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.
A red tint to the skin can be caused by a myriad of situations. Some redness, such as that caused by rosacea, is caused a genetic disorder that affects the blood vessels at the surface of the skin. Other genetic conditions include psoriasis, which also causes redness. Some redness is caused by inflammation due to acne, blemishes, or eczema. Seborrheic dermatitis can also cause redness in the face. Minor irritations or skin allergies will also cause your face to appear red, so it is important to work with a dermatologist to determine the cause of redness on your skin.
There are a few ingredients that can help reduce inflammation associated with redness. For example, rosehip oil, jojoba oil, hemp seed oil, red tea are good for reducing inflammation associated with certain conditions that cause redness. However, it is important to work with a dermatologist to determine the cause of redness on your skin to determine the right course of treatment.
