It didn't do anything that it claims to do. Can be used for moisturizing the skin. That's it. Does no exfoliation or brightening. Now that I researched into this, you can't get AHAs and Vitamin C at such a low price as this serum. They don't even mention a concentration for the acids in it. Every real product with AHA/vitamin C in it mentions concentration as it's very important. Waste of 500 rupees. Save that money and buy a real AHA or Vitamin C serum from a good company.
