Detailed answer

Spot treatments can be effective in reducing post-inflammatory hyperpigmentation. Ingredients such as hydroquinone, kojic acid, retinoids, and vitamin C can help fade hyperpigmentation by inhibiting melanin production and promoting cell turnover. It's important to apply the spot treatment only on the affected areas to avoid irritation or drying out the surrounding skin. Additionally, it's crucial to use sunscreen during the day to protect the skin from further damage and prevent the dark spots from worsening. Consistent and prolonged use of spot treatments along with a comprehensive skincare routine can yield visible improvements in the appearance of post-inflammatory hyperpigmentation.
