PRP (platelet-rich plasma) and PRF (platelet-rich fibrin) therapy in Los Angeles by Dr. K. Charles Kim uses the patient's own concentrated growth factors to stimulate hair restoration, skin rejuvenation, and tissue healing. Because the active ingredient is the patient's own biology, PRP and PRF carry minimal risk of allergic reaction or rejection. Dr. Kim offers these treatments as standalone therapy and in combination with microneedling, facial fat transfer, and hair restoration protocols.

A small blood sample is drawn from the patient, then centrifuged to isolate concentrated platelets and growth factors. The resulting plasma is either injected directly into target tissue (scalp for hair, dermis for rejuvenation) or applied topically with microneedling for transdermal delivery. PRF differs by forming a fibrin matrix that releases growth factors over a longer period. The full process — draw to treatment — takes approximately one hour and is performed entirely in-office.

Day 1: Mild soreness or pink discoloration at injection sites; immediate return to normal activity.

Weeks 2–6: Initial improvements in skin quality or hair density become visible.

Months 3–6: Full result emerges; a series of 3–4 sessions spaced 4–6 weeks apart is typical, with annual maintenance recommended.

Frequently Asked Questions

Most patients see the best results from a series of about 3 PRP treatments spaced several weeks apart, with improvement building gradually as the growth factors stimulate renewal. Maintenance sessions can sustain results. Dr. Kim's practice designs a personalized plan for your goals.

PRP treatment is generally well tolerated; a topical numbing cream minimizes discomfort, and most patients feel only mild sensations during the procedure. Any tenderness afterward is brief. Dr. Kim's practice prioritizes your comfort throughout each session.

PRP is obtained by drawing a small sample of your blood and spinning it in a centrifuge to separate and concentrate the platelets and growth factors, which are then applied or injected into the treatment area. The process is quick and done in-office. Dr. Kim's practice prepares each PRP sample with care.

Platelet-Rich Plasma (PRP) is a concentration of healing growth factors derived from your own blood, used to rejuvenate skin, improve texture, and stimulate hair growth. Because it comes from your body, it is a natural, regenerative treatment. Dr. Kim's practice offers PRP for skin and hair restoration in Los Angeles.
