Magic rednesss/acne/pore eraser for my fair skin!
I am in LOVE with this serum. It just works like straight up magic on my face and addresses so many things all at once with absolutely zero irritation at all. I have fair-light combination skin that, thanks to my irish ancestors, makes any blemish and any leftover healing spots a bright red glaringl...

It's an okay serum
Received for free courtesy of influenster and cosrx for my honest review. The packaging of the rx line is super simplistic and minimalistic, like the black/white look. This bottle was short and round. The Niacinamide 15 is a concentrated serum that has 15% Niacinamide. The serum is nice. Its almost ...

Completely Changed my Skin in 1 Month
I use this every evening before bed and before moisturizer. My skin is glowing and plump and bright. It looks so much better than a month ago. My pores are tighter and I also never get acne now.
Not impressed
I bought this to reduce my redness. My skin is prone to subclinical rosacea, so I don't have the traditional flare ups you think of with the condition, I just have a condtant baseline of redness all over with the occasional increase in redness due to heat/cold. This product did nothing for my redness. Not even after weeks of consistent use. I also did not see any reduction in acne inflammation and redness. So I can't recommend this product. Especially for the price. In addition, the product is sticky for a long while as it soaks in, and it did cause breakouts if I applied too much of it. 3-4 drops is enough for my face. It does play well with other products though.
Oil Slick ➡️ Matte-tastic!
Used this before bed last night and woke up to a matte face! I'm in my 40s and there hasn't been a day since puberty that I didnt wake up looking like an oil slick… until now! Hoping it helps my sebaceous hyperplasia too! That's what another review mentioned, which was why I bought it. 🤞🏼Excessively oily girlies - this is your solution!
Great product
Great product for matire skin. The packaging needs improvement. The suction doesnt get any product out so i have to pour directly from the bottle.
thought niacinamide wasnt for me until i tried this one..
I notice a difference in my acne overnight
