Uh no... Only that collagen that is specifically identified as "animal collagen" or "animal keratin" comes from cows and other "animal" remains that come from slaughterhouses. If it says bio-collagen or bio-keratin or if it only says, collagen and keratin enriched for example, that collagen and keratin is from human sources and usually murdered babies.
Sorry. If you don't like hearing the truth I don't know what to tell you. It took me several years to sift through Planned Parenthood and the pro-deather's propaganda to learn the truth and then to find products that do not use aborted babies.
