What it is
A gamma-lactone compound extracted from rapeseed oil, belonging to a class of cyclic esters known for their skin-conditioning and mild exfoliating effects.
How it works
It works by gently breaking down the bonds between dead skin cells on the surface, promoting natural shedding and revealing fresher skin. Additionally, it helps retain moisture in the outer layer of the skin, supporting a softer, smoother feel.
Pros
Gentle on skin
Unlike stronger acids like glycolic acid, rapeseed gamma-lactone provides mild exfoliation that is less likely to cause redness or stinging, making it ideal for sensitive skin.
Moisturizing effect
It helps the skin retain moisture while exfoliating, so you get smoother skin without the dryness often associated with exfoliants.
Cons and cautions
Limited research
There are fewer studies on rapeseed gamma-lactone compared to more common exfoliants, so its long-term benefits and safety are less established.
Mild efficacy
For those with significant texture concerns or clogged pores, this ingredient may not provide enough exfoliating power on its own.
Best for
- People with sensitive or dry skin seeking mild exfoliation
- Those looking for plant-derived alternatives to traditional acids
Use caution if
- Individuals with very oily or acne-prone skin who need stronger exfoliation
