Pharmaceutically, DL-lactic acid yog siv rau hauv cov tshuaj formulations, tshwj xeeb tshaj yog nyob rau hauv kev tsim cov tshuaj uas tso tawm tas mus li thiab biodegradable polymers rau cov kab ke xa tshuaj. Nws sib xws nrog cov tshuaj compounds thiab biodegradability pab rau nws qhov tseem ceeb hauv kev siv tshuaj. Hauv cov tshuaj pleev ib ce, DL-lactic acid yog siv rau hauv cov khoom siv tawv nqaij rau nws cov khoom exfoliating. Nws pab hauv sloughing tawm cov hlwb tuag tawv nqaij, txhawb kev rov ua dua tshiab ntawm daim tawv nqaij thiab txhim kho cov qauv. DL-lactic acid kuj tseem siv rau hauv cov khoom saib xyuas plaub hau los txhim kho kev noj qab haus huv ntawm lub taub hau thiab tswj cov mob xws li dandruff. Tsis tas li ntawd, DL-lactic acid ua lub luag haujlwm hauv kev ua liaj ua teb ua ib feem ntawm cov chiv thiab cov av conditioners. Nws lub peev xwm los kho cov av pH thiab muab cov as-ham txhawb nqa kev loj hlob ntawm cov nroj tsuag thiab kev loj hlob ntawm cov qoob loo. Qhov xwm txheej zoo rau ib puag ncig ntawm DL-lactic acid ua rau nws yog qhov kev xaiv zoo hauv kev ua liaj ua teb ruaj khov. Kev siv DL-lactic acid hauv kev lag luam suav nrog nws siv ua tus neeg ua ntej hauv kev tsim cov yas biodegradable, coatings, thiab zaj duab xis. Cov ntaub ntawv zoo rau ib puag ncig no muab lwm txoj hauv kev rau cov yas ib txwm muaj, txo qhov cuam tshuam rau ib puag ncig thiab txhawb kev ruaj khov hauv cov txheej txheem tsim khoom. Ntxiv mus, DL-lactic acid yog qhov tseem ceeb hauv kev tshawb fawb thiab chaw kuaj mob rau kev tshawb fawb biochemical thiab kev kuaj mob. Nws qhov muaj nyob hauv kev sim pab hauv kev tshuaj xyuas cov txheej txheem metabolic, kev ua haujlwm enzyme, thiab cov txheej txheem physiological, pab txhawb rau kev nce qib ntawm kev tshawb fawb thiab kev tshawb fawb kho mob. Zuag qhia tag nrho, DL-lactic acid's dual enantiomeric composition muab nws ntau yam kev siv hauv zaub mov, tshuaj, tshuaj pleev ib ce, kev ua liaj ua teb, kev tsim khoom lag luam, thiab kev tshawb fawb. Nws qhov kev hloov pauv thiab cov khoom muaj txiaj ntsig ua rau nws yog ib qho khoom muaj nqis nrog cov ntawv thov xws li kev txhim kho cov saj mus rau kev txhawb nqa kev ruaj khov hauv ntau yam lag luam.
