Safety of PHA
Even very sensitive skin types can tolerate PHAs, including atopic and rosacea skin.
It is thought that the gentle, nonirritating action of PHAs may be partially related to
a larger molecular composition than that of conventional AHAs.
Larger molecules are believed to penetrate the skin at a slower rate, causing less irritation.
This reduced irritation, coupled with natural antioxidant properties,
gives PHAs a gentle, competitive edge over other anti-aging treatments.
PHA는 아토피 .주사 등의 피부에도 사용할수 있는 순한 성분이다
PHA는 입자가 크기 때문에
기존의 AHA보다 순하고 피부에 자극이 적다
What is PHA( Exfoliant , Antioxidants)
PHA는 각질제거제 항산화제이다
Polyhydroxy acids are ingredients such as gluconolactone and lactobionic acid.
They’re supposed to be as effective as AHAs, but less sensitizing.
PHA는 글루코락톤 또는 락토바이오닉 산을 말하는데
이 성분들은 기존의 AHA와 효능은 비슷하지만
Gluconolactone and lactobionic acid are chemically and functionally similar to AHAs (such as glycolic acid).
The significant difference between them and AHAs is that gluconolactone and lactobionic acid have larger molecular structures,
기존의 AHA와 가장큰차이는 큰입자 크기이다
which limits their ability to penetrate the skin,
resulting in less potential for sensitizing side-effects.
입자가 크기때문에 피부를 뚫고 들어가지 못하기 때문에 피부에 자극이 적고 부작용이 적다
Supposedly, this reduced absorption into the skin does not hamper their effectiveness.
Does that mean gluconolactone and lactobionic acid are better for your skin than AHAs in the form of glycolic acid or lactic acid?
According to an Internet-published class lecture by Dr. Mark G. Rubin, a board-certified dermatologist and assistant clinical professor of dermatology at the University of California, San Diego, research on gluconolactone demonstrated only a “6% decrease in dermal penetration” in comparison to glycolic acid, which “isn’t a dramatic improvement.”
Gluconolactone may be slightly less sensitizing for some skin types,
but this isn’t the magic bullet for exfoliation some cosmetics companies have been extolling.
Polyhydroxy acids can also function as antioxidants and may promote some amount of improvement in skin’s surface strength
• PHAs have been found to be compatible with clinically sensitive skin, including rosacea and atopic dermatitis, and can be used after cosmetic procedures.
•PHAs provide additional humectant and moisturization properties compared with AHAs and can enhance stratum corneumbarrier function, therefore increasing the skin's resistance to chemical challenge.
• Most PHAs also possess antioxidant properties.
• PHAs such as gluconolactone or lactobionic acid may be used in combination with other products, ingredients, or procedures such as laser and microdermabrasion to provide additional benefits to therapy or to enhance the therapeutic effect.
•Several studies were conducted in support of this, and methods and results are discussed. In summary, PHA-containing products were used in combination with retinoic acid in treating adult facial acne and were found to be well tolerated.
•PHAs plus retinylacetate (pro-vitamin A) in a cream base exhibited significant antiaging skin benefits such as skin smoothing and plumping.
•PHAs plus hydroquinone showed excellent improvement in antiaging and skin lightening parameters.
• Finally, PHA-containing products were shown to be compatible with African American, Caucasian, and Hispanic/Asian skin and provided significant improvements in photoaging in these populations.
