What it is
A synthetic surfactant derived from sulfosuccinic acid, designed to lower the surface tension between water and oils, making it easier to wash away impurities.
How it works
It works by surrounding oil and dirt particles, breaking them into tiny droplets that can be suspended in water and rinsed off. This action helps cleanse the skin and scalp without requiring harsh scrubbing.
Pros
Strong oil removal
Effectively breaks down and removes excess sebum and makeup, leaving skin feeling clean and refreshed.
Good foam quality
Creates a rich, bubbly lather that many people associate with a thorough cleanse, making it satisfying to use.
Cons and cautions
Potential for dryness
Can strip the skin's natural oils, leading to tightness, flakiness, or irritation, especially with frequent use.
Moderate irritation risk
May cause stinging or redness for those with compromised skin barriers or conditions like rosacea.
Best for
- People with oily or combination skin looking for a deep cleanse
- Those who prefer a foamy, satisfying lather in their cleanser
