Is this a chemical burn? How to treat hyperpigmentation? (Photo)

It's important to approach this situation with care and seek professional guidance. Based on your description, here are some insights and recommendations:

Chemical Burn Possibility: The use of potent acidic skin lightening products, especially those containing hydroquinone, can sometimes lead to irritation or chemical burns, particularly if used improperly or if the concentration is too high. A dark line over the bridge of your nose could be a result of irritation or post-inflammatory hyperpigmentation from such products.

Hyperpigmentation Treatment: To address hyperpigmentation safely, consider the following steps:

Discontinue Use: Stop using any current products that are causing irritation or have not been prescribed by a dermatologist.

Gentle Skincare: Switch to a gentle skincare routine that focuses on soothing and hydrating the skin. Look for products with ingredients like niacinamide or ceramides.

Sun Protection: Use a broad-spectrum sunscreen daily, as UV exposure can worsen hyperpigmentation.

Consult a Dermatologist: It's crucial to have a professional assessment to determine the exact cause of the discoloration and receive a personalized treatment plan. They might suggest treatments such as topical retinoids, azelaic acid, or professional procedures like chemical peels, laser therapy, or microneedling.

Restoring Skin Health: Focus on restoring your skin barrier by using products that promote healing and avoid any harsh or abrasive treatments until your skin has recovered.

Consulting with a dermatologist will provide you with the best course of action to safely and effectively treat your skin concerns.
