What it is
A semi-synthetic derivative of glycyrrhizinic acid, a natural compound from licorice root. The 'hydrolyzed' part means it has been broken down into smaller molecules for better skin absorption.
How it works
It works by inhibiting an enzyme called tyrosinase, which is involved in melanin production, helping to fade dark spots. It also has anti-inflammatory properties that calm redness and irritation by reducing the activity of certain inflammatory pathways in the skin.
Pros
Gentle Soothing
Effectively reduces redness and irritation without the sting or dryness that some other soothing ingredients can cause.
Mild Brightening
Helps even out skin tone and fade dark spots over time, making it a good option for long-term, gentle brightening.
Cons and cautions
Slow Results
Compared to stronger brighteners like vitamin C or prescription treatments, results may take longer to become visible.
Variable Efficacy
Its effectiveness depends heavily on the product formulation and concentration, so not all products will deliver the same benefits.
Best for
- People with sensitive or reactive skin
- Those looking to gently fade dark spots or post-acne marks
