Can scabs form or pigmentation become darker after pigmentation laser treatment?

If a pigmentation laser is attempted to be removed with strong energy all at once, it can stimulate the melanocyte, causing the pigment to temporarily darken (post-inflammatory hyperpigmentation, PIH) or scabs to form. Therefore, it is a principle to proceed with lower energy over multiple sessions. Thorough post-treatment hydration and UV protection are also important in reducing these reactions.
