Kajal has always been the essential makeup product in my beauty kit, whether I create a bold, dramatic eye makeup look or keep it subtle and simple! I tried out this Mamaearth Charcoal Black Long Stay Kajal Black and I’m highly impressed with it. Waterproof and smudge-free, the kajal glides on effortlessly, adding a glossy sheen and a rich colour that stays for 11 hours.I think my eyes love it too. Do you? Just like a primer, you can use a foundation on your eyes before applying kajal for a long-lasting effect.
