Munyika yeskincare, niacinamide yakafanana nemumhanyi-akatenderedza, achikunda moyo yevasingaverengeki vanoda runako nemaitiro ayo akawanda. Nhasi, ngatiburitse chifukidziro chisinganzwisisike cheiyi "nyeredzi yeganda" uye tiongorore zvakavanzika zvayo zvesainzi uye mashandisiro anoshanda pamwechete.
1, Scientific decoding ye nicotinamide
Niacinamideimhando yevhitamini B3, kemikari inozivikanwa se pyridine-3-carboxamide. Chimiro chayo chemolecular ine pyridine mhete uye boka reamide, iro rinoiisa nekugadzikana kwakanakisa uye biological chiitiko.
Iyo nzira yekuita muganda inonyanya kusanganisira inhibiting melanin kutamiswa, kuwedzera ganda barriers basa, uye kudzora sebum secretion. Tsvagiridzo yakaratidza kuti nicotinamide inogona kuwedzera zvakanyanya kuumbwa kweceramides uye mafuta acids, ichiwedzera kutendeseka kweiyo stratum corneum.
Iyo bioavailability ndiyo kiyi yekushanda kwe nicotinamide. Iine huremu hudiki hwema molecular (122.12 g / mol), kunyungudika kwemvura kwakasimba, uye inogona kunyatsopinda mukati mepidermis. Data yekuyedza inoratidza kuti bioavailability yetopical nicotinamide inogona kusvika pamusoro pe60%.
2. Iyo yakawanda mhedzisiro ye nicotinamide
Mumunda wekuchena, nicotinamide inowana yunifomu yeganda toni nekudzivisa kuendeswa kwe melanosomes kune keratinocytes. Miedzo yemakiriniki yakaratidza kuti mushure mekushandisa chigadzirwa chine 5% niacinamide kwemavhiki masere, nzvimbo yepigmentation yakadzikira ne35%.
Kudzora mafuta uye kubvisa acne, niacinamide inogona kudzora sebaceous gland basa uye kuderedza sebum secretion. Tsvagiridzo yakasimbisa kuti mushure mekushandisa zvigadzirwa zvine 2% niacinamide kwemavhiki mana, sebum secretion inoderera ne25% uye huwandu hwemapundu hunodzikira ne40%.
Panyaya yekurwisa-kuchembera, niacinamide inogona kukurudzira collagen synthesis uye kunatsiridza elasticity yeganda. Ongororo dzakaratidza kuti kushandisa chigadzirwa chine 5% niacinamide kwemavhiki gumi nemaviri kunoderedza mitsetse yeganda ne20% uye inowedzera elasticity ne30%.
Kugadzirisa basa rekuvharira ndeimwe mukana wakakura weniacinamide. Inogona kukurudzira kuumbwa kweceramide uye kuwedzera kugona kweganda kuchengetedza mvura. Mushure mekushandisa chigadzirwa chine 5% niacinamide kwemavhiki maviri, iyo transdermal mwando kurasikirwa kweganda kwakadzikira ne40%.
3, Iko kushandiswa kwe nicotinamide kunoshanda
Paunenge uchisarudza zvigadzirwa zvine niacinamide, kutarisisa kunofanirwa kubhadharwa kune yekumisikidza uye fomula. 2% -5% inzvimbo yakachengeteka uye inoshanda, uye kunyanya kuisa pfungwa kunogona kukonzera kutsamwa. Inokurudzirwa kutanga nekudzika kwakadzika uye zvishoma nezvishoma kumisa kushivirira.
Mazano ekushandisa anosanganisira: kushandisa mangwanani uye manheru, kubatanidza ne antioxidants (yakadai sevhitamini C), uye kuteerera kuchengetedzwa kwezuva. Tsvagiridzo yakaratidza kuti musanganiswa we niacinamide uye vhitamini C unogona kuburitsa synergistic mhedzisiro.
Chenjero: Kushatirwa kudiki kunogona kuitika panguva yekushandiswa kwekutanga, zvinokurudzirwa kuita bvunzo dzemunharaunda kutanga. Regedza kushandisa zvigadzirwa zvine acidity yakawandisa kuderedza kugadzikana kweniacinamide.
Kuwanikwa uye kushandiswa kwe nicotinamide kwakaunza shanduko kumunda we skincare. Kubva pakucheneruka uye kupenya kwemavara kusvika pakudzora oiri uye kudzivirira mburwa, kubva pakurwisa kuchembera kusvika pakugadzirisa zvipingamupinyi, izvi zvinosanganisa zvinhu zvakawanda zviri kushandura nzira yatinotarisira nayo ganda redu. Kuburikidza nekunzwisisa kwesainzi uye kushandisa kwakaringana, tinogona kushandisa zvizere kushanda kwe niacinamide kuwana ganda rine hutano uye rakanaka. Ngatirambei tichiongorora zvakavanzika zve skincare uye tirambe tichifambira mberi munzira yekutevera runako.
