Most of these are used for elemental analysis which depicts the threshold value
of heavy metals present in it except FTIR and Raman spectroscopy.

The majority of these techniques have limitations like TLC, GC-MS, and NAA

are destructive in nature. Lip prints can have saliva DNA in the print. Lip
cosmetics are an excellent source of salivary DNA analysis which shows the

biochemical and proteins found in blood. It can also provide information on
the diseases present in the body and the mouth of the host including diabetes

and heart diseases.

LIMITATIONS

Previous research works on this topic contain insufficient data and require a
detailed study of lipsticks to effectively characterize them. And to link an

unknown sample there is a need for databases of lipstick samples or a statistical

model. However, no studies have been done on the lipstick samples from the
Indian market for the local brands available.

CONCLUSION

Exposing yourself to a small amount of lipstick is not harmful, but if you are

someone who uses it regularly and frequently reapplies, it can cause harm.
When lipstick samples were analyzed using ATR-FTIR spectroscopy, which is

a non-destructive process, results were obtained and were able to predict their
respective brands, proving discrimination of lipstick samples is possible.

In the future, there are chances of creating a database of lipstick samples, which

will help in identifying lipstick samples and establish connections between the
culprit and victim to solve a crime.
