How to fade dark marks on the face caused by post-inflammatory hyperpigmentation after spot treatment

In general, dark marks appearing all over the face after spot treatment are usually due to post-inflammatory hyperpigmentation. This may be caused by factors such as thermal injury from laser treatment, chemical irritation, inflammatory reactions, improper postoperative care, or individual differences. Mild cases can often be improved with enhanced sun protection and skincare routines, or through medications prescribed by a doctor. More severe cases can be effectively treated with procedures such as chemical peels, photorejuvenation (IPL), or fractional laser therapy. It is recommended to consult a professional physician for advice.

Laser-induced thermal injury occurs when the skin sustains heat damage during treatment, stimulating melanin production and resulting in widespread dark marks. This can be managed under medical guidance with oral or topical medications such as vitamin E cream or hydroquinone cream. Chemical irritation refers to stimulation of the skin by certain chemicals during spot removal, which activates melanocytes. This condition can be treated with fractional laser therapy. Inflammatory reactions may arise when spots trigger skin inflammation, promoting melanin production and deposition. These can be managed with anti-inflammatory ointments as directed by a physician, such as erythromycin ointment or mupirocin ointment. Improper postoperative care—such as inadequate sun protection or moisturization—can lead to UV-induced pigmentation and dark facial marks. This can be addressed through enhanced sun protection and treatments like chemical peels. Individual variation refers to the tendency of individuals with darker skin tones to develop hyperpigmentation more easily. Treatments such as chemical peels, photorejuvenation, and fractional laser therapy are commonly used in these cases.
