MORE ABOUT PHA
What Is PHA?
PHA stands for Poly Hydroxy Acid, a group of acids similar to AHAs and BHAs but with gentler properties. Unlike AHAs (like glycolic acid) and BHAs (like salicylic acid), PHAs have a larger molecular size, meaning they do not exfoliate as deeply. This makes them milder on the skin and particularly suitable for sensitive or hypersensitive skin types.
PHA also acts as an antioxidant and helps to retain moisture in the skin. Examples of PHAs include gluconolactone and lactobionic acid.
Benefits of PHA
PHA has several qualities that make it an excellent choice in skincare:
- Gently exfoliates the skin
- Hydrating properties
- Antioxidant effects
- Helps reduce appearance of fine lines
- Suitable for sensitive skin
Because PHAs are milder than AHAs and BHAs, they can often be used daily in skincare routines. However, it’s always best to start slowly and observe how your skin reacts.
PHA vs. AHA and BHA
PHA, AHA, and BHA are all exfoliating acids but differ in how they work:
- AHAs, like glycolic and lactic acid, provides an effective exfoliation on the skin´s surface. They’re great for dry or mature skin.
- BHAs, like salicylic acid, are oil-soluble and best suited for oily and acne-prone skin as they clean effectivly the pores.
- PHAs are a gentler version of AHAs, making them more suitable for sensitive skin or those who cannot tolerate stronger acids
Can You Use PHA and Retinol Together?
Yes, PHA and retinol can be used together, but it’s important to proceed cautiously and test how your skin tolerates the combination. A good strategy is to use PHA in the morning and retinol in the evening, or to alternate days.
What Should You Not Combine with PHA?
To avoid irritation, you generally shouldn’t combine PHA with other strong acids like glycolic acid or salicylic acid in the same application. If you want to use multiple acids in your routine, try alternating them on different days or applying them at different times of day. Some products are specially formulated to contain multiple acids for optimal results.
Which Products Contain PHA?
There are many products with PHA available on the market, including:
- PHA serums – Great for gentle exfoliation and a radiant glow
- PHA face creams – Hydrating and suitable for sensitive skin
- PHA exfoliators – Improve smoothness without visibly irritating the skin.
PHA products are a great choice if you want effective yet mild exfoliation. They’re also ideal for reducing appearance of fine lines and enhancing skin radiance.
Summary
PHA is a fantastic ingredient for all skin types, but especially for those with sensitive skin. It exfoliates gently, hydrates the skin, and gives a beautiful glow. Compared to glycolic acid, it’s milder but still delivers effective exfoliation over time.
If you want a skincare routine that is gentle yet delivers results, products with PHA acid are a fantastic option.
