TIAM Vita B3 Source

It really feels soft and absorbs well. And it has a faint scent that I like.

My skin is a bit sensitive and prone to breakouts. I started using it and immediately developed blemishes. It doesn't seem to suit me.

Those with sensitive skin may want to consider purchasing it..!

This serum contains 10% niacinamide, which helps brighten the skin tone, alleviate acne scars and redness, and provides overall moisturizing effects. I have been experiencing persistent and painful cystic acne breakouts since December, leaving behind reddish and bluish marks. I initially used a product with 5% niacinamide, but after my skin became accustomed to the ingredient, I switched to this serum with a higher concentration. However, those new to niacinamide should exercise caution. The serum has a transparent and thin consistency, not as watery as a toner but with a slightly thicker, more viscous texture. It is completely fragrance-free, which is a great advantage for those sensitive to scents. It absorbs relatively quickly, leaving a slight tackiness, but this eventually dissipates. After absorption, the skin feels soft and smooth. Using this serum has helped fade the reddish marks, reduced sebum production, and naturally diminished blackheads and whiteheads.

Morning and evening use is possible, but caution is advised when combining with other active ingredients such as retinol and vitamin C. This product contains 10% niacinamide, so if your skin is not accustomed to it, it may actually cause severe breakouts or worsen acne.
