TIRTIR Niacinamide 20% Serum (often known as the Niacinamide 20% Serum or part of their specialized treatment lines) is a high-potency formula designed for targeted skin correction. Because 20% is an exceptionally high concentration of Niacinamide (Vitamin B3), this serum acts as an intensive treatment. 

Advanced Pore Minimization & Texture Refining

  • How it works: High-concentration Niacinamide helps normalize sebum (oil) production. When pores aren't stretched out by excess oil and debris, they naturally tighten and appear smaller.
  • Result: It significantly smooths out rough skin texture and orange-peel skin appearance

Powerful Hyperpigmentation & Dark Spot Fading

  • How it works: Niacinamide inhibits the transfer of melanin (pigment) to the skin's surface cells.
  • Result: It targets stubborn dark spots, post-acne marks (PIH/PIE), sun damage, and overall uneven skin tone, leading to a much brighter complexion.

Intensive Sebum and Acne Control

  • How it works: It regulates the sebaceous glands to reduce excess oiliness without stripping the skin of moisture. Its inherent anti-inflammatory properties help soothe active breakouts.
  • Result: A noticeable reduction in greasy shine, fewer clogged pores, and a calmer, less acne-prone canvas.

Barrier Support & Anti-Aging

  • How it works: Niacinamide stimulates the natural production of ceramides and fatty acids in the skin barrier.
  • Result: It strengthens the skin's defense system, locks in moisture, and helps plump the skin to reduce the appearance of fine lines.

Size: Medium, Color: Dark Cappuccino
The dark cappuccino brown is pretty. This is a favorite just because of the color of the tote. The inside lining color makes it easy to find items. I like it so much I ordered the black one.

Love the style but it doesn’t hold shape
Size: One Size, Color: Vanilla
I am big fan of the Lucky Brand. This tote disappointed simply because it was floppy. So if you set it down it just collapses instead of holding shape. So it wasn’t what I was looking for in a tote. I was really excited about this bag because I love the style and color. But I ended up returning it.

Super cute… but not what the listing is
Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
First of all, this listing is entirely inaccurate, as other reviews say, the picture is of a larger bag when in reality you are sent something much smaller and without the small wallet. I wanted the smaller bag, so I ordered it intentionally, but if you are looking for the larger size, do not order this. I included a side by side comparison of the two bags. The lighter bag is the size this listing is supposed to be (that I owned previously) and the smaller one is the one I was sent. That being said the smaller bag is super cute and so similar to the Brooklyn bag! Just be aware that it does not match the listing :)

Size: One Size, Color: Dark Cappuccino, Size: One Size, Color: Dark Cappuccino
This purse has a good size for an every day purse. It’s a pretty style purse, and reminds me of the Coach brooklyn shoulder bag. I’m not too crazy about this bag since the material is thin and flimsy, but I should be okay.
