Question from Claire

Ingestible skincare – is it legitimate? Some of the skincare products I use contain hyaluronic acid since using the products I have notices a considerable difference in the appearance of skin. I have since noticed that there are ingestible versions of hyaluronic acid available in the form of pills and liquid. Does ingesting certain skincare ingredients have the same effect as using them in topical creams?

Answer

Hi and thank you for an interesting question. The products and ingredients that are applied in cosmeceuticals to the skin are often digested and broken down when ingested unfortunately. Even oral collagen products have not scientifically proven any statistical absorption at low molecular weights. Hyaluronic acid is really a very fragile molecule and has a large molecular size, which means that the body will not easily absorb it through the intestinal lining either. If one makes the molecule smaller, it won’t work as well. In my experience it is best used as an injection or a topical application. I hope that this helps.
