These are acids which exist in vegetable organisms (citric, tartric, malic, oxalic and many others), in stomach of animals (hydrochloric acid), in volcanic emissions (also HCl, hydrogen sulfide), etc.
Citric or malic acids are natural products.

Because it has acids in it. Natural acids, but acids all the same.
Natural acids and oxygen
Natural acids can be obtained from the nature, either directly or from a simple industrial process, and they are also called as mineral acids. Artificial acids should be synthesized using simpler compounds. Among the common examples are complex organic acids which cannot be derived naturally.

Acids can be classified into natural and synthetic acids based on their source of origin. Natural acids are derived from natural sources like fruits (citric acid in lemons), plants (tannic acid in oak bark), and animals (uric acid in urine). Synthetic acids, on the other hand, are produced through chemical processes in laboratories or industries (sulfuric acid, hydrochloric acid).
I assume they're referring to the natural oils on our skins. That would lead me to say "fatty acids."
Natural acids are organic compounds that have acidic properties, mostly derived from plants or animals. Examples include citric acid from citrus fruits, acetic acid from vinegar, and lactic acid from dairy products. They play a role in food preservation, flavor enhancement, and in skincare products.
