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.
Hormonal acne is acne which develops in response to hormonal changes, especially a rise in androgens, such as testosterone. The rise in androgen levels can trigger a process of higher sebum production, changes in skin cell activity, inflammation, and colonization of bacteria, resulting in acne.
The secret to winning the battle against hormonal acne is having the right regimen for your skin. Products that are too strong can be irritating and drying, causing your skin to overproduce oil, which leads to more acne. Picking the wrong active ingredients may have no effect on hormonal acne. Using the right regimen for your acne type and skin tolerance can effectively clear acne while keeping your skin healthy and balanced.
PHA may be effective for hormonal acne, 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.
