COSRX15% Niacinamide Face Serum, 0.67 fl oz, Pore Minimizer Serum for Face, Even Skin Tone, Korean Skin Care

I love it, way too expensive for less than an ounce of product, but worth the financially questionable decision. It is very calming and hydrating, absolutely does visibly reduce pores, oiliness, and redness after a few weeks. Works great under makeup, not sticky or pilly at all. As with all niacinamide it only works while you are using it, if you stop, the results do not continue, so take note of that, but it's to be expected.

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.

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!

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.

I've been using this every night for a few weeks and I absolutely love it! I have oily skin, large pores, and some rosacea. This controls oil, minimizes the appearance of pores, and gives overall hydration. My makeup sits beautiful on top of it as well if I decide to use it in the mornings. It doesn't make me break out, either! Thank goodness!! I highly recommend this product!

The quality of this product is amazing! Forever will be part of my routine. I used it once (entire bottle), then switched to something else-for no good reason. Poor choice. Immediately reordered this. My skin is so soft and my pores are significantly smaller almost immediately when using this. Great value. Light scent. Not sticky. No irritation. I will continue purchasing
