What should you know about plasma pen for pigmentation?

A plasma device delivers energy near the skin surface and can leave small crusted points while the area heals. Pigmentation is not one diagnosis: it may follow acne or irritation, relate to sun exposure, or reflect a condition that needs a different treatment. Treating an unexplained dark patch can obscure its appearance or trigger post-inflammatory darkening, especially in deeper skin tones. A clinician should assess the area, its pattern, and any recent change before choosing a device.

Have the treatment area examined and disclose recent tanning, active eczema, cold sores, medicines, and a tendency to form raised scars. Follow the clinic’s instructions about cleansing and products. During healing, do not pick crusts, scrub the skin, or apply unapproved acids or retinoids. Protect the area from sunlight with clothing and the recommended broad-spectrum sunscreen, because ultraviolet exposure can deepen uneven colour. Arrange review if the pigment does not settle as expected.

Contact the treating clinician promptly for spreading redness, increasing warmth, pus, worsening pain, fever, blistering, or swelling near the eyes. Seek assessment for a pigmented spot that changes quickly, bleeds, develops an irregular edge, or looks unlike your other marks; cosmetic treatment should not delay evaluation of a potentially concerning lesion.

What is the likely cause of this pigmentation, and is a plasma pen suitable for my skin tone? What alternatives could reduce colour without surface injury? Which products should I stop, and what will you use for wound care and sun protection?
