Lately, I’ve been paying more attention to serums because my skin changes depending on stress, weather, and even lack of sleep. Some days it looks healthy and calm, but on other days it feels tired and uneven. That’s why I became curious about niacinamide serums. I kept seeing people talk about them everywhere, so I finally decided to try a few myself.

Among the ones I used the longest were Somethinc 10% Niacinamide + Moisture Serum and Skintific 10% Niacinamide Brightening Serum. Even though they share the same main ingredient, the experience felt surprisingly different.

1. Somethinc 10% Niacinamide + Moisture Serum

Somethinc 10% Niacinamide + Moisture Serum was one of the first niacinamide products that actually felt comfortable on my skin. I remember expecting something strong or drying because of the percentage, but instead it felt light and calming. The texture spread easily, and I didn’t need much product each time. What I personally liked most was the moisture it gave. Some brightening serums make my skin feel tight afterward, but this one felt balanced.

2. Skintific 10% Niacinamide Brightening Serum

Skintific 10% Niacinamide Brightening Serum gave me a slightly different impression from the beginning. The formula felt richer compared to the Somethinc serum, and my skin looked more dewy right after application. On days when my skin appeared tired, this serum gave a brighter and healthier look almost instantly. I also liked how soft my skin felt after using it for several nights in a row. It gave that smooth texture people usually look for when they want their makeup to sit better.

Using these two serums taught me that even products with similar ingredients can create completely different experiences. Somethinc 10% Niacinamide + Moisture Serum felt lighter, simple, and easy for everyday routines. Meanwhile, Skintific 10% Niacinamide Brightening Serum gave my skin a richer glow and a smoother finish that I enjoyed during busy weeks.
