Vim li cas kev tiv thaiv lub teeb tseem ceeb
Qee cov khoom xyaw nquag degrade thaum raug lub teeb:
Vitamin C (L-ascorbic acid)
Retinoids (retinol, retinaldehyde)
Qee cov nroj tsuag rho tawm (xws li St. John's wort, citrus roj)
Cov roj tsw qab (tuaj yeem oxidize thiab hloov xim / tsw)
Rau cov khoom xyaw no, lub ntim yuav tsum txo qis kev sib kis ntawm lub teeb mus rau qib tau txais.

Dab tsi tseem ceeb?
Amber iav ib leeg uatsis yoglav stability. Cov yam tseem ceeb yog:
Lub teeb kis tus nqi (%)ntawm qhov sib txawv wavelengths - ntsuas, tsis txhob xav.
Secondary ntim- ib lub thawv opaque tuaj yeem tig txhua lub khob iav rau hauv lub thawv uas muaj kev nyab xeeb.
Formula stability- qee qhov "light-sensitive" actives ruaj khov rau lub hlis txawm nyob rau hauv cov iav ntshiab yog tias tsim nyog.
Tus neeg siv tus cwj pwm- yog tias cov khoom zaum ntawm lub txee chav dej ci ntsa iab, amber iav pab. Yog tias khaws cia rau hauv tub rau khoom lossis lub thawv, txhua lub iav ua haujlwm.
