A history of keloid or unusually raised scars should be discussed before elective PRP or microneedling. Using your own blood does not remove the effect of skin injury, and evidence about treating scars is different from evidence that a procedure cannot cause a new scar.

Is a keloid the same as any raised scar?
No. DermNet describes keloids as excessive scars that can extend beyond the original wound. Hypertrophic scars remain within the area of the original injury and are more likely to regress. The distinction matters when planning another procedure.
Do not diagnose the scar from an online image alone. Bring photographs, the history of the original injury and any treatment you received. A clinician may need to examine the area or obtain specialist advice before deciding what the history means.
Can a small injury matter?
Keloids can follow relatively minor skin injury as well as surgery, burns, acne or other inflammation. The affected site and personal history help shape risk. A small needle is still a skin intervention, even though it differs from a surgical incision.
DermNet advises avoiding unnecessary cosmetic procedures in keloid-prone people and areas. That does not create a universal ban on every medically indicated procedure. It supports an individual risk-benefit discussion before an elective treatment is chosen.
Does PRP being natural remove scarring risk?
No. PRP is prepared from your blood, but collection, preparation and administration still involve a procedure. Needling, inflammation, infection and individual healing responses remain relevant. Natural is not a clinical safety category.
A clinic should explain the proposed method and its evidence rather than promise that your own blood prevents complications. An uncomplicated previous injection is useful history, but it cannot guarantee that another site or a more intensive combination will behave identically.
Ask our concierge what assessment is appropriate. Share the question you want answered and ask which records would help.
What if PRP is advertised as a scar treatment?
Research into treating a scar asks a different question from whether PRP can be used without causing a scar in someone prone to keloids. Acne scars, hypertrophic scars and keloids are also different conditions.
Do not treat a claim about improved skin texture as evidence of keloid prevention. If your main concern is an existing raised scar, establish its diagnosis and compare recognised treatment options with a clinician experienced in scar management. A standard facial package may not address the problem.
What should I tell the clinic before booking?
Describe scars after piercings, vaccinations, surgery, acne or previous aesthetic treatment, especially if they spread beyond the original injury or continued growing. Include family history, symptoms and what treatment helped or worsened them.
Also disclose medicines, active skin disease and previous infection or pigmentation changes. A consultation should explain whether the proposed site and technique are appropriate, what remains uncertain and whether a specialist opinion or non-procedural alternative is preferable.
What should an honest treatment plan include?
It should record the decision, the specific risks discussed, realistic benefit and what aftercare or review would be available. A patch or small test area, if proposed, cannot promise that all later treatment will be free from scarring.
Take time to decide. If the expected cosmetic benefit is modest and the personal risk is meaningful, deferring treatment can be the better outcome. Do not accept a guarantee of scar-free healing or a claim that a premium device eliminates your individual history.
What does premium care mean in practice?
At the premium end of published London hair-PRP menus, Harley Street Skin Clinic lists £600 with a doctor, £750 with a senior doctor and £900 with a lead doctor per session. Those are that clinic's hair-treatment prices, not a quote for a facial, a guarantee of superior results or The London PRP Clinic's fees.
Ask for an individual written quote after the diagnosis and suitability discussion. It should explain the proposed procedure, who performs it, review arrangements, alternatives and what happens if treatment is deferred. A premium decision can be a reason not to proceed; a high price cannot make an unsuitable procedure appropriate.
Discuss your goals, suitability and a complete quote on WhatsApp. An enquiry starts a discussion; it does not confirm availability or commit you to treatment.
