Reviews Summary
Customers say this serum has a light, silky texture that absorbs well into the skin. Many users report reduced oiliness, especially in the T-zone area. The product receives praise for minimizing the appearance of pores and evening out skin texture. Long-term users mention consistent results with regular use, with many on their third or fourth bottle. While most find it gentle, a few note it didn't suit their skin type. Common feedback includes its effectiveness for combination skin types and its non-sticky formula. Reviews highlight its compatibility with other skincare products.

    Like it

    To be honest, I'm not really sure what it does for my skin. I occasionally incorporate it into my routine because it's probably doing something? I like that it doesn't give me as many closed comedones like some other ones I've tried.

    A Skaincare Staple

    I throughly enjoy this niacinamide serum. It packs a punch. I use this serum everyday after double cleansing and a hydrating serum. Helping to reduce oil and redness, the appearance of pores, and including 1% hydrating hyaluronic acid; this effective and gentle multitasker is not to be overlooked.
