Suitable for all skin types, recommended for oily and acne skin.

Best niacinamide serum thus far
I love how velvety and light weight this serum is. Been using for a week or so and can see some changes in my blemishes. Thinking of buying another for my layover skin care bag now. I can’t get enough.
