These proprietary microparticle delivery systems provide sustained release of hydroquinone, extending efficacy to improve uneven skin tone and/or hyperpigmentation.

Clinical studies have proven that products containing microparticle entrapped hydroquinone, in combination with entrapped retinol, provide greater efficacy in improving the appearance of skin tone. Additionally, this technology enhances the stability of hydroquinone in formulation reducing discoloration in finished product.
