Each skincare product consists of active substances and excipients. The active substances determine the effect of the product. Excipients are substances that support the product and determine the texture. Their function should not be underestimated because they control to what extent the active substances can do their work. Examples of excipients are anti-caking agents, binders, buffers, bulk agents, emulsifiers, dyes and preservatives.
A label does not differentiate between active ingredients and excipients, they are listed randomly. If you want to know what the product does, you should start by screening the active substances first.
It's good to know that the higher the ingredients are ranked in the list, the higher their concentration. So, you would like to see most active substances in the upper part of the list, with the exception of peptides, where a low concentration can be very effective. The preservatives and coloring agents are usually placed at the end of the list.
