4-ETHYLRESORCINOL

Description

4-Ethylresorcinol is a potent skin-brightening agent that has gained significant attention in the cosmetic industry for its ability to target hyperpigmentation and uneven skin tone. This synthetic compound is structurally similar to hydroquinone but offers a safer profile with fewer side effects. It functions as a tyrosinase inhibitor, effectively interrupting the melanin production process in melanocytes.

Studies have shown that 4-ethylresorcinol can reduce melanin content by up to 80% at concentrations as low as 0.1%. It demonstrates superior efficacy compared to other common brightening agents like kojic acid and arbutin. The ingredient is particularly effective in addressing age spots, sun damage, and post-inflammatory hyperpigmentation.

In formulations, 4-ethylresorcinol is typically used at concentrations between 0.1% to 1%. It is water-soluble and stable in a pH range of 3.0 to 7.0, making it versatile for incorporation into various skincare products. This compound also exhibits antioxidant properties, offering additional benefits for skin health and protection against environmental stressors.

While generally well-tolerated, some individuals may experience mild irritation. It is recommended to conduct patch testing before widespread use, especially for those with sensitive skin.
