Microneedlingtau txais koob meej hauv kev kho mob zoo nkauj thiab kev xa tshuaj vim nws qhov cuam tshuam me me, tsis mob, thiab muaj txiaj ntsig zoo. Txawm li cas los xij, qhov no tsis tau txhais hais tias nws yog qhov tsis muaj qhov tsis zoo, pheej hmoo - cov txheej txheem pub dawb. Txhua txoj kev uas nkag mus rau ntawm daim tawv nqaij barrier, txawm li cas los xij, yuav muaj qee yam kev mob tshwm sim. Kev nkag siab zoo ntawm cov kev mob tshwm sim no thiab lawv cov txheej txheem hauv qab yog qhov tseem ceeb rau ob tus kws tshaj lij kev lag luam thiab cov neeg siv khoom los txiav txim siab paub.

Qhov tshwm sim feem ntau tom qab microneedling yog cov tshuaj tiv thaiv ntawm daim tawv nqaij. Txij li thaum microneedling tsim ntau ntau mus rau pua pua ntawm cov kab mob microscopic nyob rau hauv stratum corneum, daim tawv nqaij pib mob inflammatory teb raws li kev tiv thaiv mechanism. Cov tsos mob xws li erythema, me me o, thiab kub hnyiab tau tshwm sim tam sim ntawd tom qab kev kho mob, zoo li lub hnub ci me me. Cov tsos mob no feem ntau tshwm sim li ntawm 30 feeb mus rau 2 teev tom qab qhov txheej txheem thiab maj mam txo qis. Rau cov qauv tshuaj pleev ib ce microneedling nrog rab koob ntev ntawm 200 thiab 500 micrometers, erythema feem ntau daws tag nrho hauv 24 mus rau 48 teev. Txawm li cas los xij, thaum kev kho mob tob zuj zus siv cov cuab yeej siv nrog rab koob ntev tshaj 500 micrometers, erythema yuav nyob ntev txog 3 mus rau 5 hnub.

Txawm hais tias qhov mob thiab qhov tsis xis nyob yog mob me dua li kev txhaj tshuaj ib txwm muaj, lawv tsis tas li. Thaum lub sij hawm microneedling, qee cov neeg mob tseem yuav hnov ​​​​me ntsis stinging los yog tingling, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas nyias nyias xws li ib ncig ntawm lub qhov muag thiab daim di ncauj. Rau cov tib neeg uas muaj qhov mob qis dua, qhov tsis xis nyob no yuav qhia tau ntau dua. Tsis tas li ntawd, hom microneedle ntaus ntawv tuaj yeem cuam tshuam rau theem ntawm kev tsis xis nyob - hluav taws xob microneedle cwjmem feem ntau muaj kev vibration ntau dua thiab feem ntau xis dua li cov khoom siv ntawm phau ntawv; hollow microneedles, uas yuav tsum tau txhaj tshuaj, tej zaum yuav ua rau ntxiv siab los yog o- mob ntsig txog.

Hyperpigmentation yog lwm yam kev mob tshwm sim tsim nyog sau cia. Hauv cov tib neeg uas muaj cov tawv nqaij tawv tawv (Fitzpatrick hom IV txog VI), microneedling tuaj yeem ua rau muaj qhov tshwm sim ntawm cov kab mob inflammatory hyperpigmentation. Qhov no tshwm sim vim hais tias cov microtrauma induced los ntawm microneedling activates melanocytes, ua rau ntau lub zos pigment deposition. Cov ntaub ntawv qhia tau hais tias qhov tshwm sim ntawm post-microneedling hyperpigmentation nyob rau hauv cov neeg Esxias yog kwv yees li 2% mus rau 5%, feem ntau cuam tshuam nrog kev kho mob ntau dhau, xaiv ntev koob tsis tsim nyog, lossis kev tiv thaiv hnub tsis txaus tom qab kho. Nyob rau hauv sib piv, hypopigmentation kuj tsis tshua muaj, tab sis qee zaus pom nyob rau hauv cov cheeb tsam raug rov kho dua.

Txawm hais tias muaj kev pheej hmoo ntawm kev kis tus kab mob tsawg, nws muaj. Microneedling cuam tshuam cov tawv nqaij barrier, theoretically tsim ib qho chaw nkag rau cov kab mob. Yog tias cov txheej txheem tau ua nyob rau hauv qhov chaw tsis muaj menyuam tsis muaj menyuam, cov cuab yeej siv tsis tau zoo, lossis tom qab- kev kho mob tsis tsim nyog,Staphylococcus aureuslos yogPropionibacterium pob txuvNws tuaj yeem cuam tshuam, ua rau folliculitis, pustules, lossis txawm tias cellulitis. Ib txoj kev tshawb nrhiav rov qab tau qhia tias tus kab mob kis tau tom qab microneedling ntawm cov tsev kho mob tau lees paub tsawg dua 0.1%, thaum nyob rau hauv cov tsev kho kom zoo nkauj lossis tus kheej - kev kho mob hauv tsev, tus nqi tuaj yeem nce mus rau 1%–3%.

Kev tsis haum tshuaj kuj yog ib hom kev mob tshwm sim uas tsis tuaj yeem pom. Microneedling feem ntau ua ke nrog cov khoom xyaw ua haujlwm xws li vitamin C, hyaluronic acid, thiab botulinum toxin. Cov microchannels tsim los ntawm microneedling tau txhim kho qhov kev nqus ntawm cov tshuaj no, tab sis lawv kuj ua rau muaj kev pheej hmoo ntawm kev ua xua. Rau cov neeg mob paub tias ua xua rau qee yam khoom, microneedling tus me nyuam tuaj yeem ua rau mob hnyav dua li kev siv tshuaj pleev ib ce.

Kev nkag siab txog cov txheej txheem tom qab cov kev mob tshwm sim no tsis yog tsim los ua kom muaj nuj nqis ntawm microneedling, tab sis yog tsim kom muaj lub hauv paus kev tshawb fawb rau kev tswj hwm kev pheej hmoo. Tsuas yog nrog kev pom zoo tag nrho tuaj yeem ua ob tus kws kho mob thiab cov neeg mob sib koom ua ke txhim kho txoj kev kho kom zoo.
