PSA About PHAs
You've probably been seeing letters like PHA, AHA, and BHA floating around in the skin-universe, but have you ever done a deep dive into exactly what they mean and why they're included in your skin care?
If your answer no, then you're in the right place because today, we're doing an ingredient spotlight on PHA and why PHA is essential in your skin care.
We've done all the research for you and put everything into laymen's terms, so all you have to do is sit back, look pretty and enjoy this read.
What Are PHA's?
Perhaps the biggest question on your mind is what exactly does PHA stand for? Well, it's relatively simple. PHA is the acronym used for Polyhydroxy Acids. PHA's are a group of acids used in skin care products as ingredients to exfoliate the skin chemically.
While they fall under the AHA family, PHAs are larger than AHAs like glycolic acid or lactic acid. The most common types of PHAs you will find in your skin care products are:
- Gluconolactone Acid
- Galactose Acid
- Lactobionic Acid
Because of their larger molecular size, PHAs tend to do the trick on the surface of your skin. They are gentle on the skin when they take a bit longer than their AHA family to sink into your skin properly.
The main benefit of PHA's in your skin care is to buff away dead skin cells gently. This action results in repairing skin and reducing skin damage by making the skin texture and tone look more even and smooth.
What Skin Types Are PHAs Best Suited For?
PHA's are immaculate for sensitive skin types (i.e. skin prone to redness and irritation) in how they are typically non-irritating because of their larger molecular size. While this may be true for most, everyone's skin is different, and you may want to prepare for some discomfort if it's your first time using PHA.
PHAs are also humectants, which means they draw and lock-in water moisture—something for all you dry skin folks out there to consider. One of the neatest things about PHAs I found while researching the ingredient is that they are great in anti-inflammatory and antioxidant properties.
If you're experiencing typical signs of aging but would still like to tend to these signs, PHA's are excellent for combating glycation, which is a process where your skin's collagen and elastin start to weaken.
Are There Any Side Effects Associated With Using PHAs?
The whole point of using PHAs in skin care is because they have little-to-no side effects. Instead of working deep within the skin, they keep your surface layers supple and bright. But because PHAs are still within the acids family, a patch test is always a good idea before going straight onto more sensitive areas of your face!
How To Use PHAs
The best way to use PHAs is through products that have to stay on your skin for a prolonged period. This time frame allows PHAs to sink into your skin and work more efficiently and slowly. Because they are chemical exfoliants, you can find PHAs in liquid exfoliants, toners, masks, and moisturizers.
You can also use PHAs in combination with other acids and plenty of other treatments! For example, you can combine PHAs with retinoids to combat acne.
