GlossaryHuman Leukocyte Antigen (HLA)

group of proteins on cell surfaces aiding immune recognition

Human Leukocyte Antigen (HLA) refers to a group of proteins found on the surface of most cells in the body. These proteins play a crucial role in the immune system by helping it distinguish between the body's own cells and foreign invaders, such as viruses and bacteria. HLA typing is important in organ transplantation to ensure compatibility between donors and recipients, reducing the risk of rejection.

community Dermastamping — do you use hyaluronic acid as lubricant?

in Microneedling 3 upvotes 1 year ago

The conversation discusses using high molecular weight hyaluronic acid after microneedling to form a protective barrier, though it's considered expensive and offers marginal improvement. Users share experiences with different microneedling tools like derma rollers, dermastamps, and Dr. Pen, with some opting not to use any products on the scalp.
