If you struggle with oily skin, enlarged pores, or stubborn acne marks, you have probably tried dozens of products that promise clear skin but leave your face dry, irritated, or greasy. I decided to test the

Purist Niacinamide 10% + Zinc Clarifying Serum

for 14 days and track every change honestly.

Spoiler: I did not wake up with flawless skin overnight, but by the end of two weeks, my skin looked calmer, less oily, and noticeably more even.

Why I Tried It

My main concerns were simple: excess shine around my nose, small breakouts before my period, and dark marks left behind by old pimples. I wanted one lightweight serum that could control oil without damaging my skin barrier.

The Purist serum combines Niacinamide, Zinc PCA, Alpha Arbutin, Hyaluronic Acid, Glycerin, Aloe Vera, and Allantoin. Niacinamide helps balance oil, support the skin barrier, and improve uneven tone, while Zinc PCA targets shine and congestion. Hydrating ingredients such as hyaluronic acid and glycerin help prevent that tight, stripped feeling that many oil-control products cause.

That combination convinced me to give it a proper two-week trial.

Day 1: First Application

I cleansed my face, patted it dry, and applied two drops of the serum to my face and neck. The texture felt watery and lightweight. It absorbed quickly, left no sticky film, and worked well under my moisturizer.

My skin felt hydrated rather than oily. I followed it with sunscreen in the morning, as recommended.

Result: No irritation, no redness, and no heavy shine.

Days 2–4: Less Shine, More Comfort

By the third day, I noticed the biggest early change: my T-zone stayed matte for longer. Usually, my nose started shining within a few hours, but my skin looked more balanced throughout the day.

I also appreciated that the serum did not dry out my cheeks. Many products designed for oily skin remove too much moisture, but this one felt more like a balancing treatment.

Result: Reduced midday oil and smoother-feeling skin.

Days 5–7: Calmer Breakouts

During this week, I developed one small pimple near my chin. Normally, it would stay red and irritated for days. This time, the area looked less inflamed, and the mark faded faster than usual.

The serum did not magically erase acne, but it helped my skin stay calm. I used it twice daily, morning and night, and kept my routine simple: gentle cleanser, serum, moisturizer, and sunscreen.

Result: Less redness and fewer new clogged pores.

Days 8–11: Pores and Texture

This was when I began seeing visible improvement in texture. The small bumps around my nose felt smoother, and my pores looked less obvious, especially in natural daylight.

My foundation also applied more evenly. Because the serum created a smooth base without pilling, I could wear makeup without worrying about excess shine breaking through.

Result: Refined texture, smaller-looking pores, and easier makeup application.

Days 12–14: More Even Skin Tone

By the final days, the old acne marks on my cheeks looked softer and less dark. They had not disappeared completely, which is realistic after only two weeks, but my overall complexion looked clearer and more uniform.

My skin also felt stronger. I experienced no stinging, peeling, or sensitivity, even though I used the serum consistently twice a day.

Result: Brighter, calmer, and more balanced skin with faded post-acne marks.

What I Loved

• Lightweight, non-sticky formula that absorbs quickly

• Controls oil without leaving skin dry or tight

• Helps calm redness and irritation

• Improves the appearance of pores and rough texture

• Layers comfortably under moisturizer and makeup

• Suitable for oily, combination, and acne-prone skin

The formula includes niacinamide, zinc PCA, alpha arbutin, hyaluronic acid, glycerin, aloe vera, and allantoin, which makes it a well-rounded option for people who want clarity without harsh exfoliation.

What Could Be Better

If you expect to remove deep acne scars or severe pigmentation in two weeks, this serum will not do that. Consistency matters. I noticed gradual improvement, not an overnight transformation.

Also, if your skin is very sensitive, start with once-daily use. Avoid layering it with strong acids or vitamin C in the same routine, as the brand recommends.

My Honest Ratings

How to Use It for Best Results

1. Cleanse your face and pat it dry.

2. Apply 2–3 drops to your face and neck.

3. Press gently until the serum absorbs.

4. Follow with moisturizer.

5. Apply sunscreen every morning.

Use it twice daily for the best results. Protect your skin from the sun, because sunscreen helps maintain an even tone and prevents dark marks from becoming darker.

Final Verdict: Is It Worth It?

Yes. The

Purist Niacinamide 10% + Zinc Clarifying Serum

is worth trying if you want to control oil, reduce breakouts, refine pores, and fade post-acne marks gradually.

After 14 days, my skin looked healthier, felt smoother, and stayed shine-free for longer. It is not a harsh quick fix; it is a practical daily serum for anyone who wants balanced, clear, and comfortable skin.

If oily skin, clogged pores, or acne marks are your main concerns, add this serum to a simple routine and give it at least three to four weeks. Based on my experience, consistent use delivers real, visible improvement.
