Results without the irritation!

Reviewed in the United States on April 15, 2024

Size: 0.67 Fl Oz (Pack of 1)Verified Purchase

This product I can honestly say has been a remarkable addition to my skincare routine, particularly in addressing my longstanding battle with hyperpigmentation and uneven texture that comes with maturing skin. Its high concentration of niacinamide, known for its skin brightening and texture-improving properties, has genuinely started to transform my complexion. Sense I only apply once per day that’s pretty impressive in my book.
From first use, the serum impressed me with its lightweight texture that absorbs seamlessly into the skin, leaving no sticky residue. This feature is particularly important to me, as it allows for easy layering with other products, and sense I apply daily at night it’s an important feature.
One of the most noteworthy outcomes I've experienced since incorporating this serum into my regimen has been the visible reduction in dark spots and overall skin discoloration. My hyperpigmentation has gradually become less pronounced, revealing a more even skin tone that I've been striving to achieve for years. Additionally, the serum has effectively minimized the appearance of enlarged pores and provided relief from redness, enhancing my skin's overall clarity and texture. I haven’t noticed a difference in the overall moisture or hydration of my skin but it was never my intention anyway.
What sets this product apart for me is not only its efficacy but also its gentle formula. Despite the high concentration of niacinamide, my sensitive skin has tolerated it well without any signs of irritation or dryness. This is a significant advantage, as many potent skincare treatments can be too harsh for delicate skin..
After consistent use, the improvements in my skin are undeniable. While patience is necessary to see full results, this serum has proven to be a powerful ally in reducing hyperpigmentation and enhancing my skin's overall health. I would highly recommend giving it a go if your looking to reverse hyperpigmentation or smooth out pores it’s definitely a product worth incorporating into your routine!

Reviewed in the United States on February 26, 2024

Size: 0.67 Fl Oz (Pack of 1)Verified Purchase

⭐⭐⭐⭐⭐

I am absolutely thrilled with the Niacinamide 15% Face Serum and its transformative effects on my skin. This serum has become an integral part of my skincare routine, delivering remarkable results that have exceeded my expectations.

First and foremost, the concentration of Niacinamide at 15% is a game-changer. It has worked wonders in addressing various skin concerns. I've noticed a significant reduction in the appearance of pores and an overall improvement in the texture and tone of my skin. The serum has a lightweight and easily absorbable consistency, making it a pleasure to apply.

The brightening effect of this serum is truly impressive. Over time, I've observed a more radiant and even complexion. Dark spots and hyperpigmentation have visibly faded, leaving my skin looking more youthful and vibrant. It's like a boost of radiance in a bottle.

One of the standout features is its compatibility with other skincare products. I've seamlessly incorporated it into my existing routine, and it plays well with other serums and moisturizers. The non-greasy formula ensures that my skin feels hydrated without any heaviness.

The long-lasting hydration provided by the Niacinamide 15% Face Serum is another notable benefit. It has significantly improved the moisture balance of my skin, reducing dryness and promoting a supple and plump appearance.

I appreciate the attention to detail in the packaging – the airtight pump dispenser not only keeps the product fresh but also ensures precise and mess-free application. It's evident that the manufacturers prioritize both the effectiveness of the serum and the user experience.

In conclusion, the Niacinamide 15% Face Serum has become my go-to solution for achieving clear, radiant, and healthy skin. Its potent formulation, visible results, and user-friendly design make it a standout product in the world of skincare. I highly recommend it to anyone looking to elevate their skincare routine and unlock the full potential of their complexion.

Game changer for oily skin!

Reviewed in the United Kingdom on April 17, 2024

Size: 0.67 Fl Oz (Pack of 1)Verified Purchase

Within days of using this my pores are less visible & my t zone is far less oily. Post break out marks have reduced dramatically improving the overall appearance of my skin, which has blown my mind! I use this on a morning after the snail mucin essence & before a moisturiser. You only need a small amount. It spreads well across the skin & dries very quickly. Hugely recommend this for combination to oily skin types.
