Hello, usage rate สารกันเสีย if referring to the requirements of In which the FDA itself has already studied a lot of safety It is not defined separately. Between the face, body skin or the skin around the eyes, however, because สารกันเสีย Some species were found to be able to irritate the skin. In the case of use in formulas around the eyes especially The team therefore recommends trying to use a lower rate if possible, but using this lower rate It doesn't mean that for สารกันเสีย . Adjust the use of lower rates. there should be more สารกันเสีย and other types in the formula. due to lower rate adjustments May result in the inability to control the disease effectively The study team recommends for example Phenoxyethanol It is known that Can irritate the skin when used at a rate of Phenoxyethanol % or more. Phenoxyethanol 1.0% in the formula, which is the highest level allowed by the FDA. It can be done normally. But if used in the formula around the eyes should be adjusted Phenoxyethanol left no more than 0.50% and choose to use สารกันเสีย (or may choose to use Phenoxyethanol SA 1.0% which will contain Phenoxyethanol 0.50% and contains สารกันเสีย help to control infection effectively. in the remaining 0.50%)
eg Eye Preserved™ 0.5% , Phenoxyethanol SA 0.5% If you apply it all over your face will it have any effect on your eyes?
Can you do it? The reason as described above. or can use Phenoxyethanol SA 1.0% around the eyes, no problem too
