Hello,
I have made a water base serum with vitamin c brought from aromatic. I was surprised to find that the end product had a PH of 9.2 and I needed to bring it down to 6.5-7 as recommended using a solution of 70% DW and 30% citric acid powder also purchased from here. I worry that the amount needed to get to the correct PH may have an adverse impact on my skin and wondered if my findings are normal, I also wondered why you do you not allocate for the buffer solution in the recipe as I had to use 1.8%, the fact you have not included this in your recipe confused me and I could not find additional information to satisfy my worry
Many thanks

“That is incorrect. There is a lot of information on the internet that can be very helpful and lots that is not.
Vitamin B and Vitamin C are a highly effective combination of vitamins, valued for their ability to brighten dull skin, improve the appearance of fine lines and wrinkles, improve firmness and improve skin tone as well as defend the skin against free radical damage.
Outdated and mis-interpreted research dating as far back as the 1960’s stated that these two vitamins do not combine well in skincare products. The variations of the vitamins tested were unstable and subjected to prolonged high temperatures, far outside of what would be considered normal ranges, which then showed the vitamin B to convert to nicotinic acid. The vitamin C that was used in these tests was the pure vitamin C not the type that is now safely used in skin care such as the stable sodium ascorbyl phosphate that we stock."

I’ve read elsewhere than Vitamin C and Vitamin B3 (Niacinamide) don’t combine well in one product – is this a problem with this recipe?

“Are you referring to the vitamin enriched lotion formulation or a water based serum that you have developed? When we developed the vitamin enriched lotion, we tested the pH and found it to be in the acceptable levels. Of course, different essential oils can change that, but I would not expect it to change to such a great extent. Please let us know which you are referring to, and we can look into it further.”
