10% Niacinimide + Zinc Treatment Serum

This helps my skin so much to control oil and shrink pores. I use this with hyaluronic acid so my skin does not dry out. I love this product because it is light and non-greasy. It only takes two or three drops and I use it twice a day.

This Cosmedica Niacinamide and Zinc Treatment is a medium weight serum that goes on easily and can be applied under other glycerin-based serums and moisturizers without pilling. Having used niacinamide with zinc for some time, I am aware that these ingredients actually do address skin inflammation and other common issues. Zinc PCA, the form of zinc in this product, is commonly used to help with acne. Niacinamide helps improve skin texture and can also improve a dry skin condition. I have used it to minimize dark spots. There is an ounce of serum in the Cosmedica brown bottle with its glass dropper. Because so little is used in the two treatments, morning and night, I will probably go through this bottle in about a month and a half. It appears to be a good product that does not remain sticky once applied, as some do.If you are just beginning to use niacinamide and you purchase this product, consider mixing this with another glycerin-based product to begin with in order to sensitize your skin. Some products contain half of the niacinamide that this product contains; beginning with a full 10% might cause initial irritation. But, halving the serum for a while will make it last longer!This product container says that the product is cruelty free, something that I think is important when purchasing cosmetics. However, the leaping rabbit logo is not evident on the box.

I normally use 3 different products to get all of these ingredients so I was excited to be able to use just one product & still get the same results. There is a slight scent to this,nothing major. It went on easily and wasn't sticky after it dried in about a minute & was able to put my moisturizer on. My skin feels soft & smooth the next day,I can't wait to see the future results.

Do not buy this product. Did absolutely nothing for my face. Wasn’t comfortable. Had to layer my normal products with it. Don’t waste your money.

Serum is thick, so it will last long, even if u use it every day, I use it with other serums. I have only been using about 2 weeks, I don't notice a difference yet, but I'm not giving up. I like a lot of their other products. I don't smell any scent from it. I consider myself to be sensitive skinned and I haven't had any issues.

I've added this niacinamide & zinc serum to my facial skincare routine, using it in the morning only (because I use Tretinoin at night), and while I can't know for sure exactly what impact it's having on my skin in the longer-term, it's definitely making my skin feel soft, smooth, and 'plumped'. I use it on cleansed skin, before applying moisturizer and sunscreen. It has a very faint, pleasant fragrance, applies evenly and absorbs well, without any greasiness or residue. It feels quite soothing, in fact, and my moisturizer applies nicely on top once the serum has absorbed (which happens instantly, basically).A couple of drops goes a long way, and because I'm only using it once per day, this bottle should last me a good while.

I find most of these things help as long as you continue to use them. Not sure if it is just a temporary fix or that it is actually improving the skin, but it is hard to tell as I am aging and my wrinkles do seem to get worse every year. So it could just be the normal curse of gravity. And I find it doesn't hurt to use this type of product.

I've actually used a very similar product 2x/day for years. It's 10% niacinamide + 1% zinc & sells for around $10.80 for a 60 ml bottle. I've had good results with it & it's become a staple in my routine but I'm always willing to try something else.I have this serum pictured next to my usual. This serum is significantly more runny compared to my usual. Either way, I used this serum faithfully for a little over 2 months. I gave it a solid go. I do not find it as effective as the other brand, which is funny because when is the cheaper version ever the one you prefer?!I have combo skin, this was the only step I changed & I found it made my skin look/feel far more oily. Like by afternoon, I was shining pretty bright! Which is not typical for me. Other than that, it did absolutely nothing for my pores or a slight dark spot I have from the sun. My pores felt more clogged than ever. I'm not sure if it's just my skin but this product did not agree with me.
