You may have heard the term PRP, perhaps in the context of the infamous “vampire facial” or in discussions about hair loss treatment. But regenerative skin medicine has expanded well beyond PRP alone. Today, platelet-derived growth factor (PDGF) therapy and advanced growth factor formulations are offering new possibilities for patients seeking deeper, more sustained skin and hair rejuvenation.
As a board-certified dermatologist certified in integrative dermatology, Dr. Obayan brings a nuanced, science-grounded perspective to these therapies. Here’s what you need to know.
PRP Explained: How Your Own Blood Becomes a Skin Treatment
Platelet-Rich Plasma (PRP) is derived from your own blood. During a PRP treatment, a small amount of blood is drawn, then spun in a centrifuge to concentrate the platelets, tiny cell fragments packed with growth factors and signaling proteins that play a central role in wound healing and tissue repair.
When this concentrated platelet-rich plasma is reintroduced to targeted areas of the skin or scalp, it delivers a burst of biological signals that stimulate collagen production, promote new cell growth, and encourage the body’s natural regenerative processes.
Because PRP is derived from your own blood, the risk of allergic reaction or rejection is extremely low, making it one of the safest regenerative options available in dermatology.
The Science of Growth Factors: Cellular Messengers That Decline With Age
Growth factors are naturally occurring proteins that act as cellular messengers. They bind to receptors on the surface of cells and trigger specific responses; stimulating cell division, collagen synthesis, new blood vessel formation, or tissue repair. In healthy young skin, growth factors are abundant. With age, their levels decline, contributing to slower healing and the visible signs of skin aging.
The major growth factors relevant to skin and hair rejuvenation include:
- Epidermal Growth Factor (EGF) — stimulates skin cell renewal and wound healing
- Platelet-Derived Growth Factor (PDGF) — drives collagen production and vascular repair
- Transforming Growth Factor Beta (TGF-β) — regulates skin remodeling and scarring
- Vascular Endothelial Growth Factor (VEGF) — promotes new blood vessel formation
- Fibroblast Growth Factor (FGF) — stimulates collagen and elastin production
PRP vs. PDGF: How These Two Regenerative Approaches Differ and When Each Makes Sense
PRP is a delivery vehicle: it concentrates many of the platelets and growth factors already present in your blood, then delivers them to a target tissue. Its composition varies from patient to patient and batch to batch, which means results can be somewhat variable.
PDGF-specific therapies represent a more targeted approach: rather than using a broad mixture of growth factors from a patient’s own blood, PDGF formulations (some derived from processed platelet concentrates, others from biotechnology) deliver a specific, concentrated dose of platelet-derived growth factor to the treatment area.
Both have their place in regenerative dermatology. The right choice depends on the patient’s specific concerns, treatment goals, and biology and this is exactly where a thorough consultation with a knowledgeable dermatologist makes a critical difference.
“The doctor and staff were very kind, personable, knowledgeable, and helpful! I appreciate that the doctor also has some knowledge about natural treatments along with her medical knowledge.”

How Nature of Skin Uses Regenerative Therapies: Facial, Scalp, and Beyond
PRP + Microneedling for Deeper Facial Rejuvenation
PRP and growth factor serums are frequently combined with microneedling to dramatically enhance results. Microneedling creates micro-channels in the skin that allow growth factors to penetrate deeply, where they can stimulate collagen remodeling and tissue repair at a level that topical products alone cannot reach.
Scalp PRP Injections for Hair Restoration
Injecting PRP or growth factor preparations into the scalp has become one of the most evidence-supported approaches to treating androgenetic alopecia (pattern hair loss) and other forms of hair thinning. The growth factors promote follicle survival, extend the active growth phase of the hair cycle, and improve scalp vascularity.
Improving Skin Texture and Tone With Biologically Based Treatments
Growth factor therapy is particularly valuable for patients seeking improvement in skin texture, tone, and overall vitality, especially those who prefer biologically based treatments over synthetic injectables.
What the Research Actually Shows About PRP in Dermatology
The evidence base for PRP in dermatology has grown substantially over the past decade. Multiple peer-reviewed studies have demonstrated significant improvement in hair density and follicle count following scalp PRP injections. Research on PRP combined with microneedling shows meaningful improvements in acne scars, skin laxity, and fine lines. The science behind growth factor formulations is also maturing, with encouraging data on their role in wound healing and anti-aging applications.
As with all emerging therapies, results vary and not every patient will be an ideal candidate. At Nature of Skin, we review the current evidence with every patient and set realistic expectations from the start.
Are You a Good Candidate for PRP or Growth Factor Therapy?
Ideal candidates for PRP and growth factor therapies tend to be patients with early-to-moderate hair thinning, those seeking facial rejuvenation with a preference for biologically derived treatments, and patients looking to enhance the results of microneedling and laser therapies with ongoing skin concerns like acne scarring, hyperpigmentation, or uneven texture who want a regenerative approach.
A comprehensive consultation including an evaluation of your skin and scalp health, medical history, and treatment goals is the essential first step.
Your skin is one of a kind. Schedule a consultation with Dr. Obayan and get a plan that treats it that way.
