What it is
A synthetic ester derived from resorcinol, modified with ethylhexanoic acid to improve stability and reduce irritation potential.
How it works
It inhibits the enzyme tyrosinase, which is key in melanin production. By slowing melanin synthesis, it helps reduce the appearance of dark spots and uneven pigmentation over time.
Pros

It targets dark spots with a low risk of irritation, making it suitable for sensitive skin types.
Stable formula
As an ester, it remains stable in skincare products, ensuring consistent effectiveness over time.
Cons and cautions

It may take longer to see results compared to stronger brighteners like hydroquinone or high-concentration vitamin C.
Limited research
There are fewer studies on this ingredient compared to more established brighteners, so long-term effects are less understood.
Best for
- People with mild to moderate hyperpigmentation
