You have probably already heard about fruit acids? They are also called AHA (as well as PHA and BHA) and are now omnipresent in the world of cosmetics and beauty. But what do these 3 letters mean, and what really lies behind this ingredient?
These acids, known for their exfoliating and moisturizing properties, have proven effective in improving skin texture, brightness, and reducing imperfections. In this article, we will explore the beneficial action of AHA and PHA on the skin.
AHA and PHA: What Are They?
Alpha Hydroxy Acids (AHA) and Poly Hydroxy Acids (PHA) are chemical compounds naturally found in certain fruits and dairy products. The most commonly used AHAs in cosmetics are glycolic acid, lactic acid, malic acid, and citric acid, while PHAs include acids such as gluconolactone and lactobionate. These acids are used especially for their exfoliating, moisturizing, and anti-aging properties.
Gentle Exfoliation
One of the main benefits of AHAs and PHAs is their ability to gently exfoliate the skin. They work by removing dead cells from the skin’s surface, allowing for faster cell regeneration. This gentle exfoliation can help reduce imperfections, brown spots, and fine lines, while improving skin texture.
Deep Hydration
Unlike some other types of exfoliating acids, such as BHAs (Beta Hydroxy Acids), AHAs and PHAs also have moisturizing properties. They attract moisture into the skin, which is especially beneficial for dry and dehydrated skin. This ability to deeply hydrate helps maintain the skin barrier and prevent excessive flaking, which can make the skin look dull.
Reduction of Signs of Aging
AHAs and PHAs are often used in anti-aging products because of their ability to stimulate collagen production. Collagen is an essential protein that maintains skin firmness and elasticity. By promoting collagen synthesis, AHAs and PHAs help reduce the appearance of wrinkles and fine lines, making them valuable allies in the fight against skin aging.
Evening Out Skin Tone
An uneven complexion, with brown spots or uneven pigmentation, can be a common skin concern. AHAs and PHAs can help even out skin tone by lightening brown spots and fading discolorations. They work by inhibiting melanin production, the pigment responsible for skin coloration.
Alpha Hydroxy Acids (AHA) and Poly Hydroxy Acids (PHA) offer many benefits for the skin, including gentle exfoliation, deep hydration, reduction of signs of aging, and evening out skin tone. These ingredients have become staples in many skincare routines, but it is essential to use them carefully, according to your skin type and specific needs. Ultimately, AHA and PHA are powerful allies for healthy, radiant skin, and their regular use can work wonders to improve your skin’s texture, brightness, and youthfulness.
