Formation of the Platelet Plug

10.4K
The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

Structure and Function of Platelets

4.5K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Summary

Platelet-rich plasma (PRP) treatments may unexpectedly increase skin pigmentation, particularly on the face. Researchers advise caution and suggest avoiding PRP for treating post-inflammatory hyperpigmentation.

Area of Science:

  • Dermatology
  • Regenerative Medicine

Background:

  • Platelet-rich plasma (PRP) is an autologous blood product concentrated with platelets, widely used for facial rejuvenation.
  • Its application aims to stimulate collagen production and improve skin texture, often for wrinkle reduction.

Purpose of the Study:

  • To investigate the occurrence of increased hyperpigmentation following Platelet-rich plasma (PRP) applications.
  • To evaluate the efficacy and safety of PRP in treating post-inflammatory hyperpigmentation, especially after laser therapy.

Main Methods:

  • Observational analysis of patients undergoing Platelet-rich plasma (PRP) therapy for facial rejuvenation.
  • Clinical assessment of skin pigmentation changes, including pre-existing pigmented lesions, post-PRP treatment.

Main Results:

  • Multiple patients experienced increased hyperpigmentation after Platelet-rich plasma (PRP) treatments intended for rejuvenation.
  • One case showed increased pigmentation over pre-existing pigmented lesions post-PRP application.
  • The study observed a potential for PRP to exacerbate pigmentation in the facial region.

Conclusions:

  • Platelet-rich plasma (PRP) may lead to increased skin pigmentation, particularly in facial areas.
  • Caution is recommended before and after Platelet-rich plasma (PRP) application due to potential pigmentation side effects.
  • Platelet-rich plasma (PRP) is not recommended for treating post-inflammatory hyperpigmentation.
