The Journey of Using The Ordinary Products: Niacinamide and Hyaluronic Acid


The Ordinary has gained immense popularity for its skincare products, especially the Niacinamide and Hyaluronic Acid serums. These products have received raving reviews on platforms like YouTube, TikTok, and Pinterest. However, it is important to manage expectations, as not everyone experiences the same results. In this article, we will take a closer look at the benefits of these serums, how to use them correctly, and the author's personal experience after using them for 40 days.

Understanding the Ordinary Products

The Ordinary's Niacinamide and Hyaluronic Acid serums are both highly regarded for their ability to improve skin texture and reduce blemishes. Niacinamide is a high-strength vitamin and mineral formula that targets skin blemishes and congestion. It works by minimizing enlarged pores, improving uneven skin tone, reducing fine lines and wrinkles, and strengthening the skin's surface.

On the other hand, Hyaluronic Acid is a hydration support formula with ultra-pure vegan hyaluronic acid. It acts as a humectant, retaining water within the skin and providing lasting hydration. It plumps the skin and revitalizes the outer surface layers, leaving it soft, smooth, and radiantly hydrated.

The Benefits of Niacinamide

Niacinamide offers a range of benefits for the skin. Apart from reducing skin blemishes and congestion, it also helps in minimizing enlarged pores and tightening the skin. Additionally, it improves uneven skin tone, softens fine lines and wrinkles, and diminishes dullness. Niacinamide is safe to use daily, either in the morning or at night. However, there is a slight possibility of experiencing irritation or redness, so it is important to do proper research and adjust usage accordingly.

How to Use Niacinamide

To incorporate Niacinamide into your skincare routine, start by cleansing your face and patting it dry. Apply a few drops of the serum onto your palm or directly onto your face, and gently pat it into the skin. It is recommended to follow up with a moisturizer and sunscreen, especially in the morning.

Initial Reactions and Adjustments

During the first week of using the Niacinamide serum, the author experienced some redness on their cheeks and nose. However, there was no itchiness or burning sensation, which indicated that they were not allergic to the product. They noticed that their skin texture improved as all the bumps started surfacing, but the redness subsided by the end of the week.

Week 1 Update

After one week of using the Niacinamide serum, the author observed no significant changes in pore size. However, their skin felt smoother, and the redness had reduced. The author reasoned that the initial breakout and redness might be attributed to the concept of skin purging, as explained in a video by Dr. Nina Desai and Susan Yara. Purging occurs when using active ingredients that accelerate skin renewal, causing impurities to surface.

Week 2 Update

By the end of the second week, the author noticed a considerable reduction in red blotches and spots on their face. The skin appeared clearer, especially when looking at it through a camera screen. However, the author did not witness a remarkable change in pore size, which left them slightly disappointed. They made adjustments to their skincare routine, including the application of hyaluronic acid on damp skin and avoiding morning cleansing.

Week 3 Update

During the third week, the author experienced peeling on their nose, which required them to layer the routine with a green tea balancing cream from Innisfree. Although the dry skin cleared up quickly, the author did not see significant improvements in pore reduction. However, their skin's oiliness was completely under control.

Final Assessment

After 40 days of using the Niacinamide and Hyaluronic Acid serums, the author observed positive changes in their skin. The skin became softer, and there was a significant reduction in oil production. However, the author felt that the pore reduction was not as quick as expected, possibly due to overhyped expectations influenced by internet reviews. The author concluded that both serums are worth trying, especially for those with oily and combination skin.


In conclusion, the Ordinary's Niacinamide and Hyaluronic Acid serums have showcased positive effects in improving skin texture, reducing blemishes, and controlling oil production. It is important to be patient and adjust the skincare routine according to individual needs. While results may vary, these serums offer visible improvements and are worth considering for achieving healthier and hydrated skin.
