Welcome back to Halsadiya Beauty Blog 💃🏾

Y’all must have definitely come across Deciem’s The Ordinary skincare range. The brand “The Ordinary” is described as “an evolving collection of treatments offering familiar, effective clinical technologies positioned to raise pricing and communication integrity in skincare”. I just had to lay my hands on any of the skincare range.

The first item I tried was one I was looking forward to and was so hyped by many and that’s is the Niacinamide 10% + Zinc 1% serum. I was a bit skeptical because the price was budget friendly. I did want to love this serum and wanted it to work for my skin; after reading couple of reviews and first impressions, I thought that this would be a great product.
However, I was left a little disappointed as the serum just didn’t quite do what it promised to do for my skin.


Niacinamide is a Vitamin; Vitamin B3, also called Vitamin PP. In cosmetics, it belongs to the category of antioxidants
The Niacinamide Serum is made up of a high concentration (10%) of Niacinamide, and additional Zinc (1%). The formulation is oil-free, alcohol-free and silicone-free.

Vitamin B3 is known to reduce the appearance of skin blemishes and congestion, whilst balancing your natural sebum levels for a shine-free complexion. It improves the skin’s barrier function, preventing the skin from losing water and protecting it from pollutants and irritants, making it particularly gentle on skin. It improves skin texture and smoothness, whilst calming any breakouts, reducing the size of the pores and excess oils. It also helps to decrease pimples and blackheads. It has a brightening effect on hyperpigmentation and dark spots.

Zinc is an anti-inflammatory, commonly used to treat burns and scars and fight against free radicals. It also encourages collagen production to reduce the appearance of wrinkles and fine lines.

Niacinamide (Vitamin B3) is indicated to reduce the appearance of skin blemishes and congestion. A high 10% concentration of this vitamin is supported in the formula by zinc salt of pyrrolidone carboxylic acid to balance visible aspects of sebum activity.

CONTRAINDICATIONS: If topical Vitamin C is used as part of skincare, it should be applied at alternate times with this formula (ideally Vitamin C in the PM and this formula in the AM). Otherwise, Niacinamide can affect integrity of pure-form Vitamin C (L-Ascorbic Acid).

NOTES: While Niacinamide and Zinc PCA reduce the look of blemishes and balance visible sebum activity, neither is a treatment for acne. For persistent acne-related conditions, we recommend the use of Benzoyl Peroxide and/or Retinoic Acid. DECIEM doesn’t recommend ongoing use of BHA such as Salicylic Acid for persistent blemishes. For temporary improvement in appearance of blemishes, Salicylic Acid would help. This formulation can be used alongside acne treatments if desired for added visible skin benefits.
Independent studies suggest Niacinamide is also an effective ingredient for brightening skin tone


The Niacinamide serum comes in a white card box, inside the cardbox is the serum in a glass bottle with a dropper. It’s 30ml in size and fragrance free.


The serum is a slightly sticky gel. A pea size (1/4th of the dropper) of the serum is fine for one application. When you apply too much serum, it tends to foam a little on skin and takes longer time to absorb.

It’s a quite simple formula, it’s water based, alcohol-free, silicone-free, oil-free, nut-free, cruelty-free and vegan. The main ingredients are niacinamide concentrate at 10% and zinc (1%), a mineral known for its purifying effect.

You can apply the serum twice a day, morning and night if you want to.
I prefer using it in the morning alone before applying my moisturizer, so I have chance to apply my vitamin C serum at night. Tho, I’ve used the serum at night alone before applying my night cream and also twice a day.

I was really excited trying out this product. I’ve heard and read couple of raves about the benefits of Niacinamide and it’s one of those skincare ingredients that I have always wanted to try alone. I was also fascinated about the Niacinamide serum as I have been all about Korean skincare and most products that I’ve used with Niacinamide made my skin refreshed and balanced.
It was quite disappointing I didn’t see the same results with The Ordinary Niacinamide 10% + Zinc 1%. I love the texture and the “priming” effect it has as it did regulate my sebum.

This product claim to be a high strength vitamin and mineral blemish formula, but I did not feel improvement in terms of reducing blemish, improving my skin texture and minimizing pores. For the price however, I am not complaining as I am quite not convinced with the serum. Price range varies from NGN 5000 – 6000

My experience with The Ordinary Niacinamide 10% + Zinc 1% has not been overly negative nor has it shown groundbreaking results either. I used this serum continuously for over 2 months and in the fourth week, I noticed it did regulate my sebum, however I can’t say the same for reducing blemish, hyperpigmentation and minimizing pores.
I did expect more from the serum and tried continuous usage as I wanted it to work out for skin. I have stopped using the serum, not because it did anything bad to my skin but more to the fact that the serum didn’t really work for me. I do have other products with Niacinamide that works effectively. And I will not be repurchasing but will love to try out other serums like the Mandelic acid from the brand.

Have you used the Niacinamide 10% + Zinc 1% serum? Have you tried any product in The Ordinary range?? What are your thoughts???
I will love to hear your experience in the comments below
