Objectives: Microneedling Radiofrequency with Platelet-Rich Plasma (PRP) The micro needles in MNRF creates micro injuries to the dermis to initiate a healing process,Injured cells release growth and wound healing signals to undifferentiated cells which cause production of new collagen for rejuvenation. This new collagen fills in the wounded areas, acne scars, and thickens the overall skin. This process of new collagen can last from weeks, to up to 6-8 months after the last session. The heat generated by RF (Radio Frequency) produces a healing response that allows the skin to tighten & thicken naturally Introduction: Microneedling RF for acne scars is a FDA approved minimally invasive, minimal downtime treatment that helps to build collagen, tone and tighten the skin and minimize signs of ageing. Microneedling with RF combines different modalities proven to help the appearance of the skin by stimulating collagen and elastin. Microneedling also known as collagen induction therapy uses very small needles to penetrate the skin layers. The RF stands for radio frequency, which automatically delivers heat to the deeper skin layer through the microscopic needles stimulating collagen and elastin for tighter skin. Materials / method: After cleansing your skin, your doctor will apply a topical anesthetic. This will need to set for at least 30 minutes before microneedling begins. During this time your doctor will apply a numbing cream for 30mins and a FDA-approved MNRF device will be used for your face and move it across the face in stamping motions.. A syringe of blood will be drawn, usually from your arm, while your face is numbing. The blood is then put into a centrifuge, which separates the PRP from the blood. The PRP solution is then injected into the treatment area, either during or after microneedling. Results: The microneedling treatment opens channels into your skin, allowing for good penetration of the PRP.Microneedling RF with Platelet Rich Plasma (PRP) will help you to improve your skin’s overall appearance, tone, laxity, fine lines, acne scars and stretch marks. micro needles and radiofrequency energy, induce new collagen formation creating tighter, firmer and brighter skin. Platelet Rich Plasma or PRP which contain nutrients from stem cells is applied to the skin after immediately after the microneedling.It takes some time for your body to produce collagen about 1 – 4 weeks for full result. Conclusion: The microneedling treatment opens channels into your skin, allowing for good penetration of the PRP.Microneedling RF with Platelet Rich Plasma (PRP) will help you to improve your skin’s overall appearance, tone, laxity, fine lines, acne scars and stretch marks. Patients are require to complete a minimum series of 6treatments spaced 4 weeks apart. Some issues will require more treatments,depending on your skin type & issue.it can be combined with other treatments likr laser,peels etc for even better results.
