You've probably already heard of fruit acids? They're also called AHAs (but also PHAs and BHAs) and they're now ubiquitous in the world of cosmetics and beauty. But what do these three letters mean, and what's really behind this ingredient?
These acids, known for their exfoliating and hydrating properties, have proven effective in improving skin texture, radiance, and reducing imperfections. In this article, we will explore the beneficial effects of AHAs and PHAs on the skin.
AHAs and PHAs: What are they?
Alpha Hydroxy Acids (AHAs) and Poly Hydroxy Acids (PHAs) are chemical compounds naturally present 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 primarily 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 skin cells from the top layer, allowing for faster cell regeneration. This gentle exfoliation can help reduce blemishes, dark spots, and fine lines, while also 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 particularly beneficial for dry and dehydrated skin. This ability to deeply hydrate helps maintain the skin barrier and prevent excessive flaking, which can leave skin looking 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.
Skin tone evening
Uneven skin tone, 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 reducing discoloration. They work by inhibiting the production of melanin, the pigment responsible for skin color.
Alpha Hydroxy Acids (AHAs) and Poly Hydroxy Acids (PHAs) offer numerous benefits for the skin, including gentle exfoliation, deep hydration, reduced signs of aging, and a more even complexion. These ingredients have become staples in many skincare routines, but it's essential to use them with caution, depending on your skin type and specific needs. Ultimately, AHAs and PHAs are powerful allies for healthy, radiant skin, and regular use can work wonders to improve your skin's texture, luminosity, and youthful appearance.
