Polyhydroxy acids (PHAs) are the new and improved cousins of alpha hydroxy acids (AHAs). They work as chemical exfoliants, and are therefore useful in skincare. They work slowly, which makes them fairly mild. People with sensitive skin can use PHAs without any problem.
PHAs remove dead skin cells from the uppermost layers of skin to reveal soft, bright skin. If you have dull, tired-looking skin, PHAs are the right ingredient for you. They also have antioxidants that protect the skin from UV damage, and make the skin’s barrier stronger. PHA protects collagen from breaking down, which keeps your skin looking younger for longer.
They are mild, so they work slowly – which may not be what you want. PHAs are exfoliants, so be careful when you start using them, especially if your skin is sensitive or damaged. Skin that reacts to new products may find PHAs irritating, mild as they are. Pregnant and breastfeeding women, and people with skin infections or open wounds should avoid using PHAs.
Wrinkles are creases and folds that form in our skin, usually most prominent in our face, neck and hands. Wrinkles are caused by the natural process of aging on our skin, though there are a few circumstances that increase the appearance and depth of wrinkles. Exposure to sun, pollution, and cigarette smoke increase the rate of wrinkling. Genetics also plays a role in the skin’s elasticity, plumpness, and the age at which wrinkles begin appearing.
To prevent wrinkles, it’s best to moisturize daily and wear sunscreen. Additionally, antioxidants protect the skin from free radicals that damage cells and speed up aging. Ingredients and nutrients like rosehip oil, alpha-lipoic acid, herbal extracts, retinol, coenzyme Q10, alpha-hydroxy acids, etc are all beneficial for preventing and reducing wrinkles.
PHA may be effective for wrinkles, but there are many other factors that may affect whether this ingredient would work on your skin or if there are better ingredients that may work for you. Take this skin quiz to find the best ingredients for your skin and build your skincare routine.
