This is best hyperpigmentation serum there is. I love it I am stuck on it.

I was looking for something to replace the ordinary's niacinamide + zinc because it was a bit too drying for me even though I have oily skin. I'm glad I came across this because none of the issues I had with the ordinary's product were present with Tiam's Vita B3 Source. There's no smell, it sinks into the skin, it doesn't pill, and it's not drying at all. It has also helped with lightening acne scars and hyperpigmentation.

First time trying out this brand, heard great reviews about it.

I always buy this product whenever it is on sale. I love it and it makes my skin brighter overnight! Great for hyperpigmentation!

A beautiful serum for hyperpigmentation, you just have to be careful while using

Me gusta la textura ligera que tiene, funciona muy bien y con el tiempo se ven los resultados en las manchas, recomiendo usarlo con cuidado cuando se incluye la primera vez ya que no todo el mundo tolera muy bien porcentajes altos de niacinamida

This underrated niacinamide serum has surely been my latest fave. I have been using TO niacinamide for a year I had a love - hate relationship with it as it sometimes sting my face. But with tiam, it was a pleasant experience for me. Didn't see a big difference right away but I used 3/4 and now I can see a big difference to an overall brightness of my skin and the oilynessnon Mt tone is well under control. I will definitely repurchase.

Me ha ayudado con mis poros, se ven más pequeños y mi piel ya no está tan grasosa como antes. COn respecto a las manchas de acné, he notado un ligero cambio. Quedo muy satisfecha con el control de la producción de sebo.

The best product ever, I recommend everyone to buy it

I use it 3 times per week but it really works for anti aging.... gonna continue until the last drop of the bottle

will update once i used this product. heard good review about this but i am glade that i got in a very good price

Me encanta!! realmente me funciona muy bien

Excelente producto, me encantó la combinación de activos

it brightens my skintone and this is my second perchase.

Brightens my complexion so much - my new holy grail

It's so good for acne scar, recommend this❤️

The bottle was actually larger than I thought it would be. I absolutely love this product because it has evened out my skin tone and does not burn my skin at all when using it. Be sure to keep it in a cool dry area away from the sun to maintain clear color.

I really love this product, makes my skin so soft.

This is probably the best niacinamide serum I have ever tried. It doesn’t make my skin dry despite the high concentration of niacinamide (10%). It layers well with other skincare products unlike other niacinamide serum from other brands.

I love this serum! I used to use The Ordinary’s Niacinamide serum but hated it because of how it pills. I researched for an alternative and found Tiam Vita B3 Source. It has the same percentage of Niacinamide (10%) as The Ordinary’s but it’s even better because of the 2% Arbutin. The best part is that it layers well with other skincare products! I love this and this has replaced all niacinamide serums in my skincare shelf.

It really helped my oily skin

Vey good totch and the effect need time to apper

I heard it may cause some purging but I'm yet to try personally

I buy it 2 times and use at night

great after hyperpigmentation perfect for scars

Great Niacinamide serum, it is not harsh for my sensitive skin.

Great serum that has Niacinamide help with oil.
