According to Merriam-Webster, bioavailability is the degree and rate at which a substance is absorbed into a living system or is made available at the site of physiological activity. What does that have to do with the price of tea in China you might ask? In regards to your skin care products, everything!
One big factor in whether a product will work for you is whether enough of it can actually get to where it needs to go in your skin. First off, does the product you are using have the right amount of active ingredient? If the dosage is too small, it cannot work properly. Conversely, if the dosage is too high, it you are more likely to see the results of side effects. Ask your qualified esthetician if the product you are using has the correct concentration of active ingredient to meet your needs.
Another problem can be interference that prevents the product from absorbing properly. Residue from cleansers, makeup and sunscreen can all form a barrier on your skin’s surface, affecting the absorption of subsequent products. The biggest culprits are cleansing creams and scrubs, which generally leave some type of occlusive residue, such as cetyl alcohol or cetearyl alcohol. Clear foaming cleansers tend to be the “cleanest”. Makeup and sunscreen can settle into pores and skin imperfectons, but will usually come off with a good cleansing regimen. Regular facials can also help ensure that your skin is free and clear of residue and blockages.
