Facial pigmentation is a common concern that often causes distress, particularly in individuals with skin types IV and above. Treatment varies based on the underlying cause. The most frequent causes include post-inflammatory hyperpigmentation (PIH) from acne or other inflammatory conditions, melasma, and lentigines.

Deeper pigmentation issues, such as pigmentary demarcation lines, lichen planus pigmentosus, pseudo-ochronosis, and certain birthmarks, may require advanced treatments like Q-switched Nd: YAG laser. Conditions like facial acanthosis nigricans and frictional dermatitis are more common in overweight individuals, making weight management and minimising friction essential alongside depigmenting treatments.

Effective management of facial pigmentation involves addressing the root cause and maintaining strict sun protection. Safe depigmenting agents, such as kojic acid, alpha-arbutin, glutathione, and azelaic acid, can help lighten pigmentation. Additionally, procedures such as chemical peels, microneedling, PRP, and laser therapy can enhance results. However, multiple treatment sessions are often necessary to achieve noticeable improvement.
