Laser treatment of acne scarring in skin of colour

Acne vulgaris is a chronic inflammatory skin disorder that affects patients of all skin types. Acne scarring affects up to 95% of patients. Laser treatment is the most effective treatment for acne scarring. Adverse effects (AEs) include pain, infection, erythema, postinflammatory hyperpigmentation (PIH), hypopigmentation and scarring. Patients with darker skin types are more prone to developing PIH, arising as a result of inflammation, which can be intrinsic or extrinsic. There is concern that laser treatment may not be suitable for patients with skin of colour (SOC) due to the risks of AEs. However, the use of appropriate treatment protocols can help to mitigate these risks. Clinicians should consider the type of acne scarring and skin type of the patient when choosing the most appropriate laser. Laser treatments should be offered to patients with SOC, who should be fully informed of the risks before embarking on treatment. It is important to note that no treatment will eliminate scarring completely, but lasers can significantly improve the appearance of acne scars. Laser treatment for acne scarring can be performed safely and effectively when tailored to the patient's needs and skin type. Further studies are needed to evaluate the use of lasers for patients with SOC.
