ROLANYIN Niacinamide 10% + Zinc 1% Facial Serum for Oil Control and Pore Minimizing Blemish Treatment Hydrating Soothing Anti Aging and Nourishing Formula Skin Care

Tried another brand, this one is definitely superior. Improves skin and immune system health, and helps fight staph when applied around an infected area.

I use every night and everyday it’s perfect

I had some dark spots after acne, after using this product dark spots faded but didn't disappear, still like the result.

Oh, my - I did some research on niacinamide and the skin - the list of possible benefits is amazing. Niacinamide (also called nicotinamide) is a type of vitamin B-3. Using it on your skin may help treat acne and eczema, may reduce inflammation and redness, and possibly minimize fine lines and wrinkles. Yay, I'm all for that! More research is needed, however. And noticeable improvements may take 4 weeks or more, although there's no exact time line, according to what information I found. It's recommended to use this serum before moisturizing. It is a 10% solution , so you don't have to lather it on, as 5% is suggested as a possibly effective concentration, which means the bottle should last for a decent period of time. If you have sensitive skin, they recommend a patch test. Put a small dab on your forearm, massage it in, and wait 24 hours, and check for any side effects. After that, you are good to go. It feels good on my skin, hoping for some great results. :-)

I love it .
