WHAT YOU BUY MAY NOT HAVE THE FUNCTION YOU WANT
Here is an example of algae extract in inducing heme oxygenase-1 (HO-1) in primary human dermal fibroblasts (HDF). HO-1 regulates heme metabolisms from leaky blood vessels of the suborbital dermis. Accumulated heme generates the appearance of violet pigment in this area, producing dark coloration through the skin and the production of free radicals and inflammation. Below Fig. shows algae extract #1 is not active in inducing HO-1 and algae extracts #2 and #3 can stimulate HO-1. If you are a manufacturer of the raw material, we can tell you whether your algae extract is active in inducing HO-1. If you are skincare brand or OEM, we can tell you whether the algae extract is functional as needed.
WHAT YOU BUY MAY NOT BE TRULY WHAT YOU WANT
Here is an example of high performance liquid chromatography (HPLC) analyses of two Camu camu extracts. The Fig. below shows one that is the real Camu camu extract (green) with other compounds eluted at earlier time and the other that is adulterated (red) with a single peak. Camu camu is known to contain high levels of ascorbate (vitamin C). To confirm which peak is vitamin C, a standard vitamin C is injected (pink). There is an overlap of vitamin C peak with the true Camu camu extract but no overlap with the adulterated Camu camu extract.
IS YOUR FORMULATION STABLE?
Below is an example of the measurements of total antioxidant capacity (TAC) of finished products as a function of time. The Fig. below shows that the formulation one year after manufacturing lost about 33% of its TAC when sealed in a plastic bag and 78% when left open.
