L-Ascorbic Acid is a fancy word for Vitamin C.
What’s Vitamin C?
For those of you who don’t know, it’s an antioxidant that’s essential to collagen biosynthesis.
Of course there are other types of Vitamin C out there. Namely, there’s MAP (Magnesium Ascorbyl Phosphate), SAP (Sodium Ascorbyl Phosphate), AP (Ascorbyl Palmitate), and ATIP (Tetrahexyldecyl Ascorbate). But those are known as Vitamin C derivatives.
L-Ascorbic Acid, on the other hand, is the real deal. It’s Vitamin C in its purest form. You know, the naturally occurring kind.
But, does that make it better than the rest?
Well, in some regards it does.
It’s undoubtedly the most powerful and effective form of Vitamin C.
In fact, it has the greatest antioxidant potential in the bunch (1). As an antioxidant, it can defend your skin against things like free radicals (particularly from Reactive Oxygen Species) and UV damage.
But beware, if you have sensitive skin, you might want to take a hard pass on this stuff and opt for a derivative. The thing is that L-Ascorbic Acid is notoriously unstable. It has an extremely low pH of 3.5 which can irritate the heck out of sensitive (and not-so-sensitive) skin.
