This is a great staple product to have, so soothing when you need to go back to basics. Little goes a long way, you really don't need much. I have acne prone, combination, fussy skin and this has never broke me out. I love anything with niacinamide in it and this is a natural form of B3, so even better! This product by Cosrx is always out of stock so that says it all really! Make sure you sign up for alerts when this is back in stock and snap it up! You won't regret it.
