If the word ‘bioavailability’ doesn’t top your list of skincare concerns when purchasing a new vitamin C serum or moisturizer, we’d advise you to investigate the concept a bit more. According to PhaFix.com, “bioavailability is the degree to which a drug or other substance becomes available to the target tissue after administration”. What encompasses bioavailability may just also extend into the world of skincare.
Why would this matter when it comes to what you’re putting on your own dermis? Because bioavailability determines how much of an ingredient is actually being absorbed by your body, i.e. what’s just sitting on your skin versus actually going into it.
PhaFix.com says there are three factors are the sole gatekeepers between you and getting the most out of your skincare purchases. What is first determined is how much of an active ingredient is present. Second, what base carrier (water, oil, emulsifiers, etc.) is in the product and how it will help penetrate the skin. Third, we have to see if the active ingredients are small enough to effectively reach the epidermal layer. If the ingredients are too large, then the product will not absorb into the skin. According to Raconteur, nanotechnology is currently being developed where physicians are transforming active ingredients into nano-sized particles. These will then be put into skincare products, making them more easily absorbed because of their small size.
Because nanotechnology isn’t available quite yet, we put our hope in our favorite brands, They Call Her Alfie. Brainchild of Sporteluxe founder Bianca Cheah-Chalmers and her need for immediate, visible results from non-toxic ingredients. The best part: the BSX technology. The BSX is a new transdermal delivery technology that allows the skin to absorb and retain key ingredients faster and longer. This makes visible effects quicker and lasting.
