Letters | End cruelty to animals in the name of beauty or health: stop buying

From cosmetics to medicines, many companies use animals to test their products, but we as consumers might not be aware of this. Famous multinational beauty brands test on animals while creating their cosmetic products. I am saddened to learn that tens of millions of animals are subjected to such testing worldwide every year.
Companies could replace animal testing by constructing human tissues. Reconstructed human tissue like EpiDerm can be used to predict the skin irritation potential of chemicals, and fully replace testing done on rabbits.
Another new technique, known as “human on a chip” systems, allow researchers to replicate human cell membranes to investigate how a chemical or drug affects cells. This model could be used for testing potential drug candidates for Covid-19, instead of carrying out experiments on animals.
