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.
Bumpy skin is actually called keratosis pilaris, and it is a common—and harmless—skin condition that is most typically found on the upper arms and thighs. Bumpy skin is caused by the buildup of keratin proteins which plug hair follicles, thus resulting in tiny bumps and often rough, dry skin. Usually, this condition begins in childhood and often dissipates with age.
Sometimes bumpy skin are caused by clogged pores that are deep under your skin.
Jojoba oil and rose hip oil are good for improving sebum texture and keeping in moisture for healthier skin. Ingredients that help exfoliate dead skin cells and increase new skin cell production, such as Vitamin A/Retinol, glycolic acid, and salicylic acid, are good for keeping skin smooth as well.
PHA may be effective for bumpy skin, 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.
