TIAM Vita B3 Source Review | Reduces Blemishes

Tiam Global Vita B3 Source Review

Tiam Vita B3 Source

My first K-beauty skincare product! You might have not seen me talking much about K-Beauty skincare trend on the blog but I finally joined the bandwagon last month. Tiam, a Korean beauty brand, sent me their Vita B3 Source to try and review around a month and a half ago.

Today I’ll specifically talk about the Tiam Vita B3 Source which is basically a mixture of 10% Niacinamide and 2% Arbutin solution. And it targets dark spots and uneven skin tone, thereby giving you a brighter complexion.

Niacinamide is a form of Vitamin B3 which improves skin’s barrier function and also controls melanin production which gives brighter skin. It also helps to regulate oil-production so it’s great for people with oily skin.

A less irritating alternative to hydroquinone, Arbutin, is a natural ingredient extracted from cowberry. It prevents the synthesis of melanin and works on reducing pigmentation. This serum has Beta Arbutin. Now, what’s that?! Refer to this handy chart below to know more about Alpha and Beta Arbutin.

Does that mean the Tiam Vita B3 Source is ineffective due to the presence of Beta Arbutin? Yes and No. From what I can understand it that it also has a very high concentration of Niacinamide so that combination might have increased the effectiveness of the product.

It works in a 2-step process in which Arbutin inhibits synthesis of melanin and Niacinamide prevents packets of melanin from reaching the skin’s surface.

My Thoughts on Tiam Vita B3 Source

This serum combines two of the best-known ingredients that are known to work on blemishes and give even-toned skin. Being a brown girl with acne-prone skin, I do have to deal with the marks my acne leave. So, this Vita B3 serum was definitely something I could use to target my skin concerns.

If you need to know, how I get rid of the stubborn acne within just 2 days the you should check out The Ordinary 2% Salicylic acid solution and see my acne-progress with it. 

Not just acne, ageing, pollution, stress and sun exposure also leaves the skin looking dull and lifeless. This is why it is important to use brightening ingredients in your routine to bring back life to your skin. However, products aren’t everything and a healthy lifestyle is very important to counter these problems.


The Tiam Vita B3 serum comes in a dark brown, glass bottle that has a dropper to dispense the product. I have The Ordinary’s Niacinamide solution and it came in a clear glass bottle. So I’m guessing that the dark coloured bottle here is to help with the stability of “Arbutin” used here. (Refer to the comparison chart above). What do you guys think? The glass bottle is slightly heavy and you have to be careful with it while travelling.

Texture & Smell

The serum is a clear solution that’s slightly more viscous than water. Again, on comparing with The Ordinary’s Niacinamide + Zinc Solution, this one’s more watery thin and runny. And the Tiam B3 source doesn’t have any smell to it.

The comparison is not very fair because the second ingredient in both the products is different. But since the primary ingredient is the same, I thought it might help some people form a decision.


After cleansing and toning, I take 2 drops and apply this all over my face. Then add another drop just to pat it on the acne scars and the area around my mouth that has some discolouration. I do this twice a day, morning and night and follow it up with a moisturizer and sunscreen (in the morning). It gets absorbed very fast and leaves a dewy finish. You wouldn’t experience any oiliness and sticky/ heavy feeling on applying it.

How Does the Tiam Vita B3 Source Work?

I started using this in the second week of February and I have also attached pictures of my 2-week journey with this product. I wanted to test it out and see how it works on fading my newly-gifted acne scars. The first picture shows day 1, with the brown marks showing through.

A week later, I noticed some reduction in the brown spots, they became lighter than before but didn’t disappear completely.

The last one is week 2 where the dark spots have reduced A LOT. There’s no much left but they have still not disappeared.

Us brown girls face an additional problem with acne scars when the deep brown spots just refuse to leave. And this serum worked great on fading those.

I’ll repeat, it DID NOT eliminate them completely in two weeks.

Overall, my skin looks healthy and dewy. Another point to note is, I have been exfoliating my face 2-3 times a week with The Ordinary Glycolic Acid which is another product that works on scars and uneven skin tone. So both the Tiam Vita B3 Source and AHA worked in conjunction to even out my complexion.

It’s been over a month and I am still using this serum. I have at least 80% of the product left which shows how long it will last you. Even if you don’t want to buy this particular product, you can use any Niacinamide or Alpha Arbutin based serum from a good brand to help with blemishes.

Comparison between The Ordinary & Tiam

The Ordinary Niacinamide 10%+Zinc 1% targets scars, uneven skin tone and sebum/ oil-production (Thanks to zinc!). While the Tiam Vita B3 Source with Niacinamide 10% + Arbutin 2% is meant only for scars, blemishes and uneven skin tone. So you can make the decision depending on what your skin needs. Also, The Ordinary one feels like it’s sitting on my skin which might bother people.

The price tag is pretty similar with The Ordinary one retailing for approx $10 and Tiam for $18 but Tiam is on sale on jolse.com and goes as low as $13-14. And you also get a lot of freebies when you order from that site.

Why You Should Buy Tiam Vita B3 Source?

  • Evens out skin tone
  • Works on reducing acne scars
  • Very lightweight
  • Didn’t cause skin irritation
  • Cruelty-Free
  • Affordable

Why You Should Avoid Tiam Vita B3 Source?

  • Couldn’t find a reason. It does what it claims but don’t expect dramatic results overnight.

  1. I learned a lot from this! Great timing for summer as I get very dark in the sun believe it or not. I also suffer from blemishes pretty frequently. I love The Ordinary but this product seems very effective. Thanks for the info!

      You’re welcome! I tan pretty easily in summer so an anti-oxidant definitely helps 🙂 And of course slathering on some spf.

    Great review! I have some blemishes that I would love to get rid of, so I’ll have to look more into this since I can truly see your results so far.

      It definitely works on that. However, if korean beauty brands aren’t accessible to you, The Ordinary’s Niacinamide+Zinc works pretty much the same 🙂 Hope this helped!
