Best niacinamide serum I’ve ever used!
This brand is AMAZING! This is my favorite product. I use a couple of things from this brand. Finally, affordable skincare that works! To think of the money I’ve wasted on expensive skincare that didn’t compare to this! This feels so good applied to the skin. It has changed my skin so much when applied with the other products I use. Skin tone: even, pores: practically nonexistent, acne scars: gone, and more. I would bathe in this if I could! I only buy the big bottles now. Grab a bottle along with their hyaluronic acid for instance hydration, smoothing of fine lines and wrinkles, and plumpness of the skin. That’s on top of the other benefits I’ve listed above.

The Holy Grail Niacinamide!
If I could give this Good Molecules Niacinamide Serum six stars, I absolutely would. This isn’t just a serum; it is a skin transformer and a non-negotiable staple in my routine.The 10% Niacinamide concentration is the perfect sweet spot—it’s powerful enough to deliver dramatic results yet remains gentle and ultra-hydrating. I have struggled with stubborn texture, visible pores, and frequent breakouts, and this product addressed every single one of those issues.Within weeks, my skin tone became visibly more even and bright. The most impressive change was how much it helped with congestion; my breakouts have decreased significantly, and the frustrating red marks left behind fade much faster. The serum is lightweight, absorbs instantly without any stickiness, and layers beautifully under moisturizer and sunscreen.If you are looking to target acne, large pores, dullness, or uneven texture, stop searching and buy this. It is incredibly effective, affordable, and easily the best investment I’ve made for my skin health

Satisfied
It has the consistency of glycerine and dries very quickly. It doesn’t have any scent but slightly burns when you start sweating lots. Been using for weeks now and I have noticed a change in my acne. It does work as well as advertised and you don’t need to use a lot either. Definitely worth the money.

Sensitive Skin Serum for Hyperpigmentation, Texture, Pores & Acne Marks.
I’ve been buying different skincare products because I really want to improve the way my skin looks and feels. My skin type is combination, with a history of acne, some acne marks, enlarged pores (especially on my nose and cheeks), a dull and slightly dry tone, occasional sensitivity, a light expression line on my forehead, and sometimes dry patches. As you can see, I have quite a few concerns, so I have to be careful with the products I choose.💬 I bought this niacinamide serum to help improve my skin’s texture and reduce enlarged pores. It’s been helping a lot with both my acne marks and the appearance of pores. What I love most is that it works effectively without causing any burning or irritation, which means it’s perfect for sensitive skin. My skin feels smoother, more even, and looks healthier overall.

The serum is affordable, but I didn’t see any results
It’s a product you need to use consistently. You won’t see very visible results the first month, but it does help your face look healthier. I wasn’t completely convinced, though. I wouldn’t recommend it if you have acne. It’s lightweight, absorbs well into the skin, It has no smell, it moisturizes the skin and you can feel the softness. Honestly, it’s not bad for the price.

Love, love, love
I’m a repeat customer of Good Molecules. I love their Niacinamide Serum & the Hyaluronic Acid. They have been in my daily skin routine for months. My skin is so so soft, hydrated and never looked better.

My holy grail
On my 4/5 bottle. I have been using this for maybe 2 years now and my skin is smooth and soft. It’s one of my holy grail. I have oily skin so it reduces that and minimizes my pores for sure. It’s good product for the price and is easy to apply.

Good product, Love it!
Good product. It works gentle, it removes dark spots from my skin, it removes micro wrinkles. Makes skin shiny and younger looking. I put it even on my hands from dark spots. Yes, I would recommend this product and will buy it again.

Sowohl ich im Gesicht als auch mein Freund an der Brust (da ich mich beim Schlafen angeschmiegt habe) haben davon richtig schlimmen Ausschlag bekommen. Fehlkauf!

Just purchased another two bottles in the larger size. I was sceptical at first didn’t think it would work on my large pores but they’ve actually shrunk and smoothed out. Really impressed. Definitely recommend. Recommend taking before and after photos as I wish I had.
