If you;ve been using Melaglow and Aha glow, it's time to go back to basics:
These products damage the pigmentation of your skin, so it's no wonder after using them for a month or so you start finding your skin getting darker than before.
The remedy would be a simple one: Exfoliate to remove all the skin cells,
Use a mixture of lemon juice and egg white to treat the skin 2 times a day.
Stay out of the sun as much as possible.
Keep doing this routine for a few months, and your blemishes will go and your skin will look very clear.
