What to do about post-inflammatory hyperpigmentation after laser spot removal

Lasers are commonly used to remove pigmented spots by targeting the skin and breaking down the pigment particles, thereby lightening or eliminating the spots. However, post-treatment hyperpigmentation may occur. This is caused by the stimulation of the skin during laser treatment, which makes the local melanocytes overactive and leads to excessive production and deposition of melanin. This condition is somewhat normal, but appropriate measures should be taken to alleviate and prevent it.

1. Avoid sun exposure: Ultraviolet radiation is one of the main factors that promote melanin secretion. Therefore, patients should avoid direct sunlight after laser treatment. Use high SPF sunscreen when going outdoors and reapply it as needed.

2. Use skin-lightening products: Choose products containing ingredients such as vitamin C, arbutin, and hydroquinone. These ingredients can inhibit melanin synthesis, promote its metabolic breakdown, and thus reduce pigmentation.

3. Maintain even hydration: Regularly use moisturizing products to keep the skin hydrated, which helps promote epidermal cell renewal and evens out skin tone.

4. Gentle exfoliation: Moderate exfoliation can promote metabolism, but care should be taken not to over-stimulate the skin, as this may worsen pigmentation.

5. Regular follow-ups: If the hyperpigmentation is severe or persists for a long time, patients should return for follow-up visits. Doctors can assess whether further treatments, such as additional laser therapy or other medical aesthetic procedures, are needed.

Hyperpigmentation following laser pigmented spot removal is not a cause for excessive concern. With proper treatment and care, most patients can see improvement in their pigmentation issues.
