Question 1

What PERCENTAGE of Vit C strength is the serum?

Accepted Answer

I'm late seeing this, but I emailed the company in June asking this question and this is the reply they sent:"Thank you for your interest in Mad Hippie!  The percentage of Vitamin C needed in skin care products varies depending on the form of Vitamin C used.  We use a very stable and bioavailable form of vitamin C called sodium ascorbyl phosphate.  Sodium ascorbyl phosphate is approximately twice as effective as L-ascorbic acid, the most commonly used form if Vitamin C used in skin care, which is not utilized as well by the skin.  We use approximately a 10% concentration of sodium ascorbyl phosphate, which is equivalent to about a 20% concentration of L-ascorbic acid in its effectiveness.  Most of the L-ascorbic acid, when applied, sits on the skin's surface without being absorbed and utilized and often causes irritation as a result. The primary difference is that sodium ascorbyl phosphate, the form of vitamin C that we use, has a salt attached to it, allowing it to penetrate the skin's lipid barrier and making it more bioavailable.  This also makes it much more stable and less prone to oxidation, which is a huge problem with L-AA."It's a great serum and company!

Question 2

how fresh is this product?

Accepted Answer

I've had the opposite experience - when I ordered directly from Mad Hippie's website, the serum was thicker and colorless. I thought I would try to save a few bucks and order from the Amazon seller CB Select (I actually couldn't find the name of the seller from the product page, so assumed that I was buying from Mad Hippie via Amazon - maybe I just have no common sense, but the website layout could also be purposefully misleading), and when I got the bottle, the serum was runny and yellow. To be fair, this may be due to the packaging/shipping conditions, since I ordered this in the summer when it's very hot outside. However, I expected the product to be in better shape, especially because I'm going to be putting it on my face...

Question 3

What is the PH?

Accepted Answer

Sodium ascorbyl phosphate is a vitamin C derivative synthesized to deliver the same benefit as Ascorbic acid which naturally occurs at a pH of around 3.5 which is fairly acidic. Its acidity creates problems in emulsions. Emulsions are carriers like lotions and creams formulated to make products look and feel nice.  The addition of a phosphate group to ascorbic acid, whether magnesium or sodium, raises the pH level it can survive in to greater than 7.

Question 4

Can this be used in the undereye area?

Accepted Answer

Yes...I use it around the whole eye except eyelid.  Great product!!
