As Dr Ritu rightly suggested, I am of the same opinion. You can also take Berberis Aquifolium tincture 10 drops in 1/4 cup water twice a day for 2 months to purify your skin internally. The external application can be used in the form of Berberis Aquifolium cream to lighten the dark skin.
Do not resort to scraping and puncturing the pimples
as it will only result in deeper infection and worsening of the condition.
