it is unlikely to cause problems for people without fragrance sensitivities.

Cons and cautions

No skin benefit

This ingredient is purely for scent—it doesn't moisturize, protect, or improve skin health in any way.

Potential allergen

Like many fragrance ingredients, it can cause contact dermatitis or allergic reactions in sensitive individuals, especially with repeated use.

Best for

  • People who enjoy scented products and have no fragrance sensitivities
  • Those looking for a light, fresh floral scent in their routine

Use caution if

  • Individuals with sensitive skin, eczema, or known fragrance allergies

Usage tips

If you have sensitive skin, patch test any product containing this ingredient before full use.
Consider fragrance-free alternatives if you notice redness, itching, or irritation after using scented products.
