Both products have their own advantages, so it's best to experiment with both to see which one works best for your individual needs. **

Serum is produced by collecting blood from a donor and allowing it to clot. The clot is then removed by centrifugation, leaving behind the liquid portion of the blood, which is the serum.

Serum can be stored at low temperatures to preserve its stability and integrity for future use. **

Using serum instead of primer can be a great alternative for those looking for a more lightweight and hydrating option. Serums are packed with active ingredients that can help improve the overall health and appearance of the skin, while also providing a smooth base for makeup application.

It is important for individuals to carefully check the ingredients of the eyelash serum and consult with a knowledgeable religious authority if they have any doubts about its permissibility. **
