dark patches on side of face

Dark patches on the side of your face can indeed be concerning, but understanding the underlying causes might help clarify things for you. The dermatologist’s mention of post-inflammatory hyperpigmentation (PIH) and melasma are common conditions behind such patches. PIH occurs when your skin darkens following an inflammation or injury, like acne or minor trauma, due to increased melanin production in response to the inflammation. Melasma, on the other hand, is often triggered by hormonal changes, like during pregnancy, or from sun exposure, leading to more widespread pigmentation. Both conditions result in hyperpigmentation but involve slightly different mechanisms. Since you’ve explored changes in skin care and avoided irritants like makeup, focusing on targeted treatments could be beneficial. Broad-spectrum sunscreen with high SPF is essential, as it protects against UV rays that can intensify pigmentation. Additionally, topical treatments such as hydroquinone, azelaic acid, or retinoids, either over-the-counter or prescribed by a dermatologist, can gradually lighten these patches. Sometimes, chemical peels or laser therapy may also be recommended, particularly if topical treatments aren’t enough. Lifestyle modifications, like avoiding direct sunlight or wearing protective clothing can also be part of the management strategy. However, it’s crucial to follow a dermatologist’s advice since they can tailor the treatment to your specific situation. Keep in mind that these treatments can take time to show noticeable results, and consistency is key. If you notice any irritation or no improvement, revisiting the dermatologist for further evaluation and treatment adjustment would be a prudent step.
