What is Phenylethyl Resorcinol? 

Phenylethyl Resorcinol - Potent skin brightening agent

Phenylethyl Resorcinol, a synthetic and stable compound, stands out with its potent inhibition ability in tyrosinase bioactivities, a critical enzyme in melanin synthesis. It surpasses kojic acid in strength, safety, and stability, outperforms hydroquinone in safety, and is more effective than AHAs and vitamin C in addressing skin lightening and hyperpigmentation concerns.

Phenylethyl resorcinol, a potent skin-lightening agent, is often chosen as a safe alternative to hydroquinone without known side effects. Visible results can often be seen within just 4 weeks.

It also provides antioxidative properties for skin protection and anti-aging benefits. Its antioxidant power is equally strong as BHT and alpha-tocopherol.  

Phenylethyl resorcinol is gentle to the skin but has no known side effects.

Skin Benefits: 

1. Lightens and fades dark spots and patches
2. Lightens the skin tone
3. Fades post-inflammatory hyperpigmentation (PIH), such as pigmentated acne marks
4. Skin protection against oxidative stress
