Results without the irritation!
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 thatâs 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 itâs 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 havenât 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 itâs definitely a product worth incorporating into your routine!

Great value
The COSRX Niacinamide 15% Face Serum is an impressive addition to any skincare routine, particularly for those dealing with issues like hyperpigmentation, large pores, and uneven skin tone. Here’s a detailed review of its features and performance:**Ingredients and Formula**:The serum boasts a potent concentration of 15% niacinamide, a form of vitamin B3 known for its brightening and anti-inflammatory properties. Additionally, the formula includes other beneficial ingredients such as panthenol (pro-vitamin B5) for hydration, and allantoin to soothe the skin. The serum is free from parabens, sulfates, and artificial fragrances, making it suitable for sensitive skin.**Texture and Application**:The texture of the serum is lightweight and slightly viscous, which allows for easy application without feeling greasy or sticky. It absorbs quickly into the skin, making it convenient for both morning and evening routines. The dropper bottle ensures precise dispensing, minimizing product waste.**Performance**:Users report noticeable improvements in skin texture and tone after consistent use. The high concentration of niacinamide helps to reduce the appearance of dark spots and redness, leading to a more even complexion. Many have also observed a reduction in the size of their pores and an overall smoother skin surface.**Results**:With regular application, typically over a few weeks, the serum effectively diminishes hyperpigmentation and brightens the skin. It also aids in controlling excess sebum production, which can be beneficial for those with oily or acne-prone skin. The hydrating elements in the serum help maintain the skin’s moisture barrier, preventing dryness and irritation.**Packaging**:The product comes in a sleek, minimalist bottle with a dropper for easy and hygienic application. The opaque bottle design protects the serum from light exposure, preserving the integrity of the ingredients.**Pros**:- High concentration of niacinamide- Lightweight, non-greasy formula- Noticeable improvements in skin texture and tone- Suitable for sensitive skin- Free from harmful additives**Cons**:- The 15% niacinamide concentration may be too potent for some, potentially causing initial irritation for sensitive skin types. It’s advisable to perform a patch test before incorporating it fully into your routine.**Conclusion**:The COSRX Niacinamide 15% Face Serum is a powerful and effective solution for those looking to tackle hyperpigmentation, uneven skin tone, and enlarged pores. Its well-formulated blend of ingredients offers visible results without compromising on skin hydration or comfort. Despite its potency, with proper usage and gradual introduction into a skincare routine, it can become a staple for achieving clearer, brighter skin.

Love the Results, But Please Offer a Full 1 oz Bottle
Iâve been using this Cosrx niacinamide serum as part of my evening skincare routine, right before applying tretinoin, and Iâm really happy with the results so far. Itâs lightweight, absorbs quickly, and doesnât leave any sticky residueâhuge plus! Iâve noticed an improvement in my overall complexion and my pores appear smaller and more refined.I definitely plan to keep using this and usually repurchase when itâs on sale. My only suggestion is that it should come in a full 1 oz bottle instead of just 0.67 ozâespecially for those of us who use it daily. Otherwise, itâs a solid addition to my skincare lineup.

Strong formula
While I love Cosrx, this niacinamide may be a little too strong for my rosacea-prone skin. My skin does okay with it but there is a little stinging.This will be one Cosrx product I likely won’t reorder. I instead use Beauty of Joseon’s niacinamide with propolis–it doesn’t irritate my skin and it feels wonderful going on.Also, this is less than an ounce and my BOJ is 1.01 ounces and costs less. Though, Cosrx is not pricey at all – very reasonable prices. If it didn’t sting my face, I’d probably reorder to use alternate days with BOJ.
