For years, skincare conversations around exfoliation have focused on alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). While these ingredients remain popular, many consumers are now searching for exfoliating products that deliver smoother, brighter-looking skin without the irritation often associated with stronger acids.
This shift has led to growing interest in polyhydroxy acids, commonly known as PHAs. PHAs offer many of the same skin-refining benefits associated with traditional exfoliating acids while providing a gentler experience, making them an appealing option for sensitive, dry, or reactive skin types. As more consumers prioritize barrier support and skin comfort, PHAs are becoming an increasingly attractive category for private label skincare brands.
What Are PHAs?
Polyhydroxy acids are a class of chemical exfoliants that help remove dead skin cells from the skin's surface. Common PHAs include gluconolactone and lactobionic acid.
Like AHAs, PHAs work by encouraging the shedding of dull, dead skin cells that can contribute to rough texture and uneven-looking skin. However, PHAs have a larger molecular structure than AHAs, which means they penetrate the skin more slowly and are generally associated with a gentler exfoliation experience.
Because of this, PHAs are often recommended for consumers who find glycolic acid or other stronger exfoliating acids too aggressive for regular use.
For more information on PHAs, review our ingredient glossary entry here.
Why Consumers Are Turning to PHAs
Today's skincare consumer is increasingly focused on maintaining a healthy skin barrier. Rather than pursuing aggressive exfoliation, many shoppers are seeking products that support smoother-looking skin while minimizing the potential for irritation.
PHAs align well with this trend because they can help:
-
Improve the appearance of skin texture
-
Promote a brighter-looking complexion
-
Support smoother-feeling skin
-
Gently remove surface buildup
-
Complement barrier-focused skincare routines
-
Fit into daily-use exfoliation regimens
This combination of effectiveness and gentleness has made PHAs particularly appealing to consumers with sensitive, dry, mature, or easily irritated skin.
PHAs vs AHAs: What's the Difference?
While both PHAs and AHAs exfoliate the skin's surface, they differ in how they interact with the skin.
AHAs
Common examples include glycolic acid and lactic acid.
AHAs are often chosen for:
-
Visible skin renewal
-
Brightening benefits
-
Addressing rough texture
-
Improving the appearance of fine lines
However, some consumers may experience redness, dryness, or sensitivity when using stronger AHAs.
PHAs
Common examples include gluconolactone and lactobionic acid.
PHAs are often chosen for:
-
Gentle exfoliation
-
Sensitive skin routines
-
Daily-use formulations
-
Barrier-conscious skincare regimens
-
Consumers new to exfoliating acids
For brands looking to serve consumers who want exfoliation without the intensity often associated with stronger acids, PHAs provide an attractive alternative.
Why PHAs Are a Strong Private Label Opportunity
The skincare industry has seen a growing movement toward skin barrier support, microbiome-friendly products, and gentle active ingredients. Consumers are becoming more educated about over-exfoliation and are increasingly searching for products that help maintain balance while still delivering visible results.
This creates an opportunity for brands to position PHA products around:
-
Sensitive skin care
-
Daily exfoliation
-
Skin barrier support
-
Gentle skin renewal
-
Beginner-friendly active skincare
-
Hydration-focused exfoliation
Because PHAs appeal to multiple consumer segments, they can fit into a variety of brand concepts, from clean beauty and sensitive skin collections to professional skincare and dermatologist-inspired lines.
