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.

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

If you have oily skin, BUY THIS.
Worth the hype! Surprised it’s not more expensive than it is. I have a very oily T-zone, and this product eliminates the oiliness entirely. I use other products, but I noticed that when this runs out, my T-zone gets very oily again in a few days, so it’s definitely this product that cures it. If you have an oily skin type this is definitely for you! So glad I discovered it! I’ve been using it for around a year now and it’s great quality!

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.

So good
I’ve been using this Good Molecules Niacinamide Serum as part of my daily skincare routine, and I’m very happy with the results. The texture is lightweight, absorbs quickly, and doesn’t feel greasy at all. After a few weeks, my skin looks more even, smoother, and my pores appear smaller.I also appreciate that it’s gentle and doesn’t irritate my sensitive skin. It layers well with other products and feels simple but effective, without unnecessary ingredients.Pros:✔️ Lightweight and fast-absorbing✔️ Helps with uneven skin tone and pores✔️ Gentle on sensitive skin✔️ Affordable and effectiveI would definitely repurchase and recommend it!

I order more everytime I run out! My favorite serum to use in the morning. So lightweight and moisturizing! Serves as a great base after a toner and before applying SPF.

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.

Es un buen producto, mi experiencia como persona con acné y piel grasa sensible, puedo decir que me a ayudado a calmar y a disminuir los brotes, también a controlar la oleosidad.Cómo cualquier producto se debe general tolerancia, como por ejemplo 2 días a la semana y si bien tu piel no es tan sensible puedes ocuparlo un día si y un día no. Ya llevo tiempo usándolo así que yo lo aplicó todos los días por la noche y durante el día una vitamina C (por manchas de los brotes) y protector solar.
