Polyhydroxy Acids (PHAs) are a new generation of chemical exfoliants known for their larger molecular structure, which allows them to gently exfoliate the skin’s surface while helping to attract and retain moisture. They help improve the appearance of uneven texture, dullness, and roughness without the intensity often associated with stronger exfoliating acids. Their hydrating and skin-conditioning properties make them a popular choice in formulations designed to promote a smoother, brighter, and more refined-looking complexion, particularly for sensitive or easily reactive skin types.
