I’ve been using the KSECRET Seoul 1988 Niacinamide 15% + Yuja serum for a few weeks now, and overall I have mixed but mostly positive impressions. The formula is quite powerful — 15% niacinamide is a high concentration, and combined with yuja extract (rich in vitamin C), it really targets uneven skin tone and post-acne marks. I noticed my skin looks brighter and more even, with a subtle healthy glow. The texture is lightweight, absorbs quickly, and doesn’t feel sticky, which makes it easy to use both morning and night. It also didn’t clog my pores, which is a big plus. However, because of the high percentage of niacinamide, my skin needed some time to adjust. I experienced a bit of irritation at the beginning, so I’d recommend introducing it slowly, especially if you have sensitive skin. Overall, it’s a great option if your goal is brightening and improving skin tone, but it’s definitely more suitable for people who are already used to active ingredients.

I have been using this product for a few weeks now and I am really happy with the results. My skin type is sensitive and dry, so I am always careful when trying new skincare products. I decided to try this because I saw many good reviews, and honestly it did not disappoint. The texture of the product is very smooth and lightweight. It absorbs into the skin very quickly without leaving any sticky or heavy feeling. I love how comfortable it feels on my face, especially because some products for sensitive skin can feel thick or irritating. After using it consistently, I noticed that my skin feels much more hydrated and calm. It helps reduce dryness and makes my skin look healthier and more refreshed. I also like that it layers well with the rest of my skincare routine and doesn’t cause pilling when I apply sunscreen or makeup on top. Another thing I really appreciate is that it did not cause any irritation or redness on my skin. Since my skin is quite sensitive, this is very important

Muy satisfecha con mi compra
