Why I Rate Niacinamide So Highly

I remember when I first tried niacinamide about three years ago. To be honest, I was skeptical. Every ingredient seems to promise the world these days. But this one actually delivered.

I had been struggling with enlarged pores on my nose and cheeks for years. Nothing worked. Then a friend recommended a serum with 10% niacinamide. Within eight weeks, I noticed my pores looked smaller. Not gone completely, but noticeably less visible. That was when I became a believer.

Since then, niacinamide has become a staple in my daily routine. I use it morning and night, and I have genuinely seen improvements in my oil control, my skin texture, and even the faint dark marks left over from old breakouts.

What Actually Is Niacinamide?

Let me get a bit sciencey for a moment, but I will keep it simple.

Niacinamide is a form of vitamin B3 (niacin). Unlike niacin (the one that causes facial flushing), niacinamide is gentle and does not irritate the skin. It is water soluble, which means it sinks into the skin easily without leaving any greasy residue.

You will find it in all sorts of products, from serums to moisturisers to toners. It is one of the most stable ingredients in skincare, meaning it does not break down quickly when exposed to light or air.

The Benefits (And Why They Matter)

Here is the thing about niacinamide: it does not just do one thing. It tackles multiple skin concerns simultaneously. That is rare.

1. Pore Minimising

This is what made me a fan for life. Niacinamide helps regulate sebum production, which means your pores stay cleaner and less stretched. When your skin is not constantly producing excess oil, pores have a chance to shrink back.

I noticed the biggest difference on my nose and chin. Those areas used to look like little craters by midday. Now, they are much smoother.

2. Oil Control

If you have oily or combination skin, this is huge. Niacinamide tells your sebaceous glands to calm down a bit. It does not dry you out like harsh alcohol based products do. Instead, it actually balances your skin.

I used to blot my face three times a day. Now, maybe once, and only in summer.

3. Brightening and Even Tone

Niacinamide interrupts the process that creates dark spots and hyperpigmentation. It blocks the transfer of melanin to the surface of your skin. Over time, this fades post acne marks, sun spots, and general unevenness.

After my acne cleared up, I was left with red marks on my cheeks. They faded significantly after about four months of consistent niacinamide use. I was genuinely surprised.

4. Strengthening Your Skin Barrier

This is one of those benefits people do not talk about enough. Your skin barrier is your first line of defence against environmental damage, bacteria, and water loss.

Niacinamide boosts your skin natural barrier function. It increases the production of ceramides and fatty acids that hold your skin cells together. Stronger barrier equals healthier skin, equals less sensitivity.

5. Anti Aging Benefits

While niacinamide is not a retinol, it does have anti aging properties. It boosts collagen production, which keeps your skin firmer. It also helps with fine lines and wrinkles over time.

I am in my thirties now, and I use niacinamide partly for prevention. Better to start early than try to reverse damage later. If you want to learn more about building an anti aging routine, check out my retinol guide which pairs brilliantly with niacinamide.

6. Calming Redness and Rosacea

If you have sensitive skin or rosacea, niacinamide can help. Its anti inflammatory properties calm redness and irritation. Unlike vitamin C or AHAs, it is generally well tolerated by sensitive skin types.

How To Use Niacinamide In Your Routine

One of the best things about niacinamide is how easy it is to use. It plays well with almost everything.

When To Apply It

You can use niacinamide twice daily, morning and night. I personally apply it after cleansing and toning, before my heavier serums and moisturiser.

Here is my typical order:

1. Cleanser, check out my guide to the best face cleansers for recommendations
2. Toner, if I use one
3. Niacinamide serum
4. Vitamin C in the morning or retinol at night
5. Moisturiser, my moisturiser guide has great options for every skin type
6. SPF in the morning, sunscreen is non negotiable

What Concentration Do You Need?

This is a common question. Here is what I have learned:

• 2-5% - Great for beginners and sensitive skin
• 5-10% - The sweet spot for most people, effective but still gentle
• 10%+ - Potentially irritating for some, not necessarily more effective

I started with 5% and worked up to 10%. If you have never used niacinamide before, start lower and see how your skin reacts.

Can You Use It With Other Ingredients?

Yes. Niacinamide is one of the most compatible ingredients out there. It works with:

• Vitamin C, they complement each other beautifully. my vitamin C guide has my top picks
• Retinol, it helps reduce retinol induced irritation
• Hyaluronic acid, hydration plus oil control equals balanced skin. Hyaluronic acid is another ingredient I swear by
• AHAs and BHAs, use at different times, niacinamide in the morning, exfoliants at night

The Only Combination To Avoid

You might have heard that niacinamide and vitamin C should not be used together. This is an outdated myth. They work fine together. Ignore anyone who tells you otherwise.

My Favourite Niacinamide Products

Here are some I have actually tried and can recommend:

Budget Friendly

The Ordinary Niacinamide 10% plus Zinc 1%, at around £5, this is incredible value. It does contain zinc, which helps with acne. The texture is slightly viscous but absorbs well. This is where I started my niacinamide journey. You can grab this at Lookfantastic where they have 20% off.

Mid-Range

Paula Choice 10% Niacinamide Booster, this is a corrector that you can mix into any product. Lovely lightweight formula, great for targeting specific areas. Sephora UK stocks this if you want to save 15%.

CeraVe PM Facial Moisturiser, contains 4% niacinamide along with ceramides and hyaluronic acid. Perfect if you want simplicity. Available at most UK chemists and supermarkets.

Luxury

SkinCeuticals Metacell Renewal B3, this is the one that converted me. It is pricy but the texture is gorgeous, absorbs instantly and leaves no residue. get exclusive discounts at Elemis with my code, or browse Charlotte Tilbury for luxury formulations that pair beautifully with niacinamide.

Who Should Use Niacinamide?

Honestly? Pretty much everyone.

If you have oily skin, yes. If you have dry skin, yes. If you have sensitive skin, yes. If you have mature skin, yes.

The only exception might be if you have a specific skin condition or are using certain medications. If you are unsure, chat with a dermatologist.

My Personal Tips

After three years of daily use, here is what I have learned:

1. Consistency matters more than concentration, using 5% every day beats 20% occasionally
2. Give it time, do not expect miracles in a week, give it two to three months
3. Patch test first, even though niacinamide is gentle, always test a small area first
4. Store properly, keep it in a cool dark place, it lasts about six to twelve months once opened

Common Questions About Niacinamide

Does niacinamide cause purging?

Unlike retinols and acids, niacinamide does not typically cause purging. If you break out after starting it, it might be the formulation, some contain oils or other comedogenic ingredients, rather than the niacinamide itself.

Can I use it while pregnant?

Niacinamide is generally considered safe during pregnancy, but always check with your doctor or midwife first.

How long does it take to see results?

For pore size and oil control, you might see changes in four to eight weeks. For brightening and anti aging benefits, give it three to six months.

Can I use it under eye cream?

Yes, niacinamide is gentle enough for the under eye area. Just avoid getting it directly in your eyes.

The Bottom Line

Niacinamide is one of those rare ingredients that actually lives up to the hype. It is versatile, affordable, gentle, and effective. What is not to love?

If you have never tried it, I genuinely recommend giving it a go. Start with a lower concentration and see how your skin responds. Once you see the benefits, you will understand why it has become such a skincare staple.
