It sounds like you may be experiencing skin discoloration and hyperpigmentation as a side effect of using the skin lite cream. To help improve the darkening of your face, you can try using a skin lightening cream containing hydroquinone, kojic acid, and glycolic acid. One option is "Melalite XL cream" which can be applied once at night for a few weeks. Additionally, using a broad-spectrum sunscreen during the day with at least SPF 30 is essential to prevent further darkening of the skin. Make sure to consult a dermatologist for a proper evaluation and personalized treatment plan.
