What Are Serum Tears
Definition Autologous vs. Allogenic
Serum tears is the umbrella term for eye drops made from human serum. When the serum comes from your own blood, we call it autologous serum tears. If its sourced from a screened donor, its allogenic. Both contain natural growth factors, vitamins, and proteins that help keep the ocular surface healthythings you wont find in standard lubricating drops.
How They Differ From Conventional Drops
Artificial tears mainly add moisture, but they lack the bioactive ingredients that actually support cell repair. Serum tears, on the other hand, deliver those healing molecules straight to the eye, which can be a gamechanger for people with severe or chronic dryeye disease.

If youre a pet parent, ask your vet whether serum drops are an option for your furry friend.
Allogenic (Donor) Serum Tears
