I had a break out and tried a lot of products to lighten my acne scars but phytoniacin was the product i sticked to. It really lightened my dark spots and i've been constantly using it for 3 years!! I really really recommend it because i observed how fast it lightens my pimple marks. I also used the glow intensive essence although since i only had allowance then, i had to stop it. But since nacific has a promo of buy 1 get 1 im now able to use it again! Pls do check my skin care routine. https://youtu.be/NUUlM2GjLik i am so amazed by nacific!!! And i recommended it to my friends, they also loved it!!
