What is Sensitive Skin?
‘Sensitive skin’ is a common skin-type term that gets thrown around frequently, but what exactly does it mean? Sensitive skin is defined as having heightened sensory responses to chemical, environmental or even social triggers. Approximately 70% of the population 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 still 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 lets you care for your skin’s moisture barrier with gentle formulations and well-tolerated antiaging ingredients like Polyhydroxy Acids (PHAs).
What Are Polyhydroxy Acids (PHAs) and What are the Benefits for your Skin?
In addition to the breakthrough discovery of the Alpha Hydroxy Acids (AHAs), the founders of NeoStrata discovered the next generation of skincare acids, Polyhydroxy Acids (PHAs), that help to improve your skin’s tone, texture and overall radiance. Polyhydroxy Acids are considered an all-star antiaging ingredient for sensitive skin. Unlike AHAs, PHAs are gentle, non-irritating and help to strengthen the skin’s moisture barrier making them ideal for any skin type, including sensitive or reactive skin types. Some of the main benefits of Polyhydroxy Acid include:
PHAs provide gentle exfoliation.
PHAs help strengthen skin’s moisture barrier.
PHAs do not cause sun sensitivity.
PHAs have antioxidant and humectant properties.
PHAs can be used post-procedure.
PHAs are ideal for sensitive and reactive skin types.
What are the top Polyhydroxy Acids (PHAs) To Use in a Skincare Routine?
Gluconolactone: Gluconolcatone is found naturally in the skin and provides antiaging and gentle exfoliating benefits without sun sensitivity. Sensitive skin types, as well as those who have had recent superficial cosmetic procedures, will find comfort in this molecule’s gentle nature. Gluconolactone strengthens the skin’s moisture barrier leaving it more resilient, while also providing potent antioxidant benefits.
Lactobionic & Maltobionic Acid: Also known as "Bionic Acids" are derived from natural sugars. They help to reduce the appearance of lines and wrinkles, discoloration, enlarged pores and roughness through gentle exfoliation. The bionics are a key choice for very dehydrated, parched and dry skin types.
How to Incorporate PHAs into Your Skincare Routine
Thankfully, PHAs are included in a wide array of products from cleansers and toners, to moisturizers, serums and treatments. Developed specifically for sensitive complexions, the Restore Collection features gentle yet effective PHAs for full-strength antiaging benefits without irritation. Nourish your sensitive skin with these skin-loving PHA formulations.

What are the benefits of using PHA in skincare?
PHAs provide gentle exfoliation, help strengthen skin’s moisture barrier, have antioxidant and humectant properties, can be used post-procedure, do not cause any sun sensitivity and are ideal for use on sensitive and reactive skin types.
Can PHA be used on sensitive skin?

How often should I use PHAs in my skincare routine?

Can PHAs be used with other exfoliants like AHAs and BHAs?

Are PHAs suitable for all skin types?
In general, PHAs are well tolerated by all skin types, particularly those with sensitive or reactive skin.
