Polyhydroxy acids (PHAs) are making waves in the skincare world as a gentle yet effective alternative to other chemical exfoliants. These skin-loving ingredients offer many benefits, especially if you have sensitive skin or are new to chemical exfoliation.
In this guide, we’ll explore PHAs, how they work, and the best ways to incorporate them into your skincare routine. Whether you’re a skincare novice or a seasoned enthusiast looking for a gentler exfoliation option, this article has you covered.
Let’s jump in and see what PHAs can do for your skin!
Polyhydroxy acids (PHAs) are a type of chemical exfoliant that belongs to the same family as alpha-hydroxy acids (AHAs) and beta-hydroxy acids (BHAs). However, PHAs have a larger molecular structure and penetrate the skin more slowly and gently.
The most common types of PHAs used in skincare are:
– Gluconolactone
– Lactobionic acid
– Galactose
These gentle exfoliants help remove dead skin cells and provide hydration and antioxidant benefits, making PHAs particularly suitable for sensitive, dry, or mature skin and individuals with conditions like rosacea or eczema.
How Do Polyhydroxy Acids (PHAs) Work?
PHAs work by breaking down the bonds between dead skin cells on the surface. This process, known as chemical exfoliation, helps reveal fresher, brighter skin underneath.
Unlike AHAs and BHAs, which can sometimes irritate due to their deeper penetration, PHAs work more gradually and gently.
Their larger molecular structure means they don’t penetrate as deeply, reducing the risk of irritation while still providing effective exfoliation.
Moreover, PHAs have humectant properties, which can attract and retain moisture in the skin. This dual action of exfoliation and hydration makes PHAs a unique and valuable ingredient in skincare.
Key Benefits of Polyhydroxy Acids (PHAs)
Polyhydroxy acids offer a range of benefits that make them a valuable addition to any skincare routine. Here are some of the key advantages:
Gentle Exfoliation
PHAs provide effective yet mild exfoliation by gradually removing dead skin cells, making them suitable for sensitive skin without irritation.
Hydration
As humectants, PHAs attract moisture to the skin, helping to maintain hydration levels and keep the skin feeling plump and soft.
Strengthening Skin Barrier
PHAs enhance the skin’s barrier function, improving its resilience against environmental stressors and preventing moisture loss.
Antioxidant Properties
With antioxidant capabilities, PHAs protect the skin from free radical damage caused by pollution and UV exposure, promoting overall skin health.
Anti-Aging Benefits
PHAs support cell turnover and improve skin texture, reducing the appearance of fine lines and contributing to a youthful look.
Even Skin Tone
They help fade hyperpigmentation and dark spots, promoting a more even and radiant complexion over time.
Compatibility with Sensitive Skin
PHAs are gentle enough for sensitive skin types, making them an excellent option for those prone to irritation.
Common Uses of PHAs in Skin Care
Polyhydroxy acids play essential roles in skin care products and are commonly utilized for the following purposes:
– Cleansers
– Toners
– Serums
– Moisturizers
– Face masks
– Eye creams
The concentration of PHAs in these products varies, typically ranging from 3% to 15%.
Possible Side Effects and Considerations
While PHAs are generally well-tolerated, it’s still important to be mindful of potential side effects:
Mild Irritation
While PHAs are generally gentle, some individuals may experience slight irritation, especially when first introduced to their routine. If redness or discomfort occurs, try reducing the frequency of use or switching to a lower concentration.
Sun Sensitivity
Like other exfoliants, PHAs can increase sun sensitivity. It’s essential to apply broad-spectrum sunscreen daily when using PHAs to protect your skin from UV damage.
Interaction with Other Products
When using PHAs in combination with other active ingredients like retinoids or vitamin C, be cautious to avoid irritation. It’s best to introduce these products gradually or alternate their use.
How to Incorporate PHAs into Your Skin Care Routine
Adding PHAs to your skincare routine can be a gentle way to boost your skin’s glow and overall health. Here are some tips for incorporating PHAs:
Start Slowly
Use PHA products 2-3 times a week and gradually increase frequency as your skin adjusts.
Choose the Right Product
Choose a PHA product, such as a cleanser, toner, serum, or moisturizer, that aligns with your skin type and concerns.
Layer Properly
If using a PHA serum, apply it after cleansing and before moisturizing. For leave-on products, wait a few minutes before applying your following product to allow the PHA to absorb.
Combine Wisely
PHAs can be used alongside other skincare ingredients, including vitamins C and E, peptides, and hyaluronic acid.
Use Sun Protection
Always apply broad-spectrum sunscreen during the day when using PHAs (and for healthy skin in general!).
Listen to Your Skin
Pay attention to how your skin responds and adjust your routine as needed.
