Niacinamide is a multi-functional superstar ingredient that can normalize pores, soothe acne-prone skin, improve the skin barrier and even lighten hyperpigmentation. This formula contains a whopping 10%, ideal to improve the appearance of acne and blemish-prone skin.
To further enhance Niacinamide's already awesome problem solving skills, we have included Zinc PCA and Sarcosine, both known to help enlarged pores, oiliness and blemishes.
Who is it for?
how to use it?
Apply a few drops to the face after cleansing (+ toning and exfoliating), but before using emulsions and/or creams. Can be used either in the AM and/or PM.
It can be used on its own, or you can add it to another product as a Niacinamide Booster e.g. your moisturizer or our HA 5 Serums - just put a few drops of each into your palm or apply a few drops of them directly to your face at the same time and pat them on together. Please do not add B-Bomb directly to acids, such as exfoliating acids or pure Vitamin C - you can use them in the same routine together layered on top of each other, but they don't mix well directly (e.g. in your palm).
Shelf life: 2 years from production (unopened), 6 months PAO (period after opening)
Ingredients & Research
Niacinamide (10%) – A multi-functional superstar that can normalize pores, soothe acne prone skin, improve the skin barrier and lighten hyperpigmentation.
Zinc PCA – A combination of antibacterial and sebum normalizing Zinc with the humectant molecule found in the skin called PCA (stands for pyrrolidone carboxylic acid). Zinc PCA has the property of both, meaning it is a gentle, non-drying ingredient known to help acne-prone and oily skin.
Sarcosine – An amino-acid derived ingredient that works as a so called 5α-reductase inhibitor helping to normalize oil-production and pore size.

Honestly G&G never goes wrong, but the niacinamide serum is particularly impressive cause most other serums so often have issues with texture, absorption or peeling. This just goes on like a dream and mixes flawlessly with any other product. I recommend it to everyone cause it’s hard for anyone not to benefit in some way. Will repurchase forever.
I find this product has very light, fluid texture that absorbs into the sink easily. My sensitive skin experienced no irritation, unlike some other high % niacinamide products out there that I have tried. Highly recommend for normal, oily and acne prone skin. Because it absorbs so quickly, it can also be layered nicely with other products to suit additional skin concerns.
It really helps regulate sebum and blemishes. I like the combination in the evening with the Porefectly Clear serum and it works really well, my skin texture is much more refined.
I have tried too many products for my acne prone skin and this serum has been definitely the game changer for me. I highly recommend it to everyone who struggles with pimples.
I've tried the serum for around a month now and I have noticed an increase in breakouts. I think this may be due to irritation due to the high niacinamide concentration (I try to always leave a lot of spacing between trying new products to isolate the effects). I am leaving 2 stars because I am not 100% certain it is caused by the niacinamide (skincare is very complex), but I am leaving a low rating because I do not see any evidence for why the serum needs to be 10%. Geek and Gorgeous does an excellent job with their other products in providing well-researched formulations... however, I cannot find a single scientific study supporting the use of 10% vs 4-5% niacinamide concentration! Why not reduce the concentration? You could even consider adding in other positive ingredients as well.
