Iyini i-POA? Nakhu konke odinga ukukwazi

Uma ubheka ngemuva kwebhodlela lokuhlanza ubuso eliseduze nawekungenzeka ukuthi kunethoni yezithako ezibonakala zijwayelekile - kusuka ku-salicylic kuya ku-glycolic acid, i-glycerin nokunye. Kodwa-ke, esinye sezithako ezingajwayelekile ongahlangabezana nazo ama-PHA, abuye aziwe ngama-polyhydroxy acid. Lesi sithasiselo sokunakekelwa kwesikhumba esimatasa besingaphansi kwe-microscope yama-junkies anakekela isikhumba engxenyeni yesibili ka-2018 nango-2019, yingakho siphendukele kudokotela wesikhumba. Nava Greenfield, MD, Schweiger Dermatology ukuthola kahle ukuthi lesi sithako senzani - futhi nakhu esikutholile.

Iyini i-POA?

I-PHAs i-exfoliating acids, efana ne-AHAs (njenge-glycolic acid) noma i-BHA (njenge-salicylic acid), esusa amangqamuzana esikhumba afile futhi asize ukulungisa isikhumba semikhiqizo ethambisayo. I-PHA ingatholakala ezinkulungwaneni zemikhiqizo yokunakekelwa kwesikhumba, kusukela kwezihlanzayo kuye kwezikhipha ama-exfoliators, izinto zokuthambisa nokunye.

Enzani ama-PHA?

Ngokungafani nama-AHA nama-BHA, “ama-PHA abonakala engacasuki kangako esikhumbeni ngakho asetshenziselwa izinhlobo zesikhumba ezizwela kakhulu,” kusho uDkt. Greenfield. Ngenxa yama-molecule awo amakhulu, awangeni esikhunjeni njengamanye ama-asidi, afaka isandla ekubekezeleleni okungcono. Nokho, kuyaphawuleka ukuthi nakuba “isakhiwo sawo samakhemikhali esiyingqayizivele siwenza abe mnene, angase angasebenzi kahle,” kusho uDkt. Greenfield.

Ubani ongazuza ku-PHA?

Ama-PHA anenzuzo ezinhlobonhlobo zesikhumba, kodwa uDkt. Greenfield uncoma ngokuqinile ukuthi ukhulume nodokotela wakho wesikhumba mayelana nokukhathazeka kwesikhumba ngaphambi kokuwasebenzisa. “Nakuba imikhiqizo ye-PHA ithi iphephile esikhumbeni esine-atopic kanye ne-rosacea, zama njalo ukuhlolwa kwesichibi ngaphambi kokusigcoba ebusweni bakho,” usho kanje. Futhi kuye ngethoni yesikhumba sakho, uzophinde ufune ukuhlola i-PHA kahle, njengoba "amathoni esikhumba amnyama adinga ukunakekelwa okwengeziwe nganoma yiluphi uhlobo lomkhiqizo one-acidic ngoba kungaholela ekukhanyeni kwesikhumba."

Ungayifaka kanjani i-PHA ekunakekeleni isikhumba sakho

Ngokuqondene nendlela yakho ehamba ngayo, uDkt. Greenfield uncoma ukulandela izikhombisi-ndlela ezisebhodleleni. "Amanye ama-moisturizers nsuku zonke aqukethe i-PHA njengesithako esingasetshenziswa nsuku zonke, kanti amanye ahloselwe ukusetshenziswa masonto onke njengama-exfoliators," usho kanje.

Ungayithola kuphi i-PHA

Njengoba ama-PHA ethandwa kakhulu ekunakekelweni kwesikhumba, nawo avame kakhulu emikhiqizweni. Kusuka isixazululo ecwebezelayo ukuze Glow Avocado Melt Maskkubonakala sengathi nsuku zonke kunomkhiqizo omusha we-skincare oqukethe i-PHA. "I-PHA, i-BHA, ne-AHA inganikeza izinzuzo ezimweni ezithile zesikhumba uma isetshenziswe ngendlela efanele nangendlela efanele," kusho uDkt. Greenfield, "kodwa ngiye ngabona iziguli zizama imikhiqizo eziyithenga ku-inthanethi ekhaya futhi zigcina ngokusha okubi kakhulu. izinyanga eziningi. nokwelashwa kobuhle ukuze kuphole,” usho kanje, ngakho-ke kubalulekile ukuthi uzihlole futhi ukhulume nodokotela wakho wesikhumba ngaphambi kokugxumela ekunakekelweni kwesikhumba esine-asidi - noma ngabe kumnene kangakanani.
