Who – For Oily, Acne‑Prone Skin With Visible Pores and Dark Spots

This MaryenB NTZ20 Niacinamide 20% Serum is made for oily and combination, acne‑prone skin that struggles with enlarged pores, frequent breakouts and lingering dark spots. If your T‑zone gets shiny quickly, pores look more noticeable than you would like and old blemishes leave visible marks, this high‑strength niacinamide facial serum is designed to fit into a simple daily routine. It is a good choice for people who want to improve the look of excess shine and uneven tone without using harsh, drying products.

What – High‑Strength Niacinamide 20% Facial Serum With Zinc and Tranexamic Acid

NTZ20 is a concentrated niacinamide 20% facial serum with 2% zinc PCA and 2% tranexamic acid, created to support clearer‑looking, more balanced skin. This serum targets key concerns such as enlarged pores, excess sebum, recurring blemishes and visible dark spots from past breakouts or sun exposure. The formula focuses on refining the look of pores, reducing the appearance of discoloration and helping the complexion look smoother and more even over time.

How – How This Serum Helps With Pores, Oil and Dark Spots

At the heart of this serum, 20% niacinamide works to help regulate the feel of excess oil and improve the look of enlarged pores, so skin can appear more refined and less congested. Zinc PCA supports clearer‑looking skin by helping to balance oil on the surface, which is especially useful for acne‑prone and oily areas like the T‑zone. Tranexamic acid is included to help reduce the appearance of dark spots and uneven tone, particularly marks that remain after blemishes or from sun exposure, so the overall complexion can look more even and bright. Soothing ingredients such as aloe, allantoin and sodium hyaluronate help keep the formula comfortable to use, even at a high niacinamide level.

Hero ingredients – Targeted Blend for Clarity and Even Tone

The hero ingredients in MaryenB NTZ20 are chosen to work together on pores, oil and visible discoloration.

• 20% niacinamide to help refine the look of pores, balance sebum and support a stronger skin barrier.

• 2% zinc PCA to support clearer‑looking skin and help reduce the feel of excess shine on oily, acne‑prone areas.

• 2% tranexamic acid to help improve the look of dark spots and uneven tone from past blemishes.

These actives are supported by aloe vera extract for a soothing, hydrated feel, sodium hyaluronate for lightweight moisture, and additional ingredients like allantoin and caffeine to help keep the skin looking fresh and comfortable. The result is a focused, multi‑tasking serum for people who want one step to address pores, oil and tone together.

Texture & routine – Light, Layer‑Friendly Serum for Daily Use

The texture of this niacinamide 20% serum is water‑light and non‑oily, so it sinks in quickly without leaving a heavy film, making it easy to layer under moisturizer, sunscreen and makeup. After cleansing and using a gentle toner, apply a small amount of MaryenB NTZ20 serum over the face, focusing on areas with visible pores, excess shine or dark spots. Follow with a non‑comedogenic moisturizer; in the morning, always finish with a broad‑spectrum sunscreen to help protect skin while you work on visible discoloration. Most users can start with once‑daily use in the evening and then adjust to morning and evening if their skin responds well.

Who should avoid – When to Use With Extra Care

Because NTZ20 is a high‑strength niacinamide serum, very dry, compromised or highly sensitive skin may find it too intense for everyday use. If you are new to niacinamide, have a history of reacting to high‑percentage active ingredients or your skin barrier is already irritated, start slowly and perform a patch test before applying it all over the face. Those already using several strong actives—such as acids, retinoids or other high‑percentage niacinamide products—should simplify their routine and introduce MaryenB NTZ20 gradually, and stop using it if they notice strong burning, unusual redness or persistent discomfort.
