Please allow me to comment as far as I have asked the team. - From this formula, there is no water as a destroyer that can be dissolved in water -
Safe-B3 ™ (
Vitamin B3 10% and
Niacinamide , Switzerland 4% is the same substance. Just produce from different countries. Selecting only one is enough. And choose to use only 5% is enough to use for acne results. And nourish the skin -
Phospholipid must be whole water. and oil in the recipe to be able to mix it -
Vitamin C (L-ascorbic acid) (Fine) 15% and
Vitamin C (L-ascorbic acid) (Fine) 15% thinks one is Ultra-Fine Yes, I think choosing one is enough because it is
Vitamin C same pure The difference is in particle size -
Vitamin C (L-ascorbic acid) with
Ascorbyl Glucoside (AA-2G
stabilized vitamin c ) I think that it should not be in the same formula because It's in the formula that the PH value is different
Vitamin C (L-ascorbic acid) must be in the formula where the value pH is between 2.0-4.0 and
Ascorbyl Glucoside (AA-2G
stabilized vitamin c ), the formula must have a pH in the range of 6.5-6.8. PH value set
Vitamin C will deteriorate - from the formula used
Vitamin C but not in formula
Disodium EDTA to capture charge in water and not yet
Protec™ OX and
Protec™ UV in the formula to prevent
Vitamin C deteriorated - from the formula used
Vitamin C but no oil to dissolve
Protec™ OX and
Protec™ UV and still don't have
Emulsifier for oil and water component - "
Vitamin C type
L-ascorbic acid should not be directly mixed with water. due to oxidation and deterioration (To mix with water directly Should be used within 3 days) used in cosmetics. If water is included, it should be added
Ferulic Acid and
Vitamin E to reduce oxidation (adding
Ferulic Acid and
Vitamin E to reduce oxidation is copyright of SkinCeuticals Please click to see how) or add
Glutathione (L-Reduced type) to reduce oxidation causing
L-ascorbic acid does not lose quality" is the method of use.
Vitamin C type
L-ascorbic acid to be the most effective. - From the formulas are used both
Vitamin C and
Niacinamide cannot be mixed. Both can be in the same formula. because it will affect the stability of
Vitamin C but you can separate the formulas and use them together. Thank you very much.
