Tiam Vita B3 Source It has a fairly high Niacinamide content, namely 10%. The texture is watery, very light on the skin. No stickiness and absorbs quickly. Have been using it for 3 weeks and I get satisfactory results. My skin became brighter and smoother.

A fast absorbent unscented serum, clear as water but a bit thicker in texture. Definitely a hydrating and moisturizing formula due to its Sodium hyaluronate content ( a form of hyaluronic acid that can enter the deep layers of the skin to reduce dryness and wrinkles) which by the way is excellent for all skin types. You may find it sticky but the stickiness gradually goes away as the product fully sips into the skin.

The texture of this serum is thick, but i love it. The serum giving me a brighten skin with moisturize effect.

I really like the texture and the fact that the serum isn’t sticky or greasy. I typically use it in the evenings, because I have separate vitamin C products to finish off in the mornings. I am noticing better (aka smaller) looking pores and less skin sebum.

So far my skin is loving it. i use it every two days in a week .

Moreover, it also helps with my dull skin

After just a few weeks of use, I have noticed a dramatic improvement in my skin tone and texture. The 10% niacinamide has helped to reduce the appearance of dark spots and even out my skin tone. Additionally, it has helped to minimize discoloration and give my complexion a more radiant look. I also love that it helps to reduce excessive sebum production and address breakouts. It is so easy to use - I just apply 2-3 drops evenly on my face after toner and reapply on areas of concern, then gently tap until it is fully absorbed. Finally, I make sure to apply sunscreen after to protect my skin from the sun. I highly recommend the Tiam Vita B3 Source skin brightening serum for anyone looking to brighten and even out their skin tone!

I use this serum after toner and before moisturizer, and I often use it at night.  So far, my skin looks brighter. However, I think it takes longer to completely fade the dark spots.

It moisturizes my skin which is super dry.

Vita B3 source serum contain niacinamide to help brighten dark spots, minimize pores and control sebum production. This also has allantoin to help soothe irritated skin. This serum has a slightly viscous texture and is slightly tacky but dries down quickly

It is such a good product IT IS A STEAL! It is cheap however, you get more than what u expect

Has unscented watery with slight slimy texture. The slimy texture makes it easier to apply. Becomes tacky-greasy when absorbed & leaves dewy finish. Yet despite the greasy-tacky feeling, it does feel lightweight. The brightening effect starts to pay off within just 2 weeks. My skin is much more hydrated, glowy, & bright. The slimy texture seemed to help in reducing fine lines and get that plump skin. Though this somehow clogged my pores, I just use deep cleansers & lightweight creams. For a price of less than 10 USD, this is such a great skincare investment.

Es un muy buen producto me gusta mucho la textura y como se siente en la piel

Don’t see much of a difference using this but still giving it a shot. On my second bottle now.
