Hello, 1. The formula is using Perfect-C and Sym-White Sodium Metabisulfite can help with white skin Sodium Metabisulfite 0.15% to reduce the chance of discoloration. Sym-White 3. It is recommended to use Mild Preserved Eco 1% instead is much more gentle on the skin.

1. What is your opinion of the staff if you reduce perfect c ? perfect c down from 5% to 3% by how much whiteness change? or Sodium Metabisulfite no difference Sodium Metabisulfite To reduce the chance of changing color, right? If not serious about the color change But not wearing it doesn't mean that the extract will deteriorate quickly, right? 2.1 The color change. SymWhite that mean the deterioration of the extract? Or just change the color only 3. Using Phenoxyethanol 1% have Chances of irritation But it does not adversely affect the formula or reduce the quality of the extract, right? Thank you.

Hello, 1. No test data here, sorry 2. Sodium Metabisulfite can't prevent color change in every formula. You must also look at the ingredients in the recipe. And which ones can cause discoloration? In general, Sodium Metabisulfite will be used with Alpha Arbutin , Sym-White and Activated Resorcinol but for other substances There is no clear test result that can help reduce the chance of discoloration 2.1 Deterioration 3. Yes.
