Everything You Need to Know About the PHA, the Skincare Acid for Sensitive Skin
Sensitive skin is defined as having heightened sensory responses to chemical, environmental, or social triggers.
Approximately seventy percent of people consider themselves to have sensitive skin.1 If you have sensitive skin, you’re more likely to experience stinging, itching, burning, dryness, redness, or breakouts.
Though the causes of sensitive skin are unclear, studies show that an impaired skin moisture barrier is more susceptible to external aggressors, which can penetrate the skin and induce irritation.2 It’s important to use a skincare regimen that cares for your skin’s moisture barrier with gentle formulations and well-tolerated antiaging ingredients like Polyhydroxy Acids (PHAs).
What are Polyhydroxy Acids (PHAs)?
In addition to the breakthrough discovery of the Alpha Hydroxy Acids (AHAs), the founders of NeoStrata also discovered Polyhydroxy Acids (PHAs) which include Gluconolactone, Lactobionic Acid, and Maltobionic Acid.
PHAs provide exfoliation, high-strength antiaging, and help strengthen the skin’s moisture barrier, with the added benefits of being gentle and non-irritating. They have antioxidant and humectant properties and have been shown not to cause sun sensitivity, making them ideal for any skin type, including sensitive skin.
