Polyhydroxy Acids (PHAs)
The founders of NeoStrata not only pioneered Alpha Hydroxy Acids (AHAs) but also advanced skincare innovation with Polyhydroxy Acids (PHAs). These gentle yet effective exfoliants help improve skin tone, texture, and luminosity, making them a powerful anti-aging ingredient suitable for even the most sensitive skin.
Unlike AHAs, PHAs offer mild exfoliation without irritation, while also strengthening the skin’s moisture barrier. These properties make them an ideal choice for all skin types, including those prone to sensitivity or reactivity.
Key Benefits of PHAs:
- PHAs gently exfoliate the skin without irritation
- PHAs help to enhance the moisture barrier of the skin
- PHAs do not induce sensitivity to sunlight
- PHAs have both antioxidant and moisturising properties
- PHAs are safe for post-procedure care, supporting skin recovery
- PHAs are particularly suitable for individuals with sensitive and reactive skin
Types of PHAs
The most common types of polyhydroxy acids (PHAs) used in skincare are gluconolactone, maltobionic, and lactobionic acid.
Gluconolactone is a naturally occurring compound in the skin that provides anti-aging benefits and gentle exfoliation without increasing sun sensitivity. Ideal for sensitive skin types and those recovering from superficial cosmetic treatments, as it is gentle on the skin. Gluconolactone enhances the skin's moisture barrier, increasing its resilience, while also delivering significant antioxidant benefits.
Lactobionic and Maltobionic Acid, known as "Bionic Acids," are derived from natural sugars. These acids help reduce the appearance of fine lines, wrinkles, discoloration, enlarged pores, and rough skin, promoting a smoother, more even complexion. Their deeply hydrating properties make them especially beneficial for extremely dry, dehydrated, or parched skin types.
Neostrata Restore Range
PHAs are available in a wide range of Neostrata products, including cleansers, toners, moisturisers, and serums. The Restore Collection, specifically formulated for sensitive skin, delivers gentle yet effective anti-aging benefits without irritation. These PHA-rich formulations help nourish, hydrate, and rejuvenate the skin while supporting a healthier, more radiant complexion.
