Data Availability: Successful treatment of laser-induced hypopigmentation with platelet-rich plasma

Introduction: Platelet-rich plasma (PRP) treatment, obtained from a patient’s own blood and enriched with a high concentration of platelets and growth factors, has become increasingly popular and is now commonly used for conditions such as hair growth, psoriasis, skin rejuvenation, hyperpigmentation, and vitiligo. PRP is a versatile treatment that can help patients cosmetically and functionally. By processing a patient's blood, PRP allows for platelets and growth factors to be reintroduced into the skin, which can promote healing, tissue regeneration, and in this case, a restoration of skin pigmentation. 

Case presentation: This case report demonstrates the use of PRP therapy on a 28-year-old Caucasian female with no significant past medical history suffering from hypopigmentation following laser hair removal. After topical corticosteroid treatment was tried and failed, three sessions of PRP were performed, spaced 6 weeks apart, resulting in almost complete clearance of hypopigmentation. 

Conclusion: The positive outcome observed in this patient suggests that PRP may be a promising treatment option for various types of hypopigmentation, potentially offering a non-invasive and effective approach for patients suffering from this condition.
